Answer :
Final answer:
To find the sample standard deviation, calculate the mean of the data set, subtract the mean from each number and square the result, compute the mean of these squared differences (the variance), and then find the square root of the variance. The resulting value is the standard deviation, which should then be rounded according to the instructions.
Explanation:
To calculate the sample standard deviation for the provided data set, we first need to find the mean of the data. This involves adding all the numbers together and then dividing by the total count. Once we have the mean, the next step is to subtract the mean from each number in the data set and square the result, creating a list of squared differences. The mean of these squared differences is known as the variance.
The standard deviation is then calculated by finding the square root of the variance. Remember to round to one more decimal place than the largest number of decimal places given in the data.
A crucial point to note is to only round off your final answer for precision and maintain all decimal places in between calculations. It's also important to understand that the standard deviation measures the amount of variation or dispersion from the average within your data set.
