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.

Edward B. Watters of Newberg, Oregon, points to a legal decision that also calls into question the traditional storyânamely, that the first digital computer was the ENIAC, a machine built in 1945 by J. Presper Eckert and John W. Mauchly of the Moore School of Electrical Engineering at the University of Pennsylvania :tanasoffâs Computer,â Scientific American, August 1988 [not online]. Atanasoffâs first computer was a 12-bit 2-word machine running at 60Hz wall-plug frequency and could add and subtract binary numbers stored in a regenerative memory using a logic unit built with seven triode tubes.
