When to use t-distribution instead of normal distribution?

WebJun 7, 2015 · The t -distribution is used as an alternative to the normal distribution when sample sizes are small in order to estimate confidence or determine critical values that an observation is a given distance from the mean. It is a consequence of the sample standard deviation being a biased or underestimate (usually) of the population standard deviation.
