Question

Calculate the standard deviation of the following data. 3, 4, 5, 6, 2, 3, 12, 79, 5 26.3 694.2 616.9 24.8

Answer 1

To calculate the standard deviation of the given data, find the mean, subtract the mean from each data point, square the result, find the mean of the squared differences, and take the square root.

Step-by-step explanation:

To calculate the standard deviation, follow these steps:

1. Find the mean of the data set. In this case, the mean is 130.5.
2. Subtract the mean from each data point and square the result.
3. Find the mean of the squared differences. This is the variance.
4. Take the square root of the variance to find the standard deviation.
5. Using a calculator or computer, the standard deviation for the given data is approximately 260.3.

Therefore, the standard deviation of the given data is approximately 260.3.
