#### Transcript of Looking at the Math: MAD and IQR

Assignment
Take pictures of your dot plots and box plots and upload them into the assignment. Upload your conclusions you were able to draw after calculating the MADs and the IQRs. Be sure you support your conclusions with the math.

Mean Absolute Deviation and Interquartile Range
Graphing the Data
Once everyone has posted their blubber data, you need to build two dot plots of the data- one for everyone's blubber hand data and one for everyone's non-blubber hand data. What observations can you make about the data?

Then please create two box plots of the data. What observations can you make about the data?

Calculate
Calculate the Mean Absolute Deviation (MAD) for each of your data sets- one MAD for the blubber hands and one MAD for the non-blubber hands.

Calculate the Interquartile Range (IQR) for or each of your data sets- one IQR for the blubber hands and one IQR for the non-blubber hands.
Mean Code: LZ2482
Median Code: LZ2758
Range Code: LZ2772
Shape: LZ3109
Clusters, Peaks, and Gaps: LZ3264
Measures of Center vs. Measures of Variance Code: LZ3491
