The document contains instructions for calculating Pearson's correlation coefficient from sample data and calculating multiple correlation coefficients from additional sample data. It provides data sets with marks in pharmacognosy and statistics, as well as data for variables X1, X2, and X3. The goal is to calculate the correlation coefficients and interpret the values.
