3 1 point Which of the following statements is TRUE about sample size? Sample size is only important in observation research, not experimental research. A large sample size decreases the likelihood that the results of your experiment will be influenced by random Sample size is not that important. It is more important to test multiple variables to have a strong experiment. A small sample size decreases the likelihood that the results of your experiment will be influenced by random

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.

Select all of the following statements which are true. In a randomized experiment, researchers can make cause-and-effect conclusions. A convenience sample using a sample size of 1000 would be preferred to a random sample with a sample size of only 200. The response variable will always be observed, never assigned, regardless of study design. Online polls typically result in non-response bias. A confounding variable must be related to the response variable, but not the explanatory variable. Non-random samples are usually poor representations of the population.
