Final answer:
The statement regarding whiskers extending to the largest/smallest values outside the fences is false. Whiskers on a box-and-whisker plot represent values within the fences, not including outliers which may be marked separately.
Step-by-step explanation:
The statement "Whiskers go to the largest/smallest value outside the fences" is false. In a box-and-whisker plot, the two whiskers extend from the first quartile to the smallest value within the lower fence and from the third quartile to the largest value within the upper fence. The median is typically indicated by a dashed line within the box.
It is critical to recognize that whiskers do not always extend to the absolute minimum or maximum values, especially when those values are considered outliers. Outliers can be marked with dots or other symbols when they lie outside the fences, highlighting that they are not included in the range covered by the whiskers.
