Question: State which of the following statement(s) is/are true. Steps to derive 1 Regression analysis is a mathematical measure of the average relationship between two or more variables in terms of the original units of the data. So, statement I is correct.2 In regression analysis there are two types of variables. The variable whose value is influenced or is to be predicted is called dependent variable and the variable which influences the values or is used for prediction is called the independent variable. Independent variable is also known as regressor or predictor or explanatory varaible while the dependent variable is also known as regressed or explained variable. So, statement II is correct.3 The line of regression is the line which gives the best estimate to the value of one variable for any specific value of the other variable. Then the line of regression is the line of "best fit". So, statement III is correct.4 There are always two lines of regression, one of y x x y y x y x 5 So, all the statements are correct.Hence the right answer is Option A Click Here To Go Back Simplify: 15⋅15..
