### How do you find the average deviation from mean?

To Find Average Deviation
1. Find the average value of your measurements.
2. Find the difference between your first value and the average
value. This is called the deviation.
3. Take the absolute value of this deviation.
4. Repeat steps 2 and 3 for your other values.
5. Find the average of the deviations. This is the average
deviation
The average deviation is an estimate of how far off the actual
values are from the average value, assuming that your measuring
device is accurate. You can use this as the estimated error.
Sometimes it is given as a number (numerical form) or as a
percentage.
To Find Percent Error
1. Divide the average deviation by the average value.
2. Multiply this value by 100.
3. Add the % symbol.
