i. The technique used to measure the strength of the relationship between two sets of variables using the coefficient of correlation and the coefficient of determination is called regression analysis. 
ii. In order to visualize the form of the regression equation, we can draw a scatter diagram.
Iii) A line found using the least squares principle is the best-fitting line because the sum of the squares of the vertical deviations between the actual and estimated values is minimized.
A) (i), (ii) and (iii) are all correct statements
B) (i) and (ii) are correct statements, but not (iii).
C) (i) and (iii) are correct statements but not (ii).
D) (ii) and (iii) are correct statements but not (i).
E) All statements are false

Quizplus · Accepted Answer

Statement (i) is incorrect because the technique described is correlation analysis, not regression analysis. Statements (ii) and (iii) are correct as they accurately describe the use of scatter diagrams and the least squares principle in regression analysis.
