Question

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?

Answer 1

86,87,87,94,95,82,78,89,80,84
first arrange them or sort them
78,80,82,84,86,87,87,89,94,95
median is a middle value from left and from right
see 86 and 87 are middle point in total 10 numbers

so take avg of them 86+87/2
median is 86.5

Answer 2

Answer with Step-by-step explanation:

Median of the set of a data is the middle value of the data sets arranged in ascending order.

Here, we are given a data set:

86 87 87 94 95 82 78 89 80 84

Firstly we arrange the data set in ascending order:

78 80 82 84 86 87 87 89 94 95

The middle value of the above data lies between fifth and sixth value

i.e. between 86 and 87

Median=
`(86+87)/(2)`

= 86.5

Hence, the median score for these students are:

86.5
