How do you find the correlation of n equals 15 Σxi equals 1293 Σyi equals 48.58 Σxiyi equals 4226.2 sx equals 6.9714 and sy equals 0.4236?
To find the correlation coefficient ( r ), use the formula: [ r = \frac{n \cdot \Sigma x_i y_i - \Sigma x_i \cdot \Sigma y_i}{\sqrt{(n \cdot \Sigma x_i^2 - (\Sigma x_i)^2)(n \cdot \Sigma y_i^2 - (\Sigma y_i)^2)}} ] Given ( n = 15 ), ( \Sigma x_i = 1293 ), ( \Sigma y_i = 48.58 ), ( \Sigma x_i y_i = 4226.2 ), ( s_x = 6.9714 ), and ( s_y = 0.4236 ), first calculate ( \Sigma x_i^2 ) and ( \Sigma y_i^2 ) using the relation ( s_x^2 = \frac{\Sigma x_i^2}{n} - \left(\frac{\Sigma x_i}{n}\right)^2 ) and ( s_y^2 = \frac{\Sigma y_i^2}{n} - \left(\frac{\Sigma y_i}{n}\right)^2 ). After obtaining these values, substitute them into the formula for ( r ) to find the correlation coefficient.
