Answer by CPhill(1959)   (Show Source):
You can put this solution on YOUR website! To determine if the assumption of equal variances was met, we need to look at Levene's Test for Equality of Variances.
* **Levene's Test:** This test checks if the variances of the two groups being compared are equal.
* **Sig. (Significance):** This is the p-value of Levene's Test.
In this case:
* F = 1.865
* Sig. = 0.173
**Interpretation:**
* If the Sig. value (p-value) is greater than 0.05, we fail to reject the null hypothesis of equal variances. This means we can assume equal variances.
* If the Sig. value (p-value) is less than 0.05, we reject the null hypothesis of equal variances. This means we cannot assume equal variances.
Since the Sig. value is 0.173, which is greater than 0.05, we fail to reject the null hypothesis.
**Answer:**
Yes, the assumption of equal variances was met.
