Which of the following represents the median in a box plot?

The median in a box plot is represented by the middle value when the data is arranged in order. In statistical terms, the median divides the data set into two equal halves, meaning that 50% of the values are below the median and 50% are above it. In a box plot, the median is typically depicted by a line inside the box, which represents the interquartile range. This visual representation helps to easily identify the central tendency of the data while also providing insight into its variability.

The other options do not correctly describe the median. The highest value represents the maximum of the data set, the range is a measure of spread from the minimum to the maximum, and the mode refers to the most frequently occurring value, none of which convey the concept of the median accurately.
