The difference between the histogram of 175 behavior problem scores and a normal distribution is
A) the normal distribution is continuous, while behavior problem scores are discrete.
B) the normal distribution is symmetric, while behavior problem scores may not be.
C) the ordinate of the normal distribution is density, the ordinate for behavior problems is frequency.
D) Each of the previous choices is correct.

Question

Each choice correctly identifies a difference between a histogram of behavior problem scores and a normal distribution: A) highlights the difference between continuous and discrete data, B) points out potential asymmetry in real-world data versus the symmetric nature of a normal distribution, and C) distinguishes between density (used in continuous distributions) and frequency (used in histograms for discrete data).
