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.
ENIAC was built in the Moore School of Electrical Engineering of the University of Penn. Designed and built under the supervision of John Mauchly and J. Presper Eckert.

Though ENIAC was designed and primarily used to calculate artillery firing tables for the United States Army 's Ballistic Research Laboratory, its first programs included a study of the feasibility of the hydrogen bomb. When ENIAC was announced in 1946, it was heralded in the press as a Giant Brain.. It had a speed on the order of one thousand (10 3) times faster than that of electro-mechanical machines; this computational power, coupled with general-purpose programmability, excited scientists and industrialists alike.
