Find the standard deviation for the given data. Round your answer to one more decimal place than the original data. 3, 5, 6, 6, 9, 1

Step-by-step explanation:

To find the standard deviation of a set of numbers, first find the mean (average) of the set of numbers:

3 + 5 + 6 + 6 + 9 + 1 / 6 = 30

30 / 6 = 5

Second, for each number in the set, subtract the mean and square the result:

(3−5)2+(5−5)2+(6−5)2+(6−5)2+(9−5)2+(1−5)2 = 12

  Then add all of the squares together and find the mean (average) of the squares, like this:  

12 / 6 = 2  

Finally, take the square root of the second mean:  

√2 = 1.46
