Question

Quizplus · Accepted Answer

Chance can affect the data in an experiment by producing differences between the means of the conditions. This means that the data from each group may vary due to chance, leading to differences in the overall mean between groups. This is why statistical tests are necessary to determine if the differences observed are statistically significant or simply due to chance. A and C are incorrect because the choice of statistics and variability levels can also be affected by chance. D is incorrect because chance does not reduce variability.
