The t distribution for df = 4 is flatter and more spread out than the t distribution for df = 20.

Question

Quizplus · Accepted Answer

This statement is true. As the degrees of freedom (df) in the t distribution increase, the distribution becomes more and more normal, resembling the standard normal distribution (with a mean of 0 and standard deviation of 1). Therefore, with fewer degrees of freedom (df = 4), the t distribution is more spread out and flatter than with more degrees of freedom (df = 20).

The T Distribution for Df = 4 Is Flatter and More
