ANSWER
Arranging given marks in ascending order,
4,7,7,9,9,9,10,12,15
Number of observations (n)=9
⇒ Mean=
9
4+7+7+9+9+9+10+12+15
=
9
82
=9.11
⇒ Here, number 9 occurs maximum number of times i.e 3 times.
∴ Mode=9
Number of observation is odd number
∴ Median=(
2
n+1
)
th
obs=(
2
9+1
)
th
obs=5
th
obs
Here, 5
th
obs=9
∴ Median=9
