In statistics, it is imperative to arrange your data entries from least to greatest. That would be the first step of our solution
3 6 7 9 10 12 13
Interquartile range is the difference of the last quartile to the first quartile. Divide your entire data set into four parts. Each division is called a quartile. Its numerical value is the average of its numbers. However, since our data set contains 7 numbers, which is odd, we write the median (middle value) twice. The quartiles are:
3 6 | 7 9 | 9 10 | 12 13
Q₁= (3+6)/2 = 4.5
Q₂ = (7+9)/2 = 8
Q₃ = (9+10)/2 = 9.5
Q₄ = (12+13)/2 = 12.5
The interquatile range is Q₄ - Q₁ = 12.5 - 4.5 = 8
