In a box-and-whisker plot (boxplot), the value that splits the dataset in half, with 50% of the observations above and 50% below, is the median. This is represented by the line inside the box.

From the image, the line inside the box appears to be around 60, indicating that the median value of the dataset is approximately 60.
