Question

Jesse asked how many magazine subscriptions each

Answer 1

Answer:

Interquartile range of the data is:

IQR = 2

Step-by-step explanation:

First lets rearrange the data in ascending order:

0, 0, 0, 1, 1, 1, 1, 2, 2, 2, 3, 4, 4

Find Median:

Median = (No. of terms +1) / 2      (when n = odd number)

Median = 14/2 (th term)

Median = 7th term

Median = 1

Find Upper and Lower Medians:

As the number of total terms is odd (n=13) , we omit the median and form upper and lower sets and find their medium

0, 0, 0, 1, 1, 1, 1, 2, 2, 2, 3, 4, 4

Remove the median

0, 0, 0, 1, 1, 1    |    2, 2, 2, 3, 4, 4

Calculate the median of lower portion

0, 0, 0, 1, 1, 1

For even numbers

Lower Median = (0+1)/2

Lower Median = 0.5

Calculate the median of upper portion

2, 2, 2, 3, 4, 4

Upper Median = (2+3)/2

Upper Median = 2.5

Interquartile Range:

It is the difference between Upper and Lower Median

IQR = 2.5 - 0.5

IQR = 2
