Question

if n = 7, Sum of X = 104 , Sum of Y =67, sum of XY = 1078, sum of square of X = 1642 = and Sum of square of Y = 713 . Find coefficient of correlation using karl's pearson​

Answer 1

Answer:

If n = 10, ∑ x = 50, ∑ y = - 30, ∑ x^2 = 290, ∑ y^2 = 300, ∑ xy = - 115 , then find the coefficient of correlation.

Answer 2

If n=10,∑x=50,∑y=−30,∑x2=290,∑y2=300,∑xy=−115, then find the coefficient of correlation.
