How do i compare two different mads? (mean absolute deviation)

Round to the nearest hundredth. describe what the  mean absolute deviation  represents. you can  compare  the  mean absolute deviations  for two data sets. a data set with a smaller  mean absolute deviation  has data values that are closer to the  mean  than a data set with a greater  mean absolute deviation. i also found a simple diagram that may .

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
