Male+Cicada+Wing+Length

=**Mean Absolute Deviation of Male Cicada Wing Length Data**= date developed: 9/3/12 date posted: 12/31/12 Return to Mean Absolute Deviation


 * TinkerPlots File - raw data**

In this data set, I started with a random sample of male cicadas, but the mean is 27 2/3 which causes rounding issues. My target mean is 28, so the sum needs to be increased to 336. I changed the third cicada's wing length from 26 to 30. [Why didn't this change affect the MAD value of approximately 2.167?]
 * Introduction**

The MAD for the male cicadas' wing length is approximately 2.2 mm. This is about double the MAD value for the females' MAD value of 1.125 mm.
