In a hypothesis test standard error measures
WebSep 30, 2024 · The standard error measures the dispersion of the distribution. As the sample size gets larger, the dispersion gets smaller, and the mean of the distribution is closer to the population mean ( Central Limit Theory ). Thus, the sample size is negatively correlated with the standard error of a sample. WebIn a hypothesis test, standard error measures ____. a. the size of the treatment effect b. variability for the sample data c. the likelihood of a Type I or Type II error d.the amount of difference expected just by chance d. the amount of difference expected just by chance 10.
