Now showing the standard deviation

From now on the videos show the standard deviation instead of the deviation range. I think the standard deviation is more comparable. From Wikipedia: "In statistics and probability theory, the standard deviation (SD) (represented by the Greek letter sigma, σ) measures the amount of variation or dispersion from the average. A low standard deviation indicates that the data points tend to be very close to the mean (also called expected value); a high standard deviation indicates that the data points are spread out over a large range of values."

Today I will upgrade all videos.
