Question

The table below shows the number of hours some business people in two states spend in meetings each week

State B
24 22 20 23 23 50 20 46 21
Create a five-number summary and calculate the interquartile range for the two sets of data.

Answer 1

start by putting the numbers for each group in order

Answer 2

21 22 22 23 23 23 24 24 25 A
20 20 21 22 23 23 24 46 50 B
now what

Answer 3

these are the 5 numbers you're looking for in each group.
minimum → lowest number
1st quartile → median of the lower half of numbers
median → middle number
3rd quartile → median of the higher half of the numbers
maximum → highest number
Which ones do you know how to find?

Answer 4

helpp

Answer 5

I don't know how to do it

Answer 6

can you pick out the maximum and minimum in group A

Answer 7

21 25

Answer 8

right. now pick out the median. what number is in the middle of group A?

Answer 9

use the list you wrote in order to pick it out

Answer 10

23

Answer 11

yes that's right. now for the 1st quartile look at the numbers left of the median.
They are 21, 22, 22, and 23. We need to find their median. Since it's an even amount of numbers, there you can't just pick it out. We have to add the 2 middle numbers and divide by 2.

1st quartile = (22 + 22)/2 = 22

Answer 12

Does that make sense?

Answer 13

yes

Answer 14

great. so for the 3rd quartile you need to look at the numbers right of the median. So what is the median of 23, 24, 24, and 25?
