The term that indicates the degree of correlation between two variables is correlation coefficient. In the context of the provided answer choices, the most appropriate answer is R-squared.

Explanation:

1. Degree of Slope: This typically refers to the slope of a line in a linear regression model, which indicates how much the dependent variable changes with a one-unit change in the independent variable. It does not measure the correlation directly.

2. Correlation Constant: While this term is sometimes used to refer to correlation coefficients, it is not standard terminology like "correlation coefficient" or "R-squared."

3. Slope Coefficient: Similar to degree of slope, this term refers to the coefficient representing the slope of the regression line and not the strength or degree of correlation.

4. R-squared: This is a statistical measure that represents the proportion of the variance for a dependent variable that's explained by an independent variable(s) in a regression model. It indicates the strength of correlation, making it the right choice for this question.

5. X-squared: This term is not relevant in the context of correlation between variables.

Therefore, the correct answer is R-squared.
