The correct answer is C. significance analysis.
Significance analysis is a statistical procedure used to determine whether the results of a study are statistically significant. This means that the results are unlikely to have occurred by chance. Significance analysis is often used in regression analysis to determine whether the relationship between two variables is statistically significant.
Weighted analysis is a statistical procedure used to give more weight to data points that are considered to be more reliable. This is often done in regression analysis when some data points are considered to be more accurate than others.
Average analysis is a statistical procedure used to calculate the average value of a set of data points. This is often done in regression analysis to calculate the average value of the dependent variable.
Specification analysis is a statistical procedure used to determine whether the model specification is correct. This means that the model is correctly specified and that the assumptions of the model are met.
In conclusion, the correct answer is C. significance analysis.
