Question

which of the following is false about experiments? the larger the sample size the more meaningful the results. the smaller the sample size the more meaningful the results. an experiment is not valid without the proper control. it is important to standardize aspects of an experiment which might affect the outcome, other than the independent variable. all answers are correct.

Explanation:

• Larger sample sizes reduce random error, making results more statistically meaningful, so the first statement is true.
• Smaller sample sizes are more prone to random variation and less likely to produce meaningful, generalizable results, so this statement is false.
• Proper controls are essential to isolate the effect of the independent variable, making an experiment valid, so the third statement is true.
• Standardizing all factors except the independent variable ensures that only the intended variable affects the outcome, which is a core experimental principle, so the fourth statement is true.
• Since one statement is false, "All answers are correct" is also false.

Answer:

B. The smaller the sample size the more meaningful the results.
