Find the standard deviation of the following data. Round your answer to one decimal place.
x | 0 | 1 | 2 | 3 | 4 | 5 |
---|---|---|---|---|---|---|
P(X=x) | 0.2 | 0.1 | 0.1 | 0.2 | 0.2 | 0.2 |
Solution:
X | P(X) | X*P(X) | X^2*P(X) |
0 | 0.2 | 0 | 0 |
1 | 0.1 | 0.1 | 0.1 |
2 | 0.1 | 0.2 | 0.4 |
3 | 0.2 | 0.6 | 1.8 |
4 | 0.2 | 0.8 | 3.2 |
5 | 0.2 | 1.7 | 5.5 |
Sum = | 1 | 3.4 | 11 |
Mean :
= X * P(X)
= 3.4
Standard deviation:
= X2 * P(X) - ()2
= 11 - ( 3.4 )2
= -0.56
= 0.7
