Select the outlier in the data set. 20, 29, 31, 38, 39, 42, 64, 612

Identify Data Set: Step 1: Identify the data set and look for any number that seems significantly different from the others. Data set: 20, 29, 31, 38, 39, 42, 64, 612 Observation: 612 is much larger than the other numbers.Calculate Range and Median: Step 2: Calculate the range and median to confirm the outlier. Range = Maximum value - Minimum value Range = 612 - 20 = 592 Median (middle value of sorted data) = (39 + 42) / 2 = 40.5Compare Outlier with Median: Step 3: Compare the outlier with the median to see how far it deviates. Difference between 612 and median = 612 - 40.5 = 571.5 This difference is significantly larger than any other difference in the data set.

Q. Select the outlier in the data set.

\newline

20, 29, 31, 38, 39, 42, 64, 612

Identify Data Set: Step $1$ : Identify the data set and look for any number that seems significantly different from the others. $\newline$ Data set: $20, 29, 31, 38, 39, 42, 64, 612$ $\newline$ Observation: $612$ is much larger than the other numbers.
Calculate Range and Median: Step $2$ : Calculate the range and median to confirm the outlier. $\newline$ Range = Maximum value - Minimum value $\newline$ Range = $612 - 20 = 592$ $\newline$ Median (middle value of sorted data) = $(39 + 42) / 2 = 40.5$
Compare Outlier with Median: Step $3$ : Compare the outlier with the median to see how far it deviates. $\newline$ Difference between $612$ and median = $612 - 40.5 = 571.5$ $\newline$ This difference is significantly larger than any other difference in the data set.
