Answer - C-Manipulated by the experimentor.
A variable is defined as anything that has a quality or quantity that varies.
Variables are of many types. The main divisions of variables are
-Independent variables
-Dependent variables
Independent variables are those which can be manipulated by the experimentor.
Dependent variables are those which is dependent on the independent variable and can't be manipulated by the experimentor. It varies based on the independent variable.

Which of the following is true? A.The predictive power of an independent variable comes from the level of correlation that it has with the dependent variable. B. If you have a variable with several categories like days of the week, there is no way that you can convert the categories to a quantitative variable. C. All of the answers on this list are true. If the p-value for an independent variable is lower than 0.05, then we should discard that...

Data from the 1993 World Almanac and Book of Facts were used to predict the life expectancy for men in a country from the life expectancy of women in that country. The resulting regression equation was Yˆ = 9.32 + 0.79(X). Using the regression equation, what would you predict...

For which of these research situations would you most likely calculate a correlation coefficient? A. independent variable = college major; dependent variable = type of car owned B. independent variable = age; dependent variable = reaction time in milliseconds C. independent variable = type of car owned; dependent variable = money spent on gasoline per week D. independent variable = city of residence; dependent variable = miles driven per week

If a correlation coefficient is 0.80, then: O A. The explanatory variable is usually less than the response variable. O B. The explanatory variable is usually more than the response variable O C. Below average values of the explanatory variable are more often associated with below-average values of the response variable. O D. Below average values of the explanatory variable are more often associated with above-average values of the response variable. O E. None of the statements are correct.

Regression and Multicollinearity When multiple independent variables are used to predict a dependent variable in multiple regression, multicollinearity among the independent variables is often a concern. What is the main problem caused by high multicollinearity among the independent variables in a multiple regression equation? Can you still achieve a high r for your regression equation if multicollinearity is present in your data? Regression and Multicollinearity When multiple independent variables are used to predict a dependent variable in multiple regression, multicollinearity...
