On the other hand, if you have two groups and need to compare the means of two independent samples, you can use a two-sample t-test. If the groups happen to have paired observations, you could use apaired t-test. But how does one carry out t-tests? More importantly, how does one ...

Paired: Compares the means of matched pairs, such as before and after scores. In this post, you’ll learn about the different types of t tests, when you should use each one, and their assumptions. Additionally, I interpret an example of each type. ...
Ensure that your two data sets are both normally distributed or the results may not be valid. This can be checked using a Normality Test in SPSS to see if the data set fits a standard bell curve. Cite This Article MLA Perdue, Matthew. "How To Interpret An Independent T Test In SPSS"...

necessary parameters. Excel will then calculate the t-value and p-value for your data, which you can use to determine whether there is a significant difference between the two groups. Remember to interpret your results carefully and consider any limitations or potential sources of error in your ...
A Step-by-Step Guide on Setting Up an A/B Test in GA4 Before we start, it’s important to note that GA4 cannot run an A/B test by itself. For that, you need to use a third-party tool such as Optimizely or VWO. However, you can still interpret the results from your A/B test...
The tricky thing about t-values is that they are a unitless statistic, which makes them difficult to interpret on their own. Imagine that we performed a t-test, and it produced a t-value of 2. What does this t-value mean exactly? We know that the sample mean doesn’t equal the null...
