The scores of several classmates on a language arts test are shown below:


86 points 87 points 87 points 94 points 95 points 82 points 78 points 89 points 80 points 84 points

What is the median score for these students? (4 points)


a

87.5 points


b

87 points


c

86.5 points


d

86 points

Answer 1

To find the median score, we need to arrange the scores in order from lowest to highest:

78, 80, 82, 84, 86, 87, 87, 89, 94, 95

There are 10 scores in total, so the median is the middle score. In this case, the middle two scores are 86 and 87. To find the median, we take the average of these two scores:

(86 + 87) / 2 = 86.5

Therefore, the median score for these students is 86.5 points, which is option (c).
