Sample Mean, A Formula

Sample Mean, A Formula. If X is any random variable, then, as n increases without bound, the distribution of its standardized sample mean, approaches the distribution of the standard normal random variable, Z, whose p.d.f . is This is called the Central Limit Theorem .

The Normal Probability Distribution

The Normal Probability Distribution. What is a distribution? A collection of scores, values, arranged to indicate how common various values, or scores are. Mean (population, sample) Standard deviation (population, sample) Median Mode. Scores in our class.
