Full solution
Q. Select the outlier in the data set.
- List Data Set: List the data set and observe the values to identify any number that appears to be significantly different from the rest of the numbers.Data set: Observation: The number seems to be much lower than all other numbers in the set.
- Calculate Mean: Calculate the mean (average) of the data set.Mean = Mean = Mean =
- Calculate Standard Deviation: Calculate the standard deviation of the data set. This involves several sub-steps, but for the purpose of identifying an outlier, a rough estimate or comparison of how far each number is from the mean may suffice.
- Compare to Mean: Compare each number in the set to the mean to see which one is farthest away.- is units away from the mean.- is units away from the mean.- is units away from the mean.- is units away from the mean.- is units away from the mean.- is units away from the mean.- is units away from the mean.- is units away from the mean.Clearly, is significantly farther from the mean than all other numbers.
- Identify Outlier: Conclude which number is the outlier based on the comparison.The number is the outlier because it is significantly farther from the mean than any other number in the set.
