Question

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

Answer 1

To calculate the standard deviation, find the mean, subtract it from each value, square the result, find the average of the squared differences, and take the square root.

Step-by-step explanation:

The standard deviation of the given data can be calculated using the following steps:

1. Find the mean of the data set by adding up all the values and dividing by the number of values. In this case, the mean is 30.4.
2. Subtract the mean from each individual value and square the result. This gives us the squared differences from the mean.
3. Find the average of the squared differences by adding them up and dividing by the number of values.
4. Take the square root of the average of the squared differences to find the standard deviation. In this case, the standard deviation is approximately 22.5.
