Differences Between Paired Sample T-Tests and Independent Sample T-Tests
When we want to compare the means of two data groups, we often use a difference test. The most commonly used difference test is the t-test. In a t-test, the samples being compared can be either paired or independent.
Understanding the t-test for non-normally distributed data
For researchers aiming to explore the differences between two sample groups, the t-test is a viable option. According to theory, the t-test can determine differences between two sample groups, whether they are paired or independent.
How to Choose Regression, Correlation, or Difference Test for Variable Association Analysis
Selecting the appropriate analysis method will prevent errors in concluding research results. There are various methods of data analysis that researchers can choose from. The selection of data analysis methods depends on the research objectives and the characteristics of the collected data.
The Effectiveness of the New Learning Method using Paired Sample t-Test
The effectiveness of a new method can be tested using paired sample t-test. The paired sample t-test was chosen due to using the same sample before and after using the new method.
