The Pit and the Pendulum: Standard Deviation by Michael Rincon Bonillas https://padlet.com/201501555/xavs4y7nql4n What I have learned so far that I am proud of en-us 2017-02-27 19:49:13 UTC 2026-03-19 01:51:26 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Growing.png Standard deviation 201501555 https://padlet.com/201501555/xavs4y7nql4n/wish/156548456 Standard deviation is to measure the spread apart data is.
Calculating standard deviation: 
  1.  Find the mean of data set.
  2. Find the difference between each data item and the mean.
  3. Square each difference.
  4. Find the mean of these squared differences.
  5. Take the square root of this average. 
 Standard Deviation Equation:

Statements that are true when a set of data is normally distributed:
  •  Approximately 68% of all results are within one standard deviation of the mean
  • Approximately 95% of all results are within two standard deviations of the mean 
  • Last 5% of data are results of outliers in data set or "rare" data items/amounts.
