- "In this video, we will use Microsoft Excel to perform a dependent t-test, also known as the paired t-test or paired-samples t-test. This statistical test compares the means of two related groups to determine if there is a significant difference between them. The dependent t-test is often used when we are interested in the difference between two variables measured on the same subjects, such as when the variables are separated by time or are measured under different conditions. Using Excel, we will calculate the p-value, which represents the probability of obtaining the observed difference between the means if there is actually no difference between the two groups. If the p-value is less than a predetermined level of statistical significance, we can conclude that there is a significant difference between the means of the two groups."
