C) The same as a Type ll error
D) A measure of the validity of the data

The sum of squares is a statistical tool used to measure the variability of the data. It calculates the sum of the squared differences between each data point and the mean, and is used to determine the variance and standard deviation of a dataset. A Type l error refers to rejecting a true null hypothesis, while a Type ll error refers to failing to reject a false null hypothesis - neither of which are related to the sum of squares. The sum of squares is also not a measure of the validity of the data, as validity refers to whether a measurement tool is accurately measuring what it is intended to measure.
