WebA single sample t-test compares the mean (M) of a single sample of scores to a known or hypothetical population mean (µ).This means you need to input the value of your known … WebFirst, we need to identify the correct test statistic. Because we’re comparing one mean to a null value, we need to use a 1-sample t-test. Hence, the t-value is our test statistic, and the t-distribution is our sampling distribution. Second, we’ll calculate the test statistic. The t-value formula for a 1-sample t-test is the following:
WebThe test statistic is used to decide the outcome of the hypothesis test. The test statistic is a standardized value calculated from the sample. The formula for the test statistic (TS) of a population mean is: x ¯ − μ s ⋅ n x ¯ − μ is the difference between the sample mean ( x ¯) and the claimed population mean ( μ ). Weba one-sample t-test (to test the mean of a single group against a hypothesized mean); a two-sample t-test (to compare the means for two groups); or; a paired t-test (to check …
