True or False? A high correlation between two variables in a scatter chart is a good way to show that the Independent Variable causes the Dependent Variable.
True
False
Homework Answers
Answer:
False
Explanation:
Although scatter chart shows a high correlation between two variables, this does not mean that the independent variable causes the dependent variable. We know that the correlation does not always imply the causation, but causation always implies correlation.

serial correlation happens when: There is high correlation between the consequent error terms of the regression. There is high correlation between two or more of the independent variables. There is high correlation between some of the independent variables and the error terms. There is high correlation between the dependent variable and the error terms.

True or False 1. The correlation coefficient is way to determine if one variable causes another variable to change. 2. A linear model is representation of the linear relationship between two variables. 3. The least squares line, or line of best fit, is the line which minimizes the sum of the individual squares of the residuals. 4. Most linear models do not have any residuals. 5. Regression equations can be used to make predictions. However, the context of the data...

QUESTION 6 Suppose the correlation coefficient between two variables is found to be -0.94. Which of the following statements are true? there is a strong tendency for small values of one variable to be associated with large values of the other variable there is a weak negative relationship between the variables a scatter plot of the data points would show a clear downward trend there is a strong tendency for low values of one variable to be paired with low...

8) Suppose the correlation coefficient between two variables is -0.897. Does the dependent variable increase or decrease as the independent variable increases? O a. The dependent variable will decrease as the independent variable increases. O b. The dependent variable will remain constant as the independent variable increases. The dependent variable will remain constant as the independent variable increases. The dependent variable will increase as the independent variable increases.
