The t test is a way to tell if the difference between before and after results is significant or if those results could have happened by chance.... analysis on the data (for example, a t-test or ANOVA) which gives us a value known as a test statistic. This test statistic is then compared to a known distribution of values of that statistic that enables us to work out how likely it is to get the value we have if there were no effect in the population (i.e. if the null hypothesis were true). If it is very unlikely that we would get a test

One Sample T Test… as in the following picture, and the One-Sample T Test dialog box will appear on the screen. Select the variable “weight” to be analyzed into the Test Variable box, and enter the Test Value which the average value to be tested with (the mean value specified in the null hypothesis, that is 140 in this example). Click Continue and click OK for performing the test and

- Instructions For each of the problems below, provide the following: (a) Identification of which statistical test should be used (b) Written null hypothesis
- A t-statistic is necessary because the population standard deviation, defined as the measure of variability in a population, is not known for a small sample. T-statistics, on the other hand, allow for the use of the sample standard deviation, or s, which measures a specific sample's variation, and is more applicable to smaller-sized samples.
- • To calculate: Administer the same test to the same participants on two different occasions. Correlate the test scores of the two administrations of the same test.
- The p-value is calculated using the sampling distribution of the test statistic under the null hypothesis, the sample data, and the type of test being done (lower-tailed test, upper-tailed test, or two-sided test).
