When to use the t test in statistics?

The t-test can be used to determine if two sets of data are significantly different from each other. The t-test is most commonly applied when the test statistic would follow a normal distribution if the value of a scaling term in the test statistic were known.

Which is the null hypothesis in a t test?

You can test the difference between these two groups using a t-test. The null hypothesis (H 0) is that the true difference between these group means is zero. The alternate hypothesis (H a) is that the true difference is different from zero. What type of t-test should I use?

What is a statistic in a test statistic?

When to use a paired or two sample t test?

If you are studying one group, use a paired t-test to compare the group mean over time or after an intervention, or use a one-sample t-test to compare the group mean to a standard value. If you are studying two groups, use a two-sample t-test. If you want to know only whether a difference exists, use a two-tailed test.
