Answer:
b. To increase the accuracy of the research and prevent skewness in the idea.
Step-by-step explanation:
Random assignment ensures that any difference between groups recorded at the end of an experiment can be attributed to the experimental procedures. It refers to how you arrange the participants into required groups (different treatment and control groups). In the case of non-random assignment, the two major problems are generalisation of results and bias, which could lead to skewness in the idea of the experiment.
One of the importance of random assignment in this given experiment is to increase the accuracy of the research and prevent skewness in the idea.
