Given
- variance 0.49
To find
- standard deviation
Solution
we are provided with variance of the distribution as 0.49 and are expected to find the standard deviation.
From the standard equation of standard deviation we can and find the answer.
we know that standard deviation is the square root of variance of the distribution
ie, standard deviation = √(variance)
therefore,
standard deviation = √0.49
or, standard deviation = 0.7
Hence, the standard deviation of the distribution is 0.7
