Question

Determine which type of graph would most clearly depict the data described. a. The enrollment size at Austin Peay State University (APSU) over the past decade b. The size of each class-freshman, sophomore, junior, senior-for the current year at APSU c. The size of each class-freshman, sophomore, junior, senior for the current year at APSU, specifically comparing the genders of students in each category d. The enrollment sizes of all state universities across the country

Answer 1

a. Line Graph

Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs.

Since we are reporting enrollment size for the past decade/a period of time a line graph to represent should be appropriate.

b. Pie chart

Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time.

So we can use parts (freshman, sophomore, junior, senior ) size as part of whole APSU.

c. Bar Graph

Since we are specifically interested in comparing genders size comparison , so bar graphs can be used to for such scenarios where we are doing a neck to neck comparison.

d. Bar Graph

We again are interested in comparing the sizes of different universities across the country. so a bar graph could represent it well.
