Question

75,69,88,55,95,88,73,64,75,98,88,9590,95,88,44,59,67,88,99 find the median or mode of the data

Answer 1

it is a grouped data .there are 19 observations in this data. that is odd number of observations.
so formula for odd number of observations is (n+1)/2

first we need to write these observations in one order either ascending or descending.

now I am writing this in ascending.
44,55,59,64,67,69,73,75,75,88,88,88,88,88,95,95,98,9990.
let us apply the median formula (n+1)/2

=(19+1)/2

=20/2

=10

10 th number is 88 in written observation with ascending order.
...............................................

MODE:-

In the given observation 88 number is repeated more than two times so the mode is no mode
