should ignore this concept. The standard deviation is kind of the "mean of the mean‚" and often can help you find the story behind the data. To understand this concept‚ it can help to learn about what statisticians call normal distribution of data. A normal distribution of data means that most of the examples in a set of data are close to the "average‚" while relatively few examples tend to one extreme or the other. Let ’s say you are writing a story about nutrition. You need to look at
