Are there any outliers in the given data​ set?

A.

​Yes, there are values above the upper fence.

B.

​No, all the values are between the lower and upper fences.

C.

​Yes, there are values below the lower fence.

D.

​Yes, there are values above the upper fence and below the lower fence.

To determine if there are outliers in a dataset, we need to calculate the lower and upper fences. These are defined as:

- **Lower fence**: \( Q_1 - 1.5 \times IQR \)
- **Upper fence**: \( Q_3 + 1.5 \times IQR \)

Where:
- \( Q_1 \) is the first quartile (25th percentile),
- \( Q_3 \) is the third quartile (75th

Are there any outliers in the given data set?

Learn how to identify outliers in a dataset by calculating the lower and upper fences using quartiles and the interquartile range (IQR). This method helps detect data points above the upper fence or below the lower fence, making it suitable for students in Grades 9-12.
