Document Summary

Chapter 6: the normal curve, standardization and z scores. Normal curve: a specific bell-shaped curve that is unimodal, symmetric and defined mathematically. Standardization: converts individual scores from different normal distributions to a shared normal distribution with a known mean, standard deviation, and percentiles. Z score: the number of standard deviations a particular score is from the mean. Z distribution: a normal distribution of standardized scores. Standard normal distribution: a normal distribution of z scores. Central limit theorem: refers to how a distribution of sample means is a more normal distribution than a distribution of scores, even when the population distribution is not normal. Distribution of means: a distribution composed of many means that are calculated from all possible samples of a given size, all taken from the same population. The mean of the sample means will be the same as the mean. Standard error: the name for the standard deviation of a distribution of means.
