Worked+Problems+-+Standard+Deviation

Daniela Arce 10 teenagers took a [|survey] to see how many books they had at home. The results were 25, 13, 40, 10, 29, 50, 23, 37, 50, and 49. Step 1:To find the sample standard deviation, we first find the average of all the data by adding all the numbers and dividing the sum by the number of subjects. Step 2:We then subtract the average from each number. Step 3:Then, we square the answers. Step 4:After finding the square, we add all the numbers together and divide by the number of subjects minus 1. Step 5:Finally, we find the square root of that number and the result is the sample standard deviation.
