Chapter Five Terminology
Uniform Distribution - A continuous random variable where all its values are spread evenly over the range of probabilities. The graph of the distribution has a rectangular shape.

Density Curve - The graph of a continuous random variable that satisfies the following two properties:
1. The total area under the curve must equal 1.
2. Every point on the graph must a vertical height that is 0 or greater.

Normal Distribution - The graph of a continuous random variable that is symmetric and bell-shaped. Much of everyday phenomenon can be approximated by normal distribution. People's heights and weights, ACT scores, and the stock market are just a few examples of everyday occurrences that can be modeled by a normal distribution.

Standard Normal Distribution - A normal probability distribution with a mean of 0 and a standard deviation of 1.

Sampling Distribution of the Mean - A probability distribution of the sample means, with all samples having the same sample size.
