The correlation coefficient, denoted by r, measures the strength and direction of a linear relationship between two variables. Its value is always within a specific range. The fundamental property of the correlation coefficient r is that its value must always be between -1 and 1, inclusive. -1 r 1 This means that r cannot be less than -1 and cannot be greater than 1. To determine which specific expression is false, the list of expressions needs to be provided. However, any expression that states r is outside the range of [-1, 1] would be false. For example, an expression like r = 1.2 or r = -1.5 would be false. Similarly, an expression stating that r^2 < 0 would also be false, as r^2 must always be non-negative and between 0 and 1. 3 done, 2 left today. You're making progress.
