click the arrows to choose an answer from each menu.
a mad of 65 means that the monthly enrollment counts were an average of 65 from the
choose... . an enrollment of 400 has a deviation value that is
choose... the mad. the data will have choose... variability when january’s
enrollment is included. this will result in a new mad that is choose... 65.

Explanation:

Step1: Understand MAD concept

Mean Absolute Deviation (MAD) measures the average distance of data points from the mean. So the first blank is "mean".

Step2: Analyze enrollment of 400

Current data range is 50 - 290. 400 is far from this range. Deviation of 400 from mean (assuming mean is around middle, say ~155 - 230 range) will be much larger than MAD (65). So "greater than" MAD.

Step3: Effect of adding 400

Adding an outlier (400) increases data spread, so variability becomes "greater".

Step4: New MAD after adding 400

Increased variability means new MAD is "greater than" 65.

Answer:

First "Choose...": mean
Second "Choose...": greater than
Third "Choose...": greater
Fourth "Choose...": greater than
