The correlation coefficient is a measure that determines the direction and strength of the relationship between the two variables. The symbols r and Ï represent correspondingly the correlation coefficient of sample and population data. The value of correlation coefficient ranges from -1 to 1 both inclusive.

In 1946, John Mauchly and John Presper Eckert developed the ENIAC I (Electrical Numerical Integrator And Calculator). 1  The American military sponsored their research because they needed a computer for calculating artillery-firing tables, the settings used for different weapons under varied conditions for target accuracy.
