Randomization in an experiment Is important because it ensures that the treatments have an effect on the response. the individuals who will be in the study were chosen randomly. the groups of subjects are similar, on average, in all respects before applying the different treatments to the different groups. each individual has a fair chance of being included in the study. each treatment is thought of as a value of the explanatory variable.

The groups of subjects are similar, on average, in all respects before applying the different treatments to the different groups

Step-by-step explanation:

Randomization is a technique employed by researchers, which seeks to measure the effect of a treatment on a particular variable. The group is divided into the control and treatment groups. Treatment is administered to each group, and the effect is compared between them. The most important value of randomization is that it ensures that the groups who would be receiving treatments are similar on average to prevent bias caused by systematic differences. It also helps to ensure that each participant in the study has an equal chance of being selected for the study thus eliminating selection bias.

Randomization ensures that both participants and researchers do not have prior knowledge of the experiment which might influence their response to treatment.
