Question
Which of these values could possibly be telling us about Cronbach’s alpha?
- 0.83
- 0.76
- 1.25
- A p value is required to be certain
Solution
Cronbach’s alpha is a measure of internal consistency or reliability of a set of scale or test items. It typically ranges from 0 to 1.
Let's evaluate each of the given values:
- .83: This value is within the range of 0 to 1, and it is a common value for Cronbach’s alpha, indicating good internal consistency.
- -.76: This value is negative, which is unusual for Cronbach’s alpha. While theoretically possible, a negative value often indicates a problem with the data, such as items that are not positively correlated.
- 1.25: This value is greater than 1, which is not possible for Cronbach’s alpha. Cronbach’s alpha cannot exceed 1.
- A p value is required to be certain: This statement is incorrect in the context of Cronbach’s alpha. Cronbach’s alpha does not require a p value for interpretation; it is a descriptive statistic.
Therefore, the value that could possibly be telling us about Cronbach’s alpha is .83.
