Select the outlier in the data set. 57, 67, 69, 73, 76, 79, 82, 90, 531

Identify Outlier: List the data set and observe the values to identify any number that seems significantly different from the others. Data set: 57, 67, 69, 73, 76, 79, 82, 90, 531 By observation, 531 seems much larger than all other values in the data set.Calculate Range and IQR: Calculate the range and the interquartile range (IQR) of the data set to determine the outlier formally. However, since the data set is small and one number is significantly larger than the rest, we can identify the outlier without detailed calculations. 531 is much larger than the next highest number, 90, indicating that it is an outlier.Confirm Outlier: Confirm that 531 is an outlier by comparing it to the rest of the data set. All other numbers are within a close range of each other (57 to 90), while 531 is significantly higher. 531 is the outlier.

Q. Select the outlier in the data set.

\newline

57, 67, 69, 73, 76, 79, 82, 90, 531

Identify Outlier: List the data set and observe the values to identify any number that seems significantly different from the others. $\newline$ Data set: $57, 67, 69, 73, 76, 79, 82, 90, 531$ $\newline$ By observation, $531$ seems much larger than all other values in the data set.
Calculate Range and IQR: Calculate the range and the interquartile range (IQR) of the data set to determine the outlier formally. However, since the data set is small and one number is significantly larger than the rest, we can identify the outlier without detailed calculations. $\newline$ $531$ is much larger than the next highest number, $90$ , indicating that it is an outlier.
Confirm Outlier: Confirm that $531$ is an outlier by comparing it to the rest of the data set. All other numbers are within a close range of each other ( $57$ to $90$ ), while $531$ is significantly higher. $\newline$ $531$ is the outlier.
