Question

Question 1 (1 point) Which of the following statements are true? There may be more than one correct statement; check all that are true. The main point of inferential statistics is to use parameters to estimate statistics. Well-designed experiments are better than observational studies at showing evidence of a causal relationship between variables. A statistic is a numerical characteristic of a sample. There is no need to randomize in an experiment, but random selection is very important in observational studies.
