Quizplus · Accepted Answer

Inferential statistics assume that variables are normally distributed in the population. This assumption is necessary for many statistical tests to be valid. While variables can be transformed into z-scores, this is not a requirement for inferential statistics. The personalities of participants are also not a factor in the use of inferential statistics. Additionally, while researchers can collect data from populations, they typically collect data from samples to make inferences about the larger population.
