Find the median, lower quartile and upper quartile. Follow me on Pinterest. Your email is safe with us. In previous sessions, we worked problems involving the mean and median. Greater distances in the diagram should correspond to greater distances between numeric values. Notice that 12 is included in the lower half since it is below the median value.

When we relate two data sets based on the same scale, we may examine box-and-whisker plots to get an idea of how the two data sets compare. Measures of central tendency.

Determine the range and interquartile range for the amount collected. First, we write data in increasing order: Everything you need to prepare for an important exam! From our Example 2’s on the previous pages, we see that the five-number summary is:. For this session, we primarily use the median.
