How to fill out application of t test
01
To fill out an application of t test, follow these steps:
02
Determine if your data meets the assumptions of the t test. The assumptions include normality of the data and equal variances between groups.
03
State your null and alternative hypotheses. The null hypothesis typically assumes no difference between the means of the groups, while the alternative hypothesis assumes there is a difference.
04
Choose the appropriate type of t test based on the design of your study. Common types include independent t test, paired t test, or one-sample t test.
05
Collect your data for each group or sample being compared. Make sure the data is accurately recorded and organized.
06
Calculate the relevant test statistic, which is usually the t value. This can be done using statistical software or by using formulas.
07
Determine the degrees of freedom for your test. This depends on the sample size and the type of t test being used.
08
Find the critical value for your desired significance level and degrees of freedom. This can be done using a t distribution table or statistical software.
09
Compare the calculated test statistic to the critical value. If the calculated t value is larger than the critical value, reject the null hypothesis. Otherwise, fail to reject the null hypothesis.

Interpret the results of your t test and draw conclusions based on the hypothesis testing.
11
Report the findings of your t test, including the test statistic, degrees of freedom, p-value, and conclusion.
