Select the outlier in the data set. 5, 72, 78, 85, 87, 94, 98, 99

Identify Data Set: Step 1: Identify the data set and look for numbers that seem unusually low or high compared to the others. Data set: 5, 72, 78, 85, 87, 94, 98, 99Calculate Range and Median: Step 2: Calculate the range and median to understand the spread and central tendency of the data. Range = 99 - 5 = 94 Median (middle value of sorted data) = (85 + 87) / 2 = 86Compare to Median and Range: Step 3: Compare each number to the median and range to see which number stands out. - 5 is significantly lower than the median (86) and far from the closest number (72). - All other numbers are closely packed between 72 and 99.

Q. Select the outlier in the data set.

\newline

5, 72, 78, 85, 87, 94, 98, 99

Identify Data Set: Step $1$ : Identify the data set and look for numbers that seem unusually low or high compared to the others. $\newline$ Data set: $5, 72, 78, 85, 87, 94, 98, 99$
Calculate Range and Median: Step $2$ : Calculate the range and median to understand the spread and central tendency of the data. $\newline$ Range = $99 - 5 = 94$ $\newline$ Median (middle value of sorted data) = $(85 + 87) / 2 = 86$
Compare to Median and Range: Step $3$ : Compare each number to the median and range to see which number stands out. $\newline$ - $5$ is significantly lower than the median ( $86$ ) and far from the closest number ( $72$ ). $\newline$ - All other numbers are closely packed between $72$ and $99$ .
