Ever heard about unequal variance in t-test homework? You may wonder how you can handle this type of variance in the t-test. Let me give you some tips on how to tackle this situation and achieve your objective. One of the basic steps is to remove the heteroskedasticity (HSE) from the data. HSE refers to the situation where the standard deviation of your data varies widely across observations. In practice, this usually occurs in situations where you have repeated measurements, where we can’t assume that the variances are constant

The sample size and the distribution of the dependent variable are the same for both the groups. The sample size for the first group is 30, and the distribution of the dependent variable is normally distributed. Consequently, the t-test has a significant difference between the mean value of the first group and that of the second group (p < .05). Thus, the second group has a significantly different mean value from that of the first group. Now, I have one more thing to say: So, in summary, the t-test is a powerful tool

“You have just completed a statistical analysis on your t-test results and noticed that your t-statistic values are significantly different from 0.90 and 4.35, indicating a significant difference between the mean of the two populations. see here What happens now? Well, you know that a t-test with unequal variance will only provide statistical significance for one population. That is, the population in which the mean lies will be affected by the difference between the two t-statistics. You might wonder why. Well, remember that the null hypothesis was that the two populations are

In the T-test, the degrees of freedom, which refers to the number of different values that we are comparing (e.g., the 12 values for the mean). Different numbers of degrees of freedom have different significance levels (F = r squared), and unequal variance can cause discrepancies in those significance levels. For example, in comparing the mean for two independent samples, with 5 degrees of freedom, we could have: F = 5 / 12, with 95% significance level. We would expect the result to be
