Math Problem Statement
Result Details & Calculation
X Values ∑ = 804.3 Mean = 53.62 ∑(X - Mx)2 = SSx = 15194.724
Y Values ∑ = 16907.5 Mean = 1127.167 ∑(Y - My)2 = SSy = 199520070.413
X and Y Combined N = 15 ∑(X - Mx)(Y - My) = 1614964.21
R Calculation r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))
r = 1614964.21 / √((15194.724)(199520070.413)) = 0.9275
Meta Numerics (cross-check) r = 0.9275 What is the correlation coefficient without the outlier? rwo =
