Characteristics of t-distribution

1.       It is bell-shaped.

2.       It is symmetrical about the mean.

3.       The mean, median and mode are equal to 0 and are located at the center of the distribution.

4.       The curve never touches the x-axis.

5.       The variance is greater than 1.

6.       The t-distribution is actually a family of curves based on the concept of degrees of freedom, which is related to sample size.

7.       As the sample size increases, the t-distribution approaches the standard normal distribution.
