find the standard deviation of first 7 natural numbers
Answers
Answer:
Standard deviation of first 7 natural numbers is 2.16 .
Step-by-step explanation:
The first seven natural numbers are 1, 2, 3, 4, 5, 6, 7 ;
X X -
1 1 - 4 = -3 9
2 2 - 4 = -2 4
3 3 - 4 = -1 1
4 4 - 4 = 0 0
5 5 - 4 = 1 1
6 6 - 4 = 2 4
7 7 - 4 = 3 9
Firstly, Mean of first seven natural numbers =
Mean = = 4
Standard deviation = = = 2.16
Therefore, standard deviation of first 7 natural numbers is 2.16 .
