The following is a true statement about random sampling and random assignment: An experiment requires random sampling and random assignment.

Random sampling is a method of selecting participants from a larger population in a way that each member of the population has an equal chance of being chosen as part of the sample. The participants should be chosen randomly so that the researcher gets a representative sample of the population that they want to study.

This process helps to minimize bias and increase the generalizability of the findings.Random assignment refers to the process of assigning participants to experimental and control groups randomly. In an experiment, participants are randomly assigned to one of the groups in order to avoid any pre-existing differences between the groups, and to ensure that any observed differences in outcomes are due to the intervention and not due to any pre-existing differences between the groups.

This helps to increase the internal validity of the study.An experiment requires random sampling and random assignment because both of these methods are used to increase the generalizability and internal validity of the study. A quasi-experiment is similar to an experiment, but it does not require random sampling.

However, it does require random assignment in order to ensure that any observed differences are due to the intervention and not due to any pre-existing differences between the groups.
