Should Lin use the mean and MAD or the median and IQR to summarize her data? Explain your reasoning

Lin thinks that she could find the median, the minimum, and the maximum of the data set using both the dot plot and the histogram. Do you agree?

Should Lin use the mean and MAD or the median and IQR to summarize her data? Explain your reasoning

Disagree. The dot plot makes it possible to find the median, the minimum, and the maximum fairly easily since it shows each data value individually. The histogram makes it possible to estimate these values, but it is impossible to tell the exact values because the data points are grouped together.

Disagree.  You can not isolate individual data points on the dot plot or the histogram.  You would have to estimate the median, minimum, and maximum for both the dot plot and histogram.

Lin should use the mean and MAD because the data is perfectly symmetrical along the 2-3 hour range.

Lind should use the mean and MAD because they will be the exact same value and perfectly summarize this data set.
