Electrical Resistivity ER surveys showed a naked burial produced large, low-resistivity anomalies for up to four years, but then the body became difficult to image. This process of interrogation is then repeated for all other figures. Brilis, G. Inversion of the recorded data produced resistivity models with average RMS errors of around 2 after five iterations, which indicated very good fit between the data and models. If you do so with no question in mind, you learn nothing. Can electrical resistivity surveys and GPR successfully locate clandestine burials of homicide victims up ehat ten years after burial Yes but this depends what does investigator mean in science terms the style of burial. Measurement is fundamental in experiments and studies of the social sciences, there are scales of measurement, among them are:.

Quantitative methods, qualitative methods or combination of research: an approach in the social sciences. Roberto Rendón-Medel 2. Eileen Salinas-Cruz 1. Francisca del Rosario de la Cruz-Morales 3. Dora Ma. Sangerman-Jarquín 4. Carretera Ocozocoautla-Cintalapa km 3, Ocozocoautla, Chiapas. Chapingo, Estado de México. Carretera Los Reyes-Texcoco km The eternal discussion of which method to use when initiating an investigation has not come to an end, since hard or exact sciences expose that scientific rigor must take a series of sequenced steps to accepting or not accepting a hypothesis, the philosophical sciences favor the use of tools and techniques based on ethnography to try to understand the phenomenon and the object of the investigation, because of this, this essay aims to help young researchers to be more clear in selecting their method of evaluation in one investigation, without being exclusive one method of the other, but rather complementary.

Which are listed below: a conception of the idea to give an example of each of the 3 types of symbiotic relationships b what does investigator mean in science terms the research problem; c developing the theoretical framework; d hypothesizing; d selection of the appropriate method of investigation; f sample what are relationship attachment styles g data collection; h data analysis; i presentation of results; and j new research ideas.

The goal of any science is to acquire knowledge and the choice of what does investigator mean in science terms most appropriate method that allows us to know reality is a fundamental point in the process. Regarding research methods these are closely related to the data collection instruments, among social scientists there is a trade-off between using quantitative or qualitative methods; however, in a research paper quantifiable issue does not have to be what does investigator mean in science terms to qualitative what does investigator mean in science terms Orozco quantitative and qualitative methods are not supported from the epistemological point of view -and epistemology: teaching what does investigator mean in science terms fundamentals and methods of scientific knowledge- Larousse Dictionary, ; however, they can be complementary, and that there is the aspiration among social scientists have an integrated quantitative and qualitative research.

The absolute opposition between quantitative and qualitative methods, is a false argument, in front of it is supported by a complementary, but in larger terms of equality, since the testing and verification to prove the validity of the investigations should be what are the bad effects of online classes by researchers themselves, not being reserved nor what quantitative or qualitative Pedone, Within all analyzes of quantitative methods we can find a characteristic based on positivism as an epistemological source, which is the emphasis on the precision of measurement procedures.

Another predominant feature of quantitative methods is the subjective and intersubjective selection of indicators through concepts and variables of certain elements of processes, facts, structures and people. These elements do not form in their entirety, processes or people, hence the debate arises between quantitativists who never see an integrated phenomenon, but always sets of particles of the phenomena related to observation, and qualitative that cannot perceive the generated elements that share the phenomena.

Taylor and Bogdan mention that the qualitative methodology unlike quantitative is more than a set of techniques to collect data, they indicated at least 10 technical characteristics and qualitative methods compared to quantitative:. In qualitative methodology the researcher sees the stage and people in a holistic perspective, people, scenes or groups are not reduced to variables, but seen as a whole.

Qualitative investigators are sensitive to the effects that they cause on people who are the subject of their study. They conclude that the methods serve the investigator, never is the researcher the slave of a procedure or technique. Cookpointed out that there are two methods for collecting data: qualitative and quantitative. The more obvious distinction to be drawn between the two why doesnt my samsung tv stay connected to the internet that quantitative methods produce numerical data and qualitative result information or descriptions of situations, events, people, interactions, and observed behaviors, direct quotations from people and extracts or passages documents, correspondence, records and case studies.

Quantitative research is that which collect and analyze quantitative data, meanwhile quantitative which prevents quantification; however, records are made through narrative, participant observation and unstructured interviews. Qualitative methods for data collection play a very important role in impact assessment because they provide valuable information to understand the processes behind the results. According to the World Bank can be used to improve the quality of the survey-based quantitative assessments as they help to generate assessment hypotheses, strengthen the design of questionnaires for surveys, and broaden or clarify the findings of the quantitative evaluation.

Meanwhile Grawitz posed as a question whether the fact can the social sciences take advantage of the instrument of quantitative methods? What is a popular dating site this regard, it did not find a conclusive answer, since certain sectors of some social sciences lend themselves better than others to a quantification.

In the social sciences Grawitz indicated that there is an error in the passage from the qualitative to the quantitative, since the second method depends on the data collected primarily by the first, which are collected and processed. Examples of the above are the interviews, group observations, document analysis among others. For this author, quantification is nothing more than a second stage in the collection of qualitative data.

Qualitative studies are intensive research on a very small scale, in which the daily experience of people and their communities in different times and spaces is explored. In these works, the position of the investigator, their experiences, perspectives and prejudices are significant aspects in the development and results of research Philip, Reichardt and Cook indicated that qualitative research offers the opportunity to focus on finding answers to questions that focus on the social experience, while quantitative research is characterized what does investigator mean in science terms a global conception based in logical positivism with a particularity is oriented to the objective results.

These authors mention that qualitative what does investigator mean in science terms are not only quantitative questions and answer only to conclude by saying that there is no fundamental clash between the goals and capabilities what does investigator mean in science terms the methods or qualitative or quantitative data. Similarly, Calero concluded that the use of either method depends on the moment that the researcher is interested in privileging generation of theory or transformation of reality and topic that is chosen to investigate.

The quantitative studies were becoming more obsolete than ever generalizations were made from smaller samples. Table 1 Advantages and disadvantages of qualitative and quantitative methods. In both methods requires intentionality and systematize information, the use of instruments in the quantitative are those that guide the research and in the qualitative epidemiological society definition the processes that guide.

In quantitative methods data can be accumulated and compared to have common data, while qualitative methods can cover the entire spectrum of a population whose distribution is considered normal and are also personalized. In general terms the validity refers to the degree to which an instrument actually measures the variable to be measured.

Validity is a concept which can be different types of evidence: content validity which refers to the degree to which an instrument reflects a specific content domain which is measured, the validity criterion establishes the validity of an instrument of measurement by comparing it with some external criterion and the validity of the construct refers to the degree to which a measurement is consistently related to other measurements according what does investigator mean in science terms hypotheses derived theoretically and that concern the concepts or construct.

Quantitative methods are stronger in external validity as a representative sample equivalence class class 12 questions the population make inference of said population from a sample with a confidence and precision defined, thus limiting the methods qualitative is the difficulty to generalize, on the other hand quantitative research with the hypothesis tests not only eliminates the role of chance discard or reject a hypothesis, but to quantify the importance of a phenomenon by measuring the relative risk reduction Calero, Regarding reliability in social research using quantitative methods, so that the results are more reliable the required sample size should be increased, therefore the sample size is directly proportional to the desired reliability Snedecor and Cochran what does investigator mean in science terms On the other hand, the same authors indicate that a higher sample size will be required at higher precision; the sample size is directly what are the female groups to the accuracy but inversely proportional to the value of accuracy; i.

Grawitz indicated that the precision of an instrument is usually defined by their sensitivity to the variations that must register. The precision of an instrument is usually defined by its sensitivity to the variations to be recorded, in the case of the social sciences, it will be the accuracy with which the position of an individual is placed in relation to the characteristic to be measured, for example an opinion poll will only give a proportion of supporters or related subjects, nonpartisan or without opinion.

Hence accuracy validity and reliability closely aligned Grawitz, Measurement is fundamental in experiments and studies of the social sciences, there are scales of measurement, among them are:. In quantitative studies should determine what type of measurement is required in the above described scale; however, social science data collected can be traditional or local measures so we have to make the respective conversion, so that can be read in the metric system.

There must be a compatibility of concepts between the researcher and the interviewee, especially when the answers are obtained in regional measures. In the measurement of temporality there is no social process variables is infinite. Every measurement must have two essential requirements. Reliability and validity. The reliability of a measurement refers to the degree to which their repeated the same subject or object application produces similar results.

However, reliability can be affected by various factors among which improvisation, because choosing an instrument lightly and development of an instrument either shows a lack in with knowledge and is therefore a tool bit reliable and invalid. Another factor that affects reliability is the development of instruments abroad without being validated in the context where the research will be developed.

Therefore, the concepts culture and time are valid for this case. The third factor that affects reliability is that the instruments are inadequate for the people linear equations grade 8 questions whom they are applied. The fourth factor that affects the reliability of an instrument is the conditions in which the instrument is applied, such as cold, heat, wind or rain, noise among others.

Applicability of difference between effect and affect meaning in hindi, this depends on the nature of the study or investigation, since not 420 angel number meaning soulmate instruments can be used for all types of investigations, such as depth interview only it focuses on an individual while a survey can represent all a population.

On the other hand, participant observation is useful as social phenomena and life cycles are investigated, anthropologists have in this technique a valuable tool. All scientific research is connected between the research topic and the purpose of the investigation, about Dieterich mentions that the research topic is expressed in a statement or proposition, while the object of research is the real phenomenon the sentence or phrase refers study. Therefore, the object of research is an aspect of reality, in which our interest in knowledge is concentrated and cannot be explained what are base pairs in dna held together by or without use of theory.

Therefore, Dieterich indicates that the object of study in a scientific analysis is a real, verifiable phenomenon that exists in the universe independently of the interest of the knowledge and subject of research that a person might have on it. Social science is said that the research object changes when a part of your reality is modified by internal or external factors. For example: s i the object of research are social relations between actors in a particular region, then qualitative methods are vital; on the other hand, if what you want is a typology based on productivity actors the same region, then qualitative methods are indicated.

Qualitative methods are an important part of social scientific research because they can give us information about the characteristics of social groups, relationships with their environment and reproduction systems, while for a census of the same population then the quantitative data are the most accurate, since in the end we can give clear idea of the quantifiable characteristics of each of study subjects. The quantitative model generalizes and presupposes, to achieve greater validity, a well-developed qualitative and theoretical knowledge, a condition that is often out of the question in the practice of quantitative research.

Criticism of quantitative research is not directed against what does investigator mean in science terms method in general, but against the unique application of it to investigate social reality. Before establishing quantitative measurement, it is worthwhile to qualify the problems and needs and both determine priorities as factors to be investigated.

From there one can resort to the measurement of what does investigator mean in science terms variables through the determination of the indicators. Also note here love is not worth it questions that need to be raised such as:. It is quantify the phenomenon that we already see through what indicators? Is it precise the information that we get and is valid as well as reliable?

Is there an adequate analysis to know if what people say corresponds to what it really is or what it does? If these questions can be answered positively, quantitative research is likely to provide us with valuable additional information. Of the qualitative instruments are:. Depth interviews: the depth and interviews involve asking questions, listening and recording the answers and then ask other questions to clarify or expand a particular topic.

Questions are open and interviewees must express their perceptions in their own words. The informal interview is spontaneous generation of questions in the natural flow of interaction. This type of interview is appropriate when the evaluator wants to maintain maximum flexibility for guiding questions the direction that seems the most appropriate, according to information arising in a conversation with one or more people.

The researcher with this approach is flexible and highly sensitive to individual differences, changes in the situation and the emergence of new information. However, a weakness is that it can generate less systematic data, whose classification and analysis will be difficult and slow. The semi-structured interviews: involve the preparation of an interview guide that lists a predetermined questions or topics to be treated together.

This ensures that you basically get the same information from several people. Even so, there is plenty of flexibility. The advantage of the style of the interview guide is the fact interviewing different people become more systematic and comprehensive, as the issues to be discussed are delineated. The weakness of this approach is that it allows the interviewer guide topics or topics of interest that were not what does investigator mean in science terms at the time of the preparation of the guide.

Open standardized interview consists of a set of open questions carefully formulated and ordered in advance. The interviewer asks the same questions to each of the interviewees, essentially with the same words and in the same order. This type of interview may be especially appropriate when there are several interviewers and the evaluator wants to minimize the variation of the questions.

Life histories: it is the widest interview, for anthropologists life histories are the set of multiple interviews, it seeks to know why the subject is acting as it acts according to what has been. Case studies: these are made experiential learning model adalah comparative purposes, is to be an in- depth study is the effort to integrate into an object of research all constituent information of the object and not just part of the information.

Survey: puts the respondent in a passive role. He feels examined, even by a strange being and will be unlikely to respond in all respects, then in a discussion with acquaintances. For the characteristics of the survey characteristics, the unique character of the person, of a process or a social phenomenon, dividing them into a number of features, elements or indicators and then add them is lost.

The survey method is too static. The survey captures what in a given moment has manifested but does not assimilate in the short term the changes that can occur in society.
