QuestionWhich of the following values could not represent a correlation coefficient? A. -1 B. 0 C. 0.927 D. 1.032

Studdy Solution

STEP 1

1. The correlation coefficient, denoted as $r$ , ranges from -1 to 1.
2. Any value outside this range is not a valid correlation coefficient.

STEP 2

1. Identify the valid range for correlation coefficients.
2. Check each option to determine if it falls within the valid range.

STEP 3

The valid range for a correlation coefficient $r$ is:
$-1 \leq r \leq 1$

STEP 4

Check each option:
- Option A: $-1$ is within the range $[-1, 1]$ . - Option B: $0$ is within the range $[-1, 1]$ . - Option C: $0.927$ is within the range $[-1, 1]$ . - Option D: $1.032$ is outside the range $[-1, 1]$ .
The value that could not represent a correlation coefficient is:
$\boxed{1.032}$
