### The box plot above represents data which is:

• A.

Perfectly Symmetrical

• B.

Approximately Symmetrical

• C.

Positively Skewed

• D.

Negatively Skewed

• E.

With Outlier(s)

• F.

Approximately Symmetrical, but Bi-modal

C. Positively Skewed
Explanation
The box plot above represents data that is positively skewed. This means that the tail of the distribution extends towards the higher values, indicating that there are more data points on the lower end of the scale. The median is closer to the lower quartile, and the upper quartile is further away from the median. This suggests that there are a few extreme values in the data set that are driving the skewness.
