Webb9 dec. 2024 · The reason for this is simple: the statistic we are calculating the p-value and confidence interval for is for the absolute difference: δabs = (PB – PA), while the claims are for the relative difference: δrel = (PB – PA) / PA or the percentage change δrelPct = (PB – PA) / PA x 100 . The division by PA adds more variance to δrel and ... Webb10 dec. 2000 · The strength of the relationship between X and Y is sometimes expressed by squaring the correlation coefficient and multiplying by 100. The resulting statistic is known as variance explained (or R 2 ). Example: a correlation of 0.5 means 0.5 2 x100 = 25% of the variance in Y is "explained" or predicted by the X variable.
