From the data given below, calculate Karl Pearson’s coefficient of correlation between density of population and death rate by step deviation method.

First of all, we shall compute density of population i.e., population per sq km and death rate per 1000.

Density of Population=Population/Area, Death Rate =Number of Deaths/Population x 1000

Calculation of Coefficient of Correlation

There is high degree of positive correlation between density of population and death rate.
