Question

The employees of two companies were asked how many times they checked their email during weekends. The table below shows the numbers for each company: Company A 2 4 8 8 2 6 4 8 3 Company B 2 6 3 5 2 4 6 3 2 Based on the table, which of the following is true?

Answer 1

Q1 of company A = 2.5

Q3 of company A = 8

Interquatile range = (Q3 - Q1)/2 = (8 - 2.5)/2 = 5.5/2 = 2.75

Q1 of company B = 2

Q3 of company B = 5.5

Interquatile range = (5.5 - 2)/2 = 3.5/2 = 1.75

Therefore, the interquartile range for Company A employees is 2 more than the interquartile range for Company B employees.
