Question

according to the information provided in the video, which of the following is true: surveys and experiments are similar in that they both require random sampling. surveys require random assignment of those interviewed while experiments require random sampling. surveys require a random sample just as much as experiments need random assignment surveys and experiments are similar in that they both require random assignment.

Explanation:

Surveys aim to generalize to a larger population, so they rely on random sampling to select participants representatively. Experiments focus on establishing causal relationships, which requires random assignment of participants to groups to control for confounding variables. The other options mix up these key requirements: the first incorrectly states experiments need random sampling as a core requirement, the second reverses the requirements, and the fourth incorrectly claims both need random assignment.

Answer:

Surveys require a random sample just as much as experiments need random assignment
