Select the outlier in the data set. 9, 56, 62, 64, 69, 72, 74, 84

Identify Data Set: Step 1: Identify the data set and the need to find the outlier. Data set: 9, 56, 62, 64, 69, 72, 74, 84. We need to find the number which is significantly different from the others. Calculate Range and Median: Step 2: Calculate the range and median to observe any significant differences. Range = Maximum value - Minimum value Range = 84 - 9 = 75 Median (middle value of sorted data) = (69 + 72) / 2 = 70.5 Check if any number is far from the median and the rest of the data. Compare Numbers to Median: Step 3: Compare each number to the median and the rest of the data. Most numbers are clustered around the median (70.5), except for 9, which is much lower than the next closest number (56). This suggests 9 is an outlier.

Q. Select the outlier in the data set.

\newline

9, 56, 62, 64, 69, 72, 74, 84

Identify Data Set: Step $1$ : Identify the data set and the need to find the outlier. $\newline$ Data set: $9, 56, 62, 64, 69, 72, 74, 84$ . $\newline$ We need to find the number which is significantly different from the others.
Calculate Range and Median: Step $2$ : Calculate the range and median to observe any significant differences. $\newline$ Range = Maximum value - Minimum value $\newline$ Range = $84 - 9 = 75$ $\newline$ Median (middle value of sorted data) = $(69 + 72) / 2 = 70.5$ $\newline$ Check if any number is far from the median and the rest of the data.
Compare Numbers to Median: Step $3$ : Compare each number to the median and the rest of the data. $\newline$ Most numbers are clustered around the median ( $70.5$ ), except for $9$ , which is much lower than the next closest number ( $56$ ). $\newline$ This suggests $9$ is an outlier.
