Create a series of graphs (histograms, polygons, bar graphs, etc.) that summarize your findings in items 3 and 4. In other words, create graphs that compare the means and standard deviations of the dependent variable by the levels of the independent variable of interest. Discuss your findings. items 3 and 4 are below and info or background info for the problem is at the very bottom under items 3 and 4. The only thing I need help solving and creating is this item #5 parts regarding graphs and summarization. These numbers are based on 29 students who completed a survey in my class if that helps.
item #3 Measures of Central Tendency-
Research question: What determines one’s GPA?
Hypothesis: Those who are younger than 25, sit in the front of the class, and have a study partner will be more likely to have a better grade than people who are opposite.
2. Work environment
How do the variables of (IV1) studying, (IV 2) Work environment, and (IV 3) Age affect (DV)Grade point Average?
People that are above 25
People that are below 25
People that sit in the front
People that sit in the middle
People that sit in the back
People that have a study partner
People that don’t have a study partner
This section presents a graphical analysis of the hypothesis by comparing the mean, standard deviation, and distribution of the respondent's CGPA based on their age, work environment, and studying.
Effect of Age on CGPA
We used graphs to compare the CGPA of students above 25 years to those below 25 years. We hypothesized that students below 25 years will have high CGPA than respondents above 25 years. Figure 1 shows the histogram of the distribution of CGPA by age.
