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 rely on random sampling to select a representative group from a population to generalize findings. Experiments use random assignment to place participants into control/treatment groups to establish causal relationships.

• First option: False, experiments don't require random sampling, they need random assignment.
• Second option: False, surveys use random sampling, experiments use random assignment (reverse of this option).
• Third option: True, surveys depend on random sampling for representativeness, experiments depend on random assignment for causal inference.
• Fourth option: False, surveys don't require random assignment.

Answer:

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