To determine if half of the students spent at least a certain amount of time studying, we need to find the median (middle value) of the data. If the median is greater than or equal to that certain amount of time, then half of the students studied for at least that amount of time. If the median is less than that certain amount of time, then less than half of the students studied for at least that amount of time. Therefore, we would compute the median.
