Question

g In an experimental procedure using two groups, randomization ensures that ______. Multiple choice question. the experimental group and the control group will have a set of matching variables the participants are grouped together based on shared characteristics the individual characteristic composition of the two groups will be virtually identical in every way the extraneous variable is more likely to affect the control group than the experimental group

Answer 1

the experimental group and the control group will have a set of matching variables

individual characteristic composition of the two groups will be virtually identical in every way

Step-by-step explanation:

Randomization is done in an experiment to ensure even distribution of the two groups across the environment and to avoid bias. It ensures that the characteristics of the variables is shared among the two groups knowing that this variable can affect the outcome of the experiment.

It ensures that across the group experimental error is reduced to the minimum and accuracy is ensured.
