Answer:

Step-by-step explanation:

mean= sum of observations/no. of observations

mean=(11+20+10+19+18+16+18+14+18)/9

mean=16

median of odd no. is n+1/2 th term after arranging it in ascending order,

10,11,14,16,18,19,20 where n=7

hence, 4th term that is 16 is the median

mode is the most repeated number that is 18.
