There are many ways to determine if there is a linear relationship between two data sets. One way is to use a scatter plot. If the data points on the scatter plot fall along a line , then there is a linear relationship between the data sets. Another way to determine if there is a linear relationship is to use a correlation coefficient. If the correlation coefficient is close to 1, then there is a linear relationship between the data sets.

To test the accuracy of your spam email predictive model, you can use a holdout dataset or cross-validation. With a holdout dataset, you would split your data into a training set and a test set. You would train your model on the training set and then evaluate it on the test set. With cross-validation, you would split your data into a number of folds . For each fold, you would train your model on the training data and then evaluate it on the test data. You can then average the accuracy of your model across all the folds.
