independent variable relationship

There is a linear relationship between the dependent variable and the independent variables. This is called the ________ assumption. The independent variables are not correlated. This is called the _______ assumption. => nonmulticolinearit..

Which of the following statement(s) is/are false? I. The variances (or standard deviations) for the y variables are the same for each value of the independent variable. This is equal - variance assumption. II. There is a linear relationship between the depend..

The means of each group of a two-way analysis of variance for two independent variables are plotted as shown in the graph. What does the graph represent about the interaction of the variables? => Disordinal interaction or Ordinal interaction or No interaction..

Which of the following statement(s) is/are true? I. A relationship between two variables is called simple relationship. II. When both variables increase or decrease at the same time then that relationship is called negative relationship. I..

The means of each group of a two-way analysis of variance for two independent variables are plotted and shown in the three graphs. Which of these represents a disordinal interaction? Consider the interaction to be significant. => Both graph 1 and graph 2 or Graph 1 or Graph 3 or..

The cost of a taxi ride from Edd′s home to his office is a function of the number of miles between his home and office. Which of the following is the independent variable? => The driving time to the office or The cost of the taxi ride or The distance between Edd′s ho..

For any specific value of the independent variable, the values of the dependent variable y are normally distributed. This is called the __________ assumption. => independence or linearity or equal - variance or normality..

ax + b = 0 is a linear equation in one variable. Consider the equation 2x + 4 = 0 2x = -4 x = -2 Since this equation is independent of y, for all values of y, x = -2 Hence x = -2 is a line parallel to the y-axis at x = -2. Consider the equation y - 5 = 0 y - 5 = 0 y = 5 Since th..

State which of the following statement(s) is/are true. I. Regression analysis is a measure of the relationship between two variables. II. In regression analysis, there are two types of variables, regressor variable and regressed variable. III. The l..

Which of the following statement(s) is/are true? I. A multiple regression equation with three independent variables x 1 , x 2 and x 3 and one dependent variable would have the form y′ = a + b 1 x 1 + b 2 x 2 + b 3 x 3 . II. A multiple regression equation with two..
