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...
Lastly, he adds these values together, and arrives at 0.26%, which is divided by 2 to arrive at the total variance of 0.13%. Then, he takes the square root of the total variance, or .0013,. which equals a deviation of 3.6%. Although this formula can seem intimidating, it is actually...
Mean absolute deviation is the average distance between the mean of a set of numbers. This is used to analyze statistics in many fields. Not only do you find the mean (average), but the distance between each number to the mean. Read Mean Absolute Deviation | Definition, Formula & Examples...
Added weight to outliers: Outliers are the numbers far from the mean. Squaring these numbers gives them more weight, which canskewthe data. Not often used alone: Variance is often used as a stepping stone to finding thestandard deviationof a dataset, rather than a measurement on its own. ...
