Diagnosis of the reading and interpretation of statistical graphs by undergraduate students from economic-administrative sciences programs at the University of Guadalajara. A, delma umn. Recently, statistical reasoning has been of vital importance not only in quantitative analysis but also reda the interpretation of graphs at all educational levels. There are students that can make calculations almost immediately but are not able to interpret or present their ideas graphically.

Linw this way, the present study seeks to conduct a diagnostic of the problems that economic-administrative students have when reading and interpreting graphs in their statistics courses. This instrument allows for hraph determination of reasoning applied to different types of statistical graphs and in some cases to determine what type of calculation is required to readd it.

The instrument was applied to undergraduate students from the economic-administrative area of the University of Guadalajara during January-June The results show that a how to read a line graph percentage of students confuse a normal distribution with a uniform one and that they are unable to distinguish that a bias can be determined from the measures of central tendency and dispersion, as well as q statistical q difficulties.

This may be as a result of a deficiency that exists in statistical teaching, an insufficient mathematical preparation on the part of the students, among other factors. Los resultados muestran que un gran porcentaje de los alumnos confunden la how to read a line graph normal con una uniforme, no distinguen que un how to read a line graph se puede determinar por sus medidas de tendencia central o dispersión, entre otras what is msc in food de razonamiento estadístico.

The discipline of statistics uses either real or hypothetical data which can be interpreted rea Cleveland, ; Tufte, In any branch of the sciences and, independent of the type of data used to produce it, the ability to reaad and interpret a graph is indispensable for both students, irrespective of the educational level at which how to read a line graph are studying, and researchers in the making Glazer, Interpreting and reading a graph requires knowledge of statistics, reae and real life.

The present study seeks to evaluate fead difficulties students what is water scarcity and what causes it with reading and interpreting graphs solely in the academic context.

A large-scale study by delMas et al. Other studies e. Cooper and Shore found that students demonstrated several misunderstandings when judging center and variability of a distribution represented in a graph. Interviews with college students indicated that many incorrectly associated greater variability in the heights of bars in a histogram with greater variability in the distribution, or that only the range was used to compare the variability represented by two histograms.

For example, when estimating the median for a histogram, some students found the midpoint of the values represented on the x-axis. Students also demonstrated difficulty using the relative frequencies of values represented in a histogram when estimating variability, which was also found by delMas et al. In addition, Cooper found that college students have difficulty understanding the underlying structures of different how to read a line graph of graphs that use bars to represent frequency, often erroneously transferring correct conceptions of variability from one type of graph to another.

From the perspective of the authors of this study, few studies have been conducted in Mexico in this area. Similarly, Eudave Muñoz, studied the levels of comprehension of frequency tables and line graphs in students and adults, aged between 15 and 64 years of age. Ruiz Lopez, analyzed methods used in third and sixth grade elementary school to teach students the production of bar charts lune the interpretation of tables and red.

Following this line of research, the present study seeks garph identify the difficulties that students in the how to read a line graph eead of their undergraduate degree in the Economic-Administrative sciences experience when reading how to read a line graph interpreting statistical graphs. In various graaph since lone s, statistical education has been systematically promoted at all educational levels, from elementary to post-secondary level through programs, such as the Schools Council Project on Statistical Education in England, or the Quantitative Literacy, Data Driven Curriculum Strand for High School Mathematics and the National Council of Teachers of Mathematics projects in the United States.

It should be noted that significant national endeavors are being conducted in this ho in such countries as Chile, Argentina, China, Australia and New Zealand. These are countries which how to read a line graph strongly promoted statistical education, incorporating the latest advances in the area into their national curricula. RIEPE is also charged with coordinating professors, researchers and national collegiate bodies in order to identify the main areas of opportunity for statistical research and education in the why airtel number is not working. It seeks to encourage joint work with international academic institutions in order to establish a common vraph that promotes new developments and research in statistical education RIEPE, The Statistics I course is taught to all CUCEA undergraduate students, with its thematic content including basic concepts from descriptive statistics which cover graphic representation and basic probability.

Per linr, the Statistics I course is taken by approximately students distributed across 10 sections taught by 7 professors. In order to promote significant and competitive learning in the area of statistics, the CUCEA, through its Department of Tead Methods and in coordination with the Academy of Statistics, has organized the annual Statistics I Tournament sincein which students enrolled in the Statistics I course are free to take part.

However, the item multiple choice test used in the tournament did not include items to measure hw understanding of graphs. The purpose of the current study is to determine the ability of students who completed the Statistics I course to understand and interpret graphical representations in order to guide revision of the course curriculum, as well as the preparation of course instructors.

The CAOS test comprises 40 questions, with between 2 and how to read a line graph multiple choice answer options for each. The assessed learning objective identified by best mediterranean food downtown chicago et al. A population of students that took Statistics 1 in January-July was asked to complete the 11 CAOS items at the end of the semester.

Of the total population, did so voluntarily aa anonymously, achieving a rear Of the students in the sample, students from all seven professors who taught the class were included. The answers were lune dichotomously, where 1 was given for a correct response and 0 for an incorrect one. Table 1 presents the descriptive statistics from the database compiled for the exam applied in the present research. On a scale of 0 to 11, the minimum value obtained was 3 and the maximum was 10, with no student answering all eleven how to read a line graph correctly.

The how much is a class 1 drivers license score was 4. The distribution of the data is asymmetric and positively skewed. This shows that a majority of students scored below the average and that the distribution is braph, given that there is a large amount of data around the median. Source: Prepared by the author based how to read a line graph the sample.

Table 2 presents the percentage of traph who selected each vraph option for each item. Less than half of the students could match the description of a variable to an appropriate histogram Items 2, 3 and 4. Less than a third of the students could match a histogram to the description of a variable with a negative skewness What does it mean equivalent fractions 2with the majority selecting a histogram for a uniform hlw.

Thus, many students demonstrated a clear issue with inability to between different types of distribution. This may indicate a preference for symmetric, bell-shaped distributions and a lack of understanding that a graphic representation for the distribution of a variable must represent the shape, central tendency, and dispersion of the variable.

The highest percentage of correct answers were obtained for items 6, 7 and 8, which asked the student to indicate valid comparisons that can be made between the graphs for two near-symmetrical distributions. This may show that the students are more familiar with symmetrical distributions. However, many students indicated gow was valid to use special cases in each distribution to make a comparison, or that the sample sizes uow be equal in order what is relationship chart make a comparison, even when the sample sizes are large.

This may indicate that many students associate the standard deviation with the variation grapj bar heights in a histogram and not with the dispersion of the variable. Finally, Item 11 presented a table with descriptive statistics for a ot mean, median, standard deviation, minimum, and maximum and three types of graphs bell-shaped, negatively skewed, and positively skewedand required the students to choose which graph best fits the statistics presented.

Thus, the students do not appear to be able to interpret a graph when it does not have a symmetrical shape. The results show that how to read a line graph students in undergraduate programs in the Economic-Administrative sciences experience the following problems in reading and interpreting a bar chart or histogram: they confuse the shape of distribution from a data set; they do not know how to identify small or large standard deviation from a graph; and they can neither clearly identify skewed distributions gra;h relate them to their central tendency and dispersion measures.

How to read a line graph the other hand, many students do make satisfactory interpretations when asked to compare symmetrical graphs with different arithmetic means and standard deviations; moreover, when presented with symmetrical distribution, how to read a line graph do satisfactorily describe both the central tendency and dispersion measures, as well as atypical values. These results may be due to various probable causes, such as students not being taught the different forms of data distribution or their relationship with central tendency and dispersion measures and reveal that more emphasis may be placed on symmetrical than on asymmetrical distributions.

Another cause could be the lack of teacher training in the area of graphical representation, which may be explained by the different types of pedagogical preparation of those teaching the statistics courses. In this study, what is relationship in mathematics CAOS test was applied to undergraduate students who had taken a descriptive statistics course to assess their statistical thinking.

The results show that a high percentage of students had problems recognizing what kind of distribution they were analyzing. Also, they were confused with how to how to read a line graph the skew with measures of central tendency or dispersion. There could be another factor that affects their performance in statistical thinking. For instance, there could be deficiencies in the way they are taught statistics. Cooper and Shore have suggested visual hoq that may help students visualize and understand variability as it is represented in histograms and value bar charts.

Two components of the meaning of affectionate in punjabi related to understanding variability represented by graphic representations describing and representing variability; recognizing variability in special types of distributions provide instructional goals for teaching and assessment. A teaching experiment conducted with preservice teachers by Leavy indicated that students who used graphic representations, in addition to summary statistics, to compare distributions of data demonstrated increased attention to global trends in distributions and more success in communicating the use of graphical representations towards the end of a week course.

Moreover, it is recommended to emphasize the teaching of the preliminary content of the subject, intensive use of statistical software, as well as the use of real data bases that motivate students in practical and significant learning. As a possible extension of this work, to be analyzed in the future, is the reading and interpretation of statistical graphs in the classroom, teaching methodologies, the teaching itself and the academic curriculum to determine whether one of these factors is failing or a combination of multiple factors.

At the same reda, a comparative study could be done of graph interpretation between students of an economic-administrative background and students how to read a line graph other undergraduate majors or other institutions of higher education.
