What is the dependent sample t-test?
The dependent sample t-test is a member of the t-test family. The dependent sample t-test is used when the observations or cases in one sample are linked with the cases in the other sample. This is typically the case when repeated measures are taken, or when analyzing similar units or comparable specimen.
What is the dependent variable in a t-test?
A Test Variable(s): The dependent variable(s). This is the continuous variable whose means will be compared between the two groups.
What type of relationship does a dependent t-test assess?
The dependent t-test (also called the paired t-test or paired-samples t-test) compares the means of two related groups to determine whether there is a statistically significant difference between these means.
What does an independent t-test tell you?
The independent t-test, also called the two sample t-test, independent-samples t-test or student’s t-test, is an inferential statistical test that determines whether there is a statistically significant difference between the means in two unrelated groups.
How do I report a dependent t-test?
Reporting the Output of the Dependent T-Test You might report the statistics in the following format: t(degrees of freedom) = t-value, p = significance level. In our case this would be: t(19) = -4.773, p < 0.0005.
What is dependent sample?
Dependent samples are paired measurements for one set of items. If the values in one sample affect the values in the other sample, then the samples are dependent. If the values in one sample reveal no information about those of the other sample, then the samples are independent.
How do I report t-test results?
The basic format for reporting the result of a t-test is the same in each case (the color red means you substitute in the appropriate value from your study): t(degress of freedom) = the t statistic, p = p value. It’s the context you provide when reporting the result that tells the reader which type of t-test was used.
