Answer:
By IQR , i hope you meant inter quartile range
Steps:
Step 1: Put the numbers in order.
[tex]2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7[/tex]
Step 2: Find the median.
[tex]2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7[/tex]
Step 3: Place parentheses around the numbers above and below the median. (it makes Q1 and Q3 easier to spot.)
[tex](2, 3, 3, 4, 4,) 4, (4, 5, 5, 6, 7)[/tex]
Step 4: Find Q1 and Q3
Think of Q1 as a median in the lower half of the data and think of Q3 as a median for the upper half of data.
[tex](2, 3, 3, 4, 4,) 4, (4, 5, 5, 6, 7)\\\\Q_{1} = 3 \ and \ Q_{3}= 5[/tex]
Step 5: Subtract Q1 from Q3 to find the interquartile range.
[tex]IQR =Q_{3}-Q_{1} =5-3=2[/tex]
