WebAug 2, 2024 · Correlation analysis example You check whether the data meet all of the assumptions for the Pearson’s r correlation test. Both variables are quantitative and normally distributed with no outliers, so you calculate a Pearson’s r correlation coefficient. The correlation coefficient is strong at .58. WebThe restricted range for the Pearson correlation is especially unfortunate when you try to analyze the association between binary variables by using models developed for continuous data, such as factor analysis and principal component analysis. The tetrachoric correlation of two variables (Y 1;Y 2) can be thought of as the Pearson correlation goucher college gear
