[MODULE 6-7] Central Limit Theorem & Percentiles and t-distribution

Central Limit Theorem

states that the sampling distribution of the mean approaches a normal distribution, as the sample size increases.

standard error of the mean

The ________ measures the degree of accuracy of the sample mean as an estimate of the population mean.

Standard Deviation

The standard error of the mean is also called ______

t-distribution

The ______ is a family of distributions that look almost identical to the normal distribution curve, only a bit shorter and stouter.

Students t-distribution

t-distribution is also called ____

Degree of freedom

This refers to the maximum number of logically independent values which vary in the data sample.

Percentile

This is a measure of position with data divided into 100 parts.
