Find the mean of the following data:
1,3,5,7,9,11,13,15
Given : 1,3,5,7,9,11,13,15
We know that,
Mean=SumofallobservationsTotalnumberofobservations
=1+3+5+7+9+11+13+158
=648
=8
Hence, mean of the given observation is 8.
Without adding find the sum
(i) 1 + 3 + 5 + 7 + 9
(ii) 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19
(iii) 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23
The mean of the following data is 8:
