Dependent samples t-test compares the means of two related sample groups to determine if there is a statistically significant difference between them. It is used when observations in one sample group are known to be related to observations in the other sample group, such as when the same individuals are measured under two different conditions. The dependent samples t-test determines if any changes between the two conditions are likely due to chance or represent a real difference.

2. What is dependent samples t-test?
• Dependent samples t-test is conducted when the
observations of one sample group is known to be
related in some way to the other observations of sample
group. So typically, dependent sample t-test compares
