What is a t-test?
a t test is used inplace of a z-test when the population standard deviation is unknown.
Is a t-test a parametric study?
Yes, it is. The one sample t-test is a study of the parameter population-mean. You can also use the t-test to test for the difference between two population means (both parameters).
What does a t-test tell you?
A t-test is an assessment of whether the means of two groups are statistically different from one another (running a t-test is appropriate when you want to compare the means of two groups). A t-test tell you the probability that those two sets of values come from different groups.
Is Paired samples T-test an example of nonparametric tests?
A paired samples t-test is an example of parametric (not nonparametric) tests.
What is a parametric test used to compare the means of two groups?
t-test
Is T test similar to Z test?
no t test is similar to z test because t test ie used for unknown observation and z is for the medicne
What is a t-test?
a t test is used inplace of a z-test when the population standard deviation is unknown.
What is the t test used for?
The"t" test, (called the "small 't' test, to distinguish it from the large 'T' test) is a test for deviation from a known norm, using a smaller sample set than the one required by the large T test. It is said to have been developed by the head of quality control at the Guinness Brewery in Ireland.
Is a z test or t test used more often?
t test, because the z test requires knowing the population standard deviation and that's rare. The t test embodies an estimate of the standard deviation.
Is t-test a parametric test or not?
yes
What does the t and the c mean on the pregnancy test from the doctors?

Is a t-test a parametric study?
Yes, it is. The one sample t-test is a study of the parameter population-mean. You can also use the t-test to test for the difference between two population means (both parameters).
Why do you use the t test for the independent sample?
Because under the null hypothesis of no difference, the appropriate test statistic can be shown to have a t-distribution with the relevant degrees of freedom. So you use the t-test to see how well the observed test statistic fits in with a t-distribution.
Difference scores are usually used with a. a t test for a single sample b. a t test for dependent means c. a t test for independent means d. all of the above?

How to test data using SPSS?
You can test data using T-Test in SPSS. Click Analyze > Compare Means > Independent-Samples T-Test to run an Independent Samples T-Test in SPSS. In the Independent-Samples T-Test window, you specify the variables to be analyzed. On the left side of the screen, you will see a list of all variables in your dataset.
