Respuesta :
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 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= [tex]\dfrac{86+87}{2}[/tex]
= 86.5
Hence, the median score for these students are:
86.5
