Chp 6 B

What are the quartiles of a​ distribution? How do we find​ them? What are the quartiles of a​ distribution?

The quartiles are values that divide the data distribution into quarters. How do we find​ them? The lower quartile is the median of the data values in the lower half of a data set. The middle quartile is the overall median. The upper quartile is the median of the data values in the upper half of data set.

The highest exam score was in the upper quartile of the distribution.

The statement makes sense because the highest score will be in the highest quartile.

Both exams had the same​ range, so they must have had the same median.

This does not make sense because the range is the difference between the highest and lowest data values. It has nothing to do with the median.
