You may have guessed that the second quartile is the same as the median, since the median is the value so that 50% of the data values are below it. If there are outliers and the data doesn't appear to be normally distributed, then the median is a better choice than the mean because it more accurately reflects the true midpoint of your data. Print out each page and cut on the dotted lines. All three of these sets of data have a mean of 5 and median of 5, yet the sets of scores are clearly quite different. Continuing our counting from earlier, The next 19 data values are $35, so Values 43 to (42+19)=61 are $35 thousand, The next 20 data values are $40, so Values 61 to (61+20)=81 are $40 thousand. The midrange is the average of the smallest and largest values in the data set. Counting up in the data as we did before, There are 6 data values of $15, so Values 1 to 6 are $15 thousand, The next 8 data values are $20, so Values 7 to (6+8)=14 are $20 thousand, The next 11 data values are $25, so Values 15 to (14+11)=25 are $25 thousand, The next 17 data values are $30, so Values 26 to (25+17)=42 are $30 thousand. However, suppose we add a fourth section, Section D, with scores 0, 5, 5, 5, 5, 5, 5, 5, 5, 10.
