Identifying a Model and R2 Different samples are collected, and each sample consists of IQ scores of 25 statistics students. Let x represent the standard deviation of the 25 IQ scores in a sample, and let y represent the variance of the 25 IQ scores in a sample. What formula best describes the relationship between x and y ? Which of the five models describes this relationship? What should be the value of R2?
