Question

Accepted Answer

T-test is a statistical test used to determine if there is a significant difference between the means of two groups.

T-test is used to compare the means of two groups to see if they are significantly different.
Assumptions for t-test include normal distribution of data, independence of observations, and homogeneity of variances.
There are two types of t-tests: independent samples t-test and paired samples t-test.
T-distribution is similar to the normal distribution but with heavier tails, used when sample size is small or population standard deviation is unknown.
