Remarks
Student's t distribution is commonly used to test if the difference between the means of two samples is statistically significant. It is a variation of the normal distribution that takes into account that the mean of a sample is only an estimate for the mean of the population.
The student t distribution has one parameter: the degrees of freedom of the sample.
