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.

Started in 1943, the ENIAC computing system was built by John Mauchly and J. Presper Eckert at the Moore School of Electrical Engineering of the University of Pennsylvania. Because of its electronic, as opposed to electromechanical, technology, it is over 1,000 times faster than any previous computer. ENIAC used panel-to-panel wiring and switches for programming, occupied more than 1,000 square feet, used about 18,000 vacuum tubes and weighed 30 tons.
