In the context of this exercise, how does changing the mean and standard deviation affect descriptive and inferential statistics?
Changing the mean and standard deviation values will have a direct effect on descriptive statistics, since it deals with describing the dataset itself, without making any other inferences or conclusions about it. If we change the mean or standard deviation, descriptive statistics will just describe the updated dataset, which might have drastically different results than before.
However, changing the mean and standard deviation will usually not have as big an impact on inferential statistics as it will on descriptive statistics. This is because inferential statistics is based on inferences and conclusions about the larger population, so it is possible that the results and conclusions remain the same, or similar, even after we change the mean and standard deviation values.
