Example: To find the Standard deviation of the data set: 3,2,4,1,4,4. Step 1: Calculate the mean and deviation. uniform, then the standard deviation will be small. indicating that there is a wide variance in the responses, then the standard deviation will be large. meaning. deviation of 1.265 with a mean of 12.
