If two variables are highly correlated, what do you know?
Group of answer choices
that they always go together
that high values on one variable lead to high values on the other variable
that there are no other variables responsible for the relationship
that changes in one variable are accompanied by predictable changes in the other
If variables are highly correlated, in that case dependent variable can be predicted based on independent variable in the direction they are correlated (negative or positive)
So answer here is
that changes in one variable are accompanied by predictable changes in the other

When two explanatory variables are highly correlated, should you remove one of the correlated explanatory variables to reduce the multicollinearity problem. A. Yes, it will reduce the standard errors on the coefficients and increase the t statistics. B. No, it will not affect the t statistics on the coefficients. C. No, it will cause the coefficient on the remaining variable to be biased. D. Yes, it will improve the fit of the regression model.
Pearson's r measures what two components of a relationship between variables? Group of answer choices Strength and direction Predictions and real values Strength and magnitude Power and effect
List two variables that you could study the relationship between using a correlated groups t-test. For each variable, indicate if the variable is (1) the IV or DV, (2) nominal, ordinal, interval, or ratio, and (3) the values of each variable. Then briefly describe what makes it a within-subjects design.
Correlation coefficient tells you: Group of answer choices: which variable causes a change in another variable if there is a difference between groups nothing important the strength and nature of the relationship between two variables
1. A global variable is a variable that’s defined Group of answer choices within any block of code within any function outside of any function within a header file 2. Which of the following is/are differences between value variables and reference variables? Group of answer choices A value variable stores a copy of a value in memory, and a reference variable refers to a value that already exists in memory. Changing the value of a value variable doesn’t change the...

A research analyst states that the correlation between two variables is statistically significant from zero (with r = 0.85). Which of the following conclusion is appropriate? High values of one variable tend to be associated with low values of the other variable. For every unit of change in one variable tend to be associated with .85 values of the other variable. (C) Any association between the two variables does not appear to be linear. (D) 0.85 indicates...
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...
