Question

Survey about favorite types of stores. What is the relative frequency for the number of students in the 4 categories:19 students clothing11 students electronics5 students pet15 students candy

Answer 1

students clothing: 19/50 or 0.38 or 38%

students electronics: 11/50 or 0.22 or 22%

students pet = 5/50 = 1/10 or 0.1 or 10%

students candy = 15/50 = 3/10 = 0.3 or 30%

1) Adding it up the number of students we have:

19 +11+ 5+15 =50

2) To find out the relative frequency, let's write a quotient between each category and the total number of students.

students clothing: 19/50 = 0.38

students electronics: 11/50 = 0.22

students pet = 5/50 = 1/10 = 0.1

students candy = 15/50 = 3/10 = 0.3

3) Hence the Relative frequency for all of these 4 categories are:

students clothing: 19/50 or 0.38 or 38%

students electronics: 11/50 or 0.22 or 22%

students pet = 5/50 = 1/10 or 0.1 or 10%

students candy = 15/50 = 3/10 = 0.3 or 30%
