T-test:It is based on t-distribution and is considered an appropriate test for judging the significance of sample mean etc. when population variance is not known.
X2-test:It is based on chi-square and as a parametric test is used for comparing a sample variance to a theoretical population variance is unknown.
F-test:It is based on f-distribution and is used to compare the variance of the two-independent samples.
