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.

This was not a dream of science fiction, but a representation of ENIAC (Electronic Numerical Integrator Analyzer and Computer), the gigantic machine credited with starting the modern computer age. ENIAC, with its 17,468 vacuum tubes, 70,000 resistors, 10,000 capacitors, 1,500 relays, and 6,000 manual switches, was a monument of engineering -- and an energy hog.
