Chapter 5 Flashcards
Sampling error
The error caused by observing only a sample rather than the whole population
Sampling variability
When the sample mean varies from sample to sample
If statistics vary from sample to sample they are ____
Random variables
The probability distributions for statistics are called ______
Sampling distributions
The distribution of all values of the statistic when all possible samples of the same size are taken from the same population is called
Sampling distribution of a statistic
Why would you want to use a large sample for a population?
A large sample is useful when there is high variability in the population
The standard error of the mean is also called
The standard deviation of the sample mean
When the sample size is large the distribution of the sample mean will be _____ even if the distribution of the population the sample was taken from was ______
The distribution of the sample mean will be normal
Population the sample was taken from was not normal
Sampling distribution is the is the ___
Probability distribution of the sample proportion
