Linear regression is the appropriate method to use when one variable (years of education) is used to predict another variable (number of books read per year). It allows for the calculation of a regression line that predicts the value of the dependent variable (number of books read) given the value of the independent variable (years of education). Chi square is used to test for differences between observed and expected frequencies in categorical data, while Pearson's and Spearman's correlations are used to measure the strength and direction of the relationship between two continuous variables, but not to predict one variable based on another.
