Which of the following values could not represent a correlation coefficient? Select one:

C. 0
D. 0.927


Sagot :

In order to determine which value could not represent a correlation coefficient, we need to understand the range of valid correlation coefficients. A correlation coefficient, often denoted as [tex]\(r\)[/tex], measures the strength and direction of the linear relationship between two variables. It ranges between -1 and 1 inclusive.

Here are the steps to determine the invalid value among the provided options:

1. Understand the Range: The correlation coefficient must lie within the range [tex]\([-1, 1]\)[/tex]. This means any value less than -1 or greater than 1 cannot be a valid correlation coefficient.

2. Check Each Option:
- Option A: -1
- This value is exactly -1, which is within the acceptable range. So, it could be a valid correlation coefficient.
- Option B: 1.032
- This value is greater than 1, which exceeds the upper limit of the acceptable range. Therefore, it cannot be a valid correlation coefficient.
- Option C: 0
- This value is 0, which is within the range [-1, 1]. Hence, it could be a valid correlation coefficient.
- Option D: 0.927
- This value is greater than 0 and less than or equal to 1, which is within the acceptable range. Thus, it could be a valid correlation coefficient.

3. Conclusion:
- Among the given values, the value that cannot represent a correlation coefficient is 1.032, as it lies outside the range [tex]\([-1, 1]\)[/tex].

Therefore, the correct answer is Option B: 1.032.
