Consider the following data:
\[
14,-12,-10,14,-10,14,-10
\]

Step 2 of 3: Calculate the value of the sample standard deviation. Round your answer to one decimal place.

Step 1 ：Given the data set \[14,-12,-10,14,-10,14,-10\]

Step 2 ：First, calculate the mean of the data set. The mean is the sum of all the numbers divided by the count of numbers. In this case, the mean is 0.0

Step 3 ：Next, for each number in the data set, subtract the mean and square the result. This gives us the squared differences

Step 4 ：Then, find the average of these squared differences. This is called the variance. In this case, the variance is 172.0

Step 5 ：Finally, to find the standard deviation, take the square root of the variance. This gives us the standard deviation of 13.1

Step 6 ：So, the sample standard deviation of the given data set is \(\boxed{13.1}\)
