QUESTION 6
In a distribution with an even number of scores, the median is determined byfinding the most frequent score in the top half of the distribution and averaging it with the most frequent score in the bottom half of the distribution.finding the arithmetic average of the entire distribution and dividing it in half.averaging the middle pair of scores.finding the most frequent score.
