Conducting a Pearson Correlation Three assumptions are taken when conducting a Pearson Correlation: (1) there is random distribution in the pair of samples under comparison (2) there is independence of samples in each case to be compared and (3) there is normal distribution of the two samples to be compared. In regard to this, the third assumption i.e. samples were randomly distributed was violated. This is in view of the fact that Howell, Huessy, and Hassuk (1985) clearly stated that the samples in their study were not obtained randomly. Otherwise, the first and second assumptions were met i.e. each case forming the pair to be compared were independent of each other and there was normal distribution of sample pairs to be compared from the fact that the samples were more than 30, i.e. the sample size was large. In this study, three variables were used to perform a 2-tailed Pearson Correlation with significance being considered at the 0.01 level. The variables were: ADD-like behaviour score (mean of 3), IQ Score and GPA in 9th Grade.
