C)Chi-square test
D)Significance test
E)none of the above

Question

Quizplus · Accepted Answer

The least squares procedure is used in regression analysis to find the line of best fit. It involves calculating the sum of the squared differences between the actual values and the predicted values, and finding the line that minimizes this sum. This line represents the relationship between the two variables that is the closest possible fit to the data. Other statistical tests such as Pearson's product-moment correlation and the chi-square test are not used for line fitting specifically.
