What is meant by randomization? How does randomization affect the results of an experiment?
What will be an ideal response?
Randomization is the assignment of subjects by chance, rather than by choice, to a test group or control group. Assigning participants randomly will ensure that the result of the experiment is not biased. For example, suppose students with poor scores are assigned to one type of teaching method and students with good scores are assigned to another type of teaching method. It will be difficult to decide which teaching method is more effective as the students with the higher scores are likely to do better than the students with the poorer scores, irrespective of the teaching method used.
