When the data from two samples are statistically independent, the two-sample t-test is employed, while the paired t-test is used when the data is in the form of matched pairs.
The paired two-sample mean test is a statistical method used to determine whether or not pairs of samples have the same means. This test can be used in many fields of study, including psychology, sociology and economics.
When we want to compare the differences between two variables for the same subject, we utilise a paired t-test. The two variables are frequently separated by time. For example, we have cholesterol levels in 1952 and cholesterol levels in 1962 for each participant in the Dixon and Massey data set.
The test helps you identify the most popular topics and keywords in your niche, and it also helps you find out what type of content people are searching for on Google. It also helps determine how well your content performs in search engines and social media.
