Definition of T Distribution

The T distribution whose other name is also Student T Distribution is a probability distribution much similar to a normal distribution, the difference in these distributions is that the T distribution has a curve that is a bit short and stout. When you have less no. of samples then you use T distribution instead of normal distribution. If the no. of samples exceeds then the T distribution becomes more similar to normal distribution. Also, if the size of samples is more than 20 then the two distributions become almost the same.
