Q. Select the outlier in the data set.
- List Data Set: List the data set in order to visualize the numbers and look for any number that appears to be significantly different from the others.Data set:
- Calculate Mean: Calculate the mean (average) of the data set.Mean = Mean = Mean =
- Calculate Standard Deviation: Calculate the standard deviation to understand the spread of the data. However, for a quick outlier check, we can skip this step and look for a number that is significantly higher or lower than the mean.
- Compare to Mean: Compare each number in the data set to the mean to see if any number is significantly higher or lower than the mean.- The number is significantly higher than the mean ().- All other numbers are relatively close to the mean when compared to .
- Identify Outlier: Identify the outlier based on the comparison.- The number stands out as the outlier because it is much larger than the rest of the numbers in the data set and the mean.
