When writing regression formulae, which of the following refers to the predicted value on the dependent variable (DV)?
|
|
Y
|
|
|
Y (hat)
|
|
|
X
|
|
|
X (hat)
|
|
|
a
|
Explanation:
Detailed explanation-1: -c) The predicted value of Y for the average X value.
Detailed explanation-2: -We can use the regression line to predict values of Y given values of X. For any given value of X, we go straight up to the line, and then move horizontally to the left to find the value of Y. The predicted value of Y is called the predicted value of Y, and is denoted Y’.
Detailed explanation-3: -Therefore, the formula for calculation is Y = a + bX + E, where Y is the dependent variable, X is the independent variable, a is the intercept, b is the slope, and E is the residual. Regression is a statistical tool to predict the dependent variable with the help of one or more independent variables.
