WebThe partial correlation between academic performance and gender can be estimated as follows using these values if we assume that there is a relationship between the two. The partial correlation formula is: -0.2 = (0.4) - (0.6 * 0.5) This suggests that there is a moderately weak negative correlation between academic performance and gender, when ... WebNov 17, 2024 · However, before we calculate the Pearson correlation coefficient between two variables we should make sure that five assumptions are met: 1. Level of Measurement: The two variables should be measured at the interval or ratio level. 2. Linear Relationship: There should exist a linear relationship between the two variables. 3.
