Certain properties of the t distribution are as follows:
• The t distribution is bell-shaped and symmetrical. The total area under a t-curve is 1 or 100%
• The mean, median and mode of the t distribution are all equal to zero.
• As the degrees of freedom increases, the shape of the t distribution approaches to the standard normal distribution.
