Tom developed the following scientific question Do boys score higher on IQ than girls He gives the same IQ tests to two 12 years old

Answer :

1. The experiment conducted by Tom is wrong because of the following:

  • Not a random example (sample)
  • Sample size is too small.

2. The independent variable is the IQ test while the dependent variables are the IQ scores of the four boys and girls. The constant is the number of testers. There is no control.

3. To improve the experiment, Tom needs to increase the sample sizes of boys and girls to at least 50 boys and 50 girls to make the generalization reasonable. He should obtain the IQ scores of girls as a control to compare the IQ scores of boys.
