Question

A well-designed experiment should have which of the following characteristics?

Answer 1

Answer:

The answer is E: I, II, and III

Step-by-step explanation:

The three major features of a well designed experiment are:

1. Replication: If an experiment cannot be replicated, then it is not a well-designed experiment. Replication is one of the major characteristics of a well designed experiment

2. Control: A well designed experiment must have a control. Control, in an experiment, can be referred to as the steps taken to curb the impact of extraneous variables

3. Randomization: Subjects are expected to be randomly assigned to different groups.
