Question

unit 4 test: graphs and describing distributions multiple choice
13 of 25
at a university, the breakdown of percent of students who take certain majors is given as follows: 18% math, 22% psychology, 28% business, 17% engineering, and 15% english. knowing this information, is it appropriate to represent the data in a pie chart?
yes, because we know the total sum of all of the percents adds up to 100
yes, because it is in percents, you always use a pie chart when you have percents!
no, because you do not use a pie chart when given percents
no, because not enough information is given

Explanation:

A pie chart is appropriate when data represents parts of a whole. Here, we check if the sum of percentages is 100% (18 + 22+28 + 17+15 = 100). Also, the data is about different majors (categories) as parts of the student population (whole). The second option is wrong as having percentages isn't the sole criterion (e.g., if sum ≠ 100, pie - chart not suitable). The third option is incorrect as pie - charts can use percentages. The fourth option is wrong as we have enough info (sum to 100).

Answer:

yes, because we know the total sum of all of the percents adds up to 100
