Answer 2

In Statistics,Karl Pearson's coefficient of correlation or simply,Pearson's coefficient correlation measures the strength of linear relationship or association between two variables.

Explanation:

Note that Pearson's correlation basically measures how strong or prominent the linear relationship is between any two variables.It shows whether the variables has any strong or convincing correlation.As an example,suppose,we are interested to examine the relationship between how many people you are going to the bar with and how much you enjoy in the bar.Therefore,the main focus of analysis is on the connection/relationship between number of people and enjoying at the bar.Therefore,Pearson coefficient correlation in this case,will measure the statistical relationship between the number of people you are taking along at the bar and the level of personal enjoyment.However,it does not explain other factors that might affect your personal enjoyment at the bar such as your budget,ambiance,taste of the drinks and food and so forth.
