RESEARCH METHODOLOGY

Detailed explanation-1: -IQR is used to measure variability by splitting a data set into four equal quartiles. IQR uses a box plot to find the outliers. ‘’To estimating IQR, all the values form (sort) in the ascending order else it will provide a negative value, and that influences to find the outliers.”

Detailed explanation-2: -Order the data from least to greatest. Find the median. Calculate the median of both the lower and upper half of the data. The IQR is the difference between the upper and lower medians.
