Select the outlier in the data set. 3, 70, 76, 82, 84, 88, 92, 99

Identify data set: Identify the data set and look for the number that seems different from the others. Data set: 3, 70, 76, 82, 84, 88, 92, 99Calculate mean: Calculate the mean (average) of the data set. Mean = (3 + 70 + 76 + 82 + 84 + 88 + 92 + 99) / 8 Mean = 594 / 8 Mean = 74.25Calculate deviations: Calculate the deviations of each number from the mean and identify the largest deviation. Deviations: |3 - 74.25| = 71.25, |70 - 74.25| = 4.25, |76 - 74.25| = 1.75, |82 - 74.25| = 7.75, |84 - 74.25| = 9.75, |88 - 74.25| = 13.75, |92 - 74.25| = 17.75, |99 - 74.25| = 24.75 Largest deviation: 71.25 from the number 3

Q. Select the outlier in the data set.

\newline

3, 70, 76, 82, 84, 88, 92, 99

Identify data set: Identify the data set and look for the number that seems different from the others. $\newline$ Data set: $3, 70, 76, 82, 84, 88, 92, 99$
Calculate mean: Calculate the mean (average) of the data set. $\newline$ Mean = $(3 + 70 + 76 + 82 + 84 + 88 + 92 + 99) / 8$ $\newline$ Mean = $594 / 8$ $\newline$ Mean = $74.25$
Calculate deviations: Calculate the deviations of each number from the mean and identify the largest deviation. $\newline$ Deviations: $|3 - 74.25| = 71.25$ , $|70 - 74.25| = 4.25$ , $|76 - 74.25| = 1.75$ , $|82 - 74.25| = 7.75$ , $|84 - 74.25| = 9.75$ , $|88 - 74.25| = 13.75$ , $|92 - 74.25| = 17.75$ , $|99 - 74.25| = 24.75$ $\newline$ Largest deviation: $71.25$ from the number $3$
