Select the outlier in the data set. 9, 36, 38, 39, 40, 42, 43, 45, 52

Identify Data Set: Step 1: Identify the data set and look for numbers that seem unusually high or low compared to the others. Data set: 9, 36, 38, 39, 40, 42, 43, 45, 52Calculate Range and Median: Step 2: Calculate the range and median to better understand the spread of the data. Range = Maximum value - Minimum value Range = 52 - 9 = 43 Median (middle value when data is ordered) = 40Compare to Median and Range: Step 3: Compare each number to the median and the range to see which number stands out. - 9 is significantly lower than the median (40) and is far from the closest number (36). - All other numbers are relatively close to each other and the median.Conclude Outlier: Step 4: Conclude which number is the outlier based on the comparison. - 9 is the outlier as it is significantly different and distant from the rest of the numbers in the set.

Q. Select the outlier in the data set.

\newline

9, 36, 38, 39, 40, 42, 43, 45, 52

Identify Data Set: Step $1$ : Identify the data set and look for numbers that seem unusually high or low compared to the others. $\newline$ Data set: $9, 36, 38, 39, 40, 42, 43, 45, 52$
Calculate Range and Median: Step $2$ : Calculate the range and median to better understand the spread of the data. $\newline$ Range = Maximum value - Minimum value $\newline$ Range = $52 - 9 = 43$ $\newline$ Median (middle value when data is ordered) = $40$
Compare to Median and Range: Step $3$ : Compare each number to the median and the range to see which number stands out. $\newline$ - $9$ is significantly lower than the median ( $40$ ) and is far from the closest number ( $36$ ). $\newline$ - All other numbers are relatively close to each other and the median.
Conclude Outlier: Step $4$ : Conclude which number is the outlier based on the comparison. $\newline$ - $9$ is the outlier as it is significantly different and distant from the rest of the numbers in the set.
