Given the 5 number summary, calculate the cutoff for the Low/left outlier. Round your answer to the nearest whole number.
-1, 10, 10, 15, 46
The 5 number summary consist minimum , Q1(1st quarter), Q2(Median) , Q3(3rd quarter), Maximum
Sp here
Minumum | Q1 | Q2 | Q3 | Maximum |
-1 | 10 | 10 | 15 | 46 |
Low / Left cutoff for outlier is
Q1 - 1.5 * IQR
Here IQR ( Interquartile range )= Q3 - Q1
= 15 - 10
IQR= 5
Low / Left cutoff = 10 - (1.5 * 5)
= 10 - 7.5
Low / Left cutoff = 2.5
