We create a scatter plot of the data in regression analysis in order to visually check for a relationship between X and Y. This allows us to see if there is a linear relationship between the two variables, which is necessary for regression analysis. The scatter plot can also help identify outliers and patterns in the data, which can affect the accuracy of the regression analysis. The other choices (A, B, and D) are not the primary reason for creating a scatter plot in regression analysis.
