Answer:
mean=80.833
median=84.5
Step-by-step explanation:
scores:
95,45,37,82,90,100,91,78,67,84,85,85,82,91,93,92,75,84,100,59,92,77,68,88
we arrange the scores in ascending order
37,45,59,67,68,75,77,78,82,82,84,84,85,85,88,90,91,91,92,92,93,95,100,100
mean=sum of all observations/total number of observations
= 1940/24
=80.833
median is the central tendency of all observations
median lies between 84 and 85
median=(84+85)/2
= 84.5
