Question

Draw/Create a pareto chart for the data set described below. Recently, I had the opportunity to assist the Office of Engineering Outreach and Recruitment in the College of Engineering. One of our projects focused on the ethnic background for undergraduate students in Engineering. We gathered a random sample of 100 students and found the following frequencies for each the ethnicity categories below. Thirty-three students identified as Caucasian/White, forty-eight students identified as Hispanic/Latino(a), thirteen students identified as American Indian/Native American, and six students identify as Asian/Pacific Islander.

Answer 1

Solution: The data from the question is tabulated as below.

We will calculate the cumulative percentage for the number of student to draw the Pareto graph.

For Hispanic/Latino(a), cumulative %=48/(48+33+13+6)*100=48%

Caucasian/White, cumulative %=(48+33)/(48+33+13+6)*100=81% and so on.

Ethnicity Category	No. of students	cumulative(%)
Hispanic/Latino(a)	48	48%
Caucasian/White	33	81%
American Indian/Native American	13	94%
Asian/Pacific Islander	6	100%

The Pareto graph for the above data set is as below.
