Understand that the t-test is a statistical hypothesis test used to determine if there is a significant difference between the means of two groups or samples.
Recall that the t-test compares the observed difference between sample means relative to the variability in the data, helping to infer if the difference is likely due to chance.
Recognize that the t-test is not designed to test the variance of a population, proportions, or correlations directly, but specifically focuses on comparing means.
Identify that the key concept behind the t-test is assessing whether the difference between two sample means is statistically significant.
Therefore, the t-test is principally a test of the difference between two means.
