This practice can mask meaningful differences between groups. The standard deviation, a measure that tells us how much our values are spread out from those averages and from each other. Standard deviations provide context to help us understand the means and are also informative by themselves.

Here in Part 1, we explain what the standard deviation SD is and why you should care. In Part 2, we apply your new knowledge step-by-step to some real salary data. By the end of this tutorial, you will be able to: Explain what the standard deviation is Understand why it is important Calculate the standard deviation in R Apply this knowledge to human capital and other business data Put your skills to work AT WORK As always, I strongly recommend following along at home using the code snippets below.

Suppose we have two groups of people. In the first group, we have 3 people who have taken 11, 13, and 15 unscheduled days off of work, giving us an average of 13 days. In our second group, we have 3 people who have An introduction to human capital 0, 13, and 26 unscheduled days off of work, again giving us an average of 13 days.

As I have noted in previous posts here and herethe mean is a useful measure because it summarizes all of the values we have into a single value.

We can then use that single values to compare groups. Here then, we see that both groups have a mean of 13 days. But your intuition is telling you that these groups are different and your intution is right: The problem is that averages tell us nothing about the spread or closeness of the values within those groups.

For that we need to the standard deviation. In essence, the standard deviation tells us how close our scores are to the group average. If the standard deviation is low, the scores are generally close to the mean and therefore close to one another. If the standard deviation is high, the individual scores are quite different from the mean and from one another.

The scores from Group 1 11, 13, and 15 are less spread out than the scores from Group 2 0, 13, Accordingly, the standard deviation for Group 1 will be less than that for Group 2. The Calculation Steps and What They Mean Here we show you the individual steps for calculating the standard deviation.

Normally, you would not be doing this by hand, but stepping through the logic by hand will help you understand what the standard deviation really means. Calculate the mean of the scores for your group.

Think of the mean as the reference point. Subtract each of the individual scores from the mean. This is tells us how far each individual value is from that mean reference point.

Square those difference scores and then add them all up. We are trying to get a total measure of all of the differences.

If just added them up without squaring them first though, the positive and negative values would just cancel out.

Divide that by one less than the number of scores you have. This is like getting an average of those difference scores. Take the square root of that value we obtained in Step 4. In this step we are essentially undoing that squaring business in Step 3 so we have a number that we can interpret.

This makes sense because the spread of the scores in Group 2 was much greater than the spread from Group 1. The standard deviation captures this difference. Calculating the Standard Deviation in R In R, we just use the sd function to calculate standard deviation.Contents | 1.
