When to t test z test t interval z interval etc?

Use a t-test when comparing the means of two groups, especially when the sample size is small (n < 30) and the population standard deviation is unknown. A z-test is appropriate for large sample sizes (n ≥ 30) or when the population standard deviation is known. For confidence intervals, use a t-interval for smaller samples with unknown population standard deviation, and a z-interval for larger samples or known population standard deviation. Always check if the data meets the assumptions for each test before proceeding.


When is a t-test performed instead of a z-test?

A t-test is performed instead of a z-test when the sample size is small (typically n < 30) and the population standard deviation is unknown. The t-test accounts for the increased variability and uncertainty in small samples by using the sample standard deviation rather than the population standard deviation. Additionally, it is often used when the data is approximately normally distributed.
