Random is a process that ensures that every participant has an equal chance of being in any one of the experimental conditions and is common in scientific research, whereas random is when every member of the population has an equal chance of being a participant and is much less common in experimental studies.

Assignment

Sampling

Explanation:

In research, the term random assignment refers to the use of procedures that allow participants to have an equal chance of being assigned to any of the groups that will be part of the experiment. In other words, they are randomly assigned to the control group or the experimental group.

On the other hand, the term random sampling is a sampling technique in which each member has the same change of being chosen (in other words, they all have the same probability to be part of the study).

Therefore, we can conclude that Random assignment is a process that ensures that every participant has an equal chance of being in any one of the experimental conditions and is common in scientific research, whereas random sampling is when every member of the population has an equal chance of being a participant and is much less common in experimental studies.
