Answer: sample size
Explanation: sample size simply means the number of observations or items chosen as a representation of a population. Sample size is an important terminology used in statistical analysis as most statistical or experimental research cannot be performed using all the available observations in the entire population either due to cost or total impossibility. The larger the sample size, the better the generalization made about the entire population.
Therefore, a sample size consisting of 10,000 participants or observations will generalize more and hence, attract greater value and interest than the same analysis with a sample size of 24 participants.
Answer:
insufficient strength of the manipulation
Explanation:
The non-significant results may have occurred because of insufficient strength of the manipulation. Since the variable being tested in this scenario had a very slight difference it caused insignificant results. The variable in the study (light bulb) needs to be drastically different in order for it to have an effect on the subjects and provide results that differ. The 100-watt and 125-light bulb provide almost the same luminosity levels.
The answer is D because you want to have a control group! Hope it helps!
