Answer 1

Answer:

Annyeong hasayo!

here's your answer,

Median: (Ascending order)

4,9,11,15,18,18

Observe that there are 6 terms where 11 appears as the 3rd position and 15 appears as the 4th position.

In such cases where there is no proper middle value, we consider the mean of the value that occurs at the third and fourth positions.

n/2th and ( n/2+1)

11+15/2=26/2=13

so the median of the data.

mode: mode is the most repeated value that occurs in the set of observations.

the mode is,18 .
