The margin of error is obtained as the ratio of the standard deviation and the square root of the sample size. It is a measure of the amount of difference that is expected to exist between the actual population value and the value obtained from the sample.
- <em>Margin of Error = ±0.01</em>
<u>Margin of Error can be calculated using the relation</u> :
Margin of Error = 0.228 ÷ √500 = 0.010
Therefore. the margin of error can be interpreted to mean that the value of the mean obtained from the sample is expected to differ from the mean of the population weight by ±0.01

The next step Nolan should take is to find the average of the distances from the mean.
<h3>What is meant by mean absolute deviation?</h3>
A measure of variance in a data set is the mean absolute deviation. We may determine how "spread out" the values in a data collection are by looking at the mean absolute deviation.
The steps to find mean absolute deviation are:
- Calculate the mean of the data set
- Calculate the value of distance between the mean and each point in the data set.
- Find the average of the distances from the mean.
Hence, The next step Nolan should take is to find the average of the distances from the mean.
