Question

Explain how to find the IQR

Answer 1

IQR?

Answer 2

interquartle range

Answer 3

Do you have data for a specific example?

Answer 4

know that's the question

Answer 5

ok so do you know

Answer 6

Consider the following data set:
{3, 4, 4, 5, 6, 7, 9, 11, 11, 12, 14, 15}
The median is the value half way between the two values either side of the middle:
\[median=\frac{7+9}{2}=8\]
The data can be partitioned into subsets, each with 6 members:
{3, 4, 4, 5, 6, 7} and {9, 11, 11, 12, 14, 15}
The Lower Quartile is the median of the first of these two subsets,
\[LQ=\frac{4+5}{2}=4.5\]
and the Upper Quartile is the median of the other subset,
\[UQ=\frac{11+12}{2}=11.5\]
The Interquartile Range is the difference between the Upper and Lower Quartiles:
IQR = 11.5 - 4.5 = 7

Answer 7

ok thanks
