Since 100 is an even number, we need to find the mean of the middle two data values - the 50th and 51st data values. So we find the mean of the two middle numbers, 6 and 7, and get (6+7)/2 = 6.5. If we add in the new neighbor with a $5 million household income, then there will be 101 data values, and the 51st value will be the median. The range is the difference between the maximum value and the minimum value of the data.

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. In some data sets, the data values are concentrated closely near the mean; in other data sets, the data values are more widely spread out from the mean. The mean household income of our sample is 33.9 thousand dollars ($33,900).
