Answer:
Step-by-step explanation:
- MAD is simply the average distance that all of the numbers in your data set are from the mean.
- Your first step is to put your data in order, then determine the mean.
- Let’s look at this data set:
0.3, 0.5, 0.9, 1.1
- The mean of this data set is 0.7
- Starting with the lower extreme, and checking every number in your data set, determine how far each number is from the mean.
- First, put the numbers in numerical order, from least to greatest.
- Determine the distance each number is from 0.7.
- 0.3=0.4
- 0.5=0.2
- 0.9=0.2
- 1.1=0.4
- Add up all of the distances.
- Total distance from the mean (12) ÷ 4 numbers in our data set = a mean absolute deviation of 3.
