How do you enable the correlation coefficient on a calculator?

Back

Press 2nd Catalog, then select Diagnostic On, and press Enter twice.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the difference between correlation and causation?

Back

Correlation indicates a relationship between two variables, while causation indicates that one variable causes the other.

Front

What is the y-intercept of the line y = -3x - 3?

Back

The y-intercept is -3.

Front

How do you interpret the correlation coefficient value of -1?

Back

A correlation coefficient of -1 indicates a perfect negative linear relationship between two variables.
