Anscombe's Quartet is the modal example to demonstrate the importance of data visualization which was developed by the statistician Francis Anscombe in 1973 to signify both the importance of plotting data before analyzing it with statistical properties.

Usually people believe “the numerical calculations are exact, but graphs are rough” even though it’s completely wrong. Even I was not right about it before learning data analytics.

If you are new in the data science or its sub fields, believe me this is the first step towards the understanding of the importance of Data Visualization along with the statistics result.

Four Data-sets

Apply the statistical formula on the above data-set,

Average Value of x = 9

Average Value of y = 7.50

Variance of x = 11

Variance of y =4.12

Correlation Coefficient = 0.816

Linear Regression Equation : y = 0.5 x + 3
