A. they are the same thing B. a sample distribution shows scores for a population and a population distribution shows scores for a sample C. a sample distribution shows scores for a sample and a population distribution shows scores for a population D. a sample distribution shows a distribution of sample statistics and a population distribution shows scores for a population - answer - C. a sample distribution shows scores for a sample and a population distribution shows scores for a population According to the central limit theorem, what happens to a sampling distribution as n gets larger? A. the distribution gets wider B. the distribution becomes negative C. the distribution becomes more normal D. the distribution requires a q-test in order to be analyzed - answer - C. the distribution becomes more normal What does standard deviation indicate in a set of data? A. how reliable the mean is B. that the mean accurately reflects the population C. how much the data differs from the mean on a average D. the data is significantly different than a control set - answer - C. how much the data differs from the mean on average What is the difference between a sample distribution and a sampling distribution? A. A sampling distribution is a distribution of different samples, a sample distribution is a sample of individual scores B. A sample distribution is normally distributed whereas the sampling distribution might not be C. A sample distribution has a smaller sample size D. There is no difference - answer - A. a sampling distribution is a distribution of different samples, a sample distribution is a sample of individual scores What's the difference between standard error and standard deviation? A. Standard deviation is an indication of how reliable the mean is B. A smaller standard deviation indicates that a mean is an accurate reflection of the population C. A larger standard deviation indicates that a mean is an accurate reflection of the population D. Standard deviation is an indicator of how far data differs from the mean on average - answer - D. standard deviation is an indicator of how far data differs from the mean on average What is the requirement for something to be considered a random sample?

Standard deviation is an indicator of how far data differ from the mean (on average), and standard error is an indicator of how reliable the mean is. B. Standard deviation is an indicator of how reliable the mean is, and standard error is an indicator of how far data differ from the mean (on average). C. They're a different phrase for the exact same thing D. None of the above - answer - A. standard deviation is an indicator of how far data differ from the mean (on average), and standard error is an indicator of how reliable the mean is Standard error... A. Is an indicator of how reliable
