Question

7,9,12,13,7,12,15,7,12,7,25,18,7 find the mean ,median mode​

Answer 1

Answer:

• mode is 7 because it repeat more times and median is 12 because by arranging numbers in ascending or decending order the middle number is 12 and the mean is 11.6 because by doing the sum of all numbers it's value is 151 and by doing it by 13 the value is 11.6

Answer 2

ANSWER  

Mean = sum of observation / total number of observation

sum = 7+9+12+13+7+12+15+7+12+7+25+18+7=151

mean=151/13=11.61

Median=(n + 1)/2)th term

arrange in assending order=7,7,7,7,7,9,12,12,12,13,15,18,25

n = number of terms=13

median = 13+1/2=7th term=12
