#1

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


#2

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.
