Answer 1

Answer:

◆MEAN》

▪︎SUM OF ALL OBSERVATIONS / NO.OF OBSERVATIONS = MEAN

4 + 5 + 9 + 10 + 4 + 5 + 6 + 4 + 5 + 8 + 4 + 9 + 5 + 7 + 5 = 90÷15 = 6

★HENCE,

MEAN OF THE OBSERVATIONS = 6

◆MODE》

▪︎ Observation appeared the maximum time in the above data is the mode.

4,4,4,4,5,5,5,5,5,6,7,8,9,10

4,4,4,4,{5,5,5,5,5},6,7,8,9,10

5 appeared the maximum time in the above data

★HENCE,

MODE OF THE DATA IS 5.

◆MEDIAN》

▪︎ The center of the observations is the median.

4,4,4,4,5,5,5,5,5,6,7,8,9,10

= 4 , 5 , 6 , { 7 }, 8 , 9 , 10
