WebThe t test is one type of inferential statistics. It is used to determine whether there is a significant difference between the means of two groups. With all inferential statistics, we assume the dependent variable fits a normal distribution. When we assume a normal distribution exists, we can identify the probability of a particular outcome. WebThe t.test function can operate on long-format data like sleep, where one column ( extra) records the measurement, and the other column ( group) specifies the grouping; or it can operate on two separate vectors. By default, t.test does not assume equal variances; instead of Student’s t-test, it uses the Welch t-test by default.
