Question

The heights in inches for five student are: 60, 67, 64, 54, 58 How would the median change if a student 68 inches tall is added to the group?

Answer 1

ok we first arrange them in ascending order

Answer 2

54,58,60,64,67 since there are 5 numbers, median is middle value

Answer 3

the median without 68 would be 60... so add a number and what would your median be?

Answer 4

middle value is 60

Answer 5

now we add 68

Answer 6

68 would be the 6th number in the list as it is the largest of all

Answer 7

now there are 6 numbers which is even...so to find the median we have to take the average of the two middle values

Answer 8

for the median with all those number their is two middle numbers, 60 and 64 so what is the median?

Answer 9

the two middle values here are 60 and 64....their average is (60 +64)/2

Answer 10

that is 124 /2 that is 62

Answer 11

so when u add 68 to the list the median changes from 60 to 62

Answer 12

do u understand? @sandyjayaram is correct

Answer 13

60, 67, 64, 54, 58
add
68
median before the new value is 60 yes
median after the new value depends on the definition of median
but the answers above confuse mean and median, I believe.

Answer 14

Oh you are right. sorry

Answer 15

for an even number of values, you form the average of the two central values in the list.

Answer 16

should've read the whole thread. sorry guys

Answer 17

54,58,60,64,67: the median of this is 60 cuz its the middle number
54,58,60,64,67,68:the median of this one is the two middle numbers added together and divided by 2= your answer is 62
