12.5: Testing the Significance of the Correlation Coefficient
WebCalculate the square of the difference for both the data sets X and Y. Correlation Coefficient is calculated using the formula given below: Correlation Coefficient = Σ [ (X – Xm) * (Y – Ym)] / √ [Σ (X – Xm)2 * Σ (Y – Ym)2] So it means that both the data sets have a positive correlation and is given by 0.343264. WebTo calculate R-squared, you need to determine the correlation coefficient and then square the result. R Squared Formula = r2 Where r the correlation coefficient can be calculated per below: r = n (∑xy) – ∑x ∑y / √ [n* (∑x2 – (∑x)2)] * [n* (∑y2 – (∑y)2)] You are free to use this image on your website, templates, etc., smallest sheep breed in uk
