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.

The computer was based on some concepts developed by John Atanasoff, a physics teacher at Iowa State College. ENIAC was completed in 1945 and is regarded as the first successful, general digital computer. It weighed more than 27,000 kg (60,000 lb), and contained more than 18,000 vacuum tubes. Roughly 2000 of the computer's vacuum tubes were replaced each month by a team of six technicians.
