The dependent variable in linear regression is referred to by specific terms. The regressand (i) and the explained variable (iii) are both alternative names for the dependent variable (y). In contrast, the regressor (ii) and the explanatory variable (iv) denote the independent variables (x) used to predict or explain y.

Explanation:
In linear regression analysis, the dependent variable (usually denoted by y) is also known as:

(i) The regressand: This is an alternative name for the dependent variable, which is the variable being predicted or explained by the independent variables.

(iii) The explained variable: This term also refers to the dependent variable, as it is the variable that is being explained or predicted by the regression model.

On the other hand:

(ii) The regressor: This term refers to the independent variable (usually denoted by x), which is used to predict or explain the dependent variable.

(iv) The explanatory variable: This is another name for the independent variable, as it is the variable that provides an explanation or prediction for the dependent variable.

Therefore, the correct answer is B, which includes only (i) The regressand and (iii) The explained variable as alternative names for the dependent variable in linear regression analysis.		 B

In linear regression analysis, the dependent variable (usually denoted by y) is also known as the regressand and the explained variable. The terms "regressor" and "explanatory variable" refer to the independent variables (usually denoted by x).		 B
