The t distribution has relatively more scores in the tails.
true
The blue distribution.
false
The red distribution.
Use the demonstration to see the difference in shape between the t and normal distributions.
The difference between the t and normal distribution is greater with 3 degrees of freedom than with 50 degrees of freedom.

The greater the degrees of freedom the more similar the t and normal distributions.

Using the demonstration, change the degrees of freedom and see how it affects the similarity of the distributions.
In order to contain 95% of the distribution, you have to go out farther from the mean for a

The t distribution has relatively more scores in the tails so you must go out further.
