Comparison of Beta Density Functions

Applet Exercise Use the applet Comparison of Beta Density Functions to compare beta density functions with (α = 2, β = 2), (α = 3, β = 3), and (α = 9, β = 9).

a What are the means associated with random variables with each of these beta distributions?

b What is similar about these densities?

c How do these densities differ? In particular, what do you observe about the “spread” of these three density functions?

d Calculate the standard deviations associated with random variables with each of these beta densities. Do the values of these standard deviations explain what you observed in part (c)?  Explain.

e Graph some more beta densities with α = β. What do you conjecture about the shape of beta densities with α = β?
