Step 1
The shape of a t distribution changes with degrees of freedom (df). As the degrees of freedom increases the shape of the t distribution will begin to look similar to that of a normal distribution.
Step 2
However, the t distribution has more variability than a normal distribution, especially when the degrees of freedom are small. When this is the case the t distribution will be flatter and more spread out than the normal distributions.
