Answer:
Step-by step explanation:
median = arrange small to big(for even count of numbers)
=3,7,9,12,12,14,15,16,16,16,17,19
= average of 2 numbers in middle = 14+15 = 29/2=14.5= median
note= 1. if the number counts are even then select the half of the number and The next number eg: here the counts are 12 so 6th and 7th number should be selected AND BUST BE ADDED AND DIVIDED BY 2. 2. if the number counts are odd then divide it with 2 (half) and then select the next number example: if the number counts are 5 then divide by 2=2.5 so then choose the 3rd number(2.5 next 3) eg: 1,2,4,6,7 median=4or use this way = 5+1/2=6/2=3rd number
mean= add all numbers= 156 then divide by 12(no. of counts)= 13
mode= largest value in list= 16
hope its clear thank you
