Problem: I need a response to this reply including a in text citation and including a question from the same reference: Ashley, The t-distribution is helpful in psychology because many studies use small samples and the population standard deviation is unknown. The t-test adjusts for this uncertainty, which helps researchers still analyze their data. However, results can be misleading if the sample size is very small, the data are not normally distributed, or the sample does not represent the larger population. In those cases, the results may not apply well to the general population. Need Assignment Help?
