Which of the following pertaining to the design of an experiment is incorrect?

Select one:

a. The control variable should be tested first, followed by the testing of the experimental group thereby minimizing interference of the introduced variable between the two groups.

b. All extraneous variables should be controlled for such that the treatment and control groups only differ with respect to the variable in question.

c. All of these statements are correct.

d. The hypothesis should be a proposal that is readily testable, thereby allowing the validity of the hypothesis to be supported.

e. A flow chart should be created to outline the order in which the procedure of the experiment is performed, taking into account the experimental set-up and the hypothesis in question.

Solution

1. Hypothesis is making possible answers, which is to be tested later. So hypothesis is made before the experiment.

2. It can be tested in a procedure. It can not be readily testable. Control variable should be tested.

3. So from the above option \"d- The hypothesis should be a proposal that is readily testable, thereby allowing the validity of the hypothesis to be supported\"

4. Remaining all statements are correct.
