In In-Class Activity 14.C, your elderly aunt asked, \u201cWhat treatment works best to\u00a0 prevent osteoporosis?\u201d<\/p>\n

Now that we have shown that there was an overall difference, let\u2019s investigate the\u00a0 difference in the treatment options to answer your aunt\u2019s question. It is tempting to use the following boxplot to determine the answer, so we need to be careful. This method\u00a0 does not provide statistical EVIDENCE to support your conclusion.<\/p>\n

It is also tempting to only show the comparisons you want to show based on the\u00a0 boxplot. For example, only looking at comparisons including Calcium Pill Plus Exercise.<\/p>\n

This is called data snooping or data fishing. You cannot look at your results and then\u00a0 determine the comparisons that you want to make.<\/p>\n
