WebThe standard deviation is a measure of how close the numbers are to the mean. If the standard deviation is big, then the data is more "dispersed" or "diverse". As an example let's take two small sets of numbers: 4.9, 5.1, 6.2, 7.8 and 1.6, 3.9, 7.7, 10.8 The average (mean) of both these sets is 6. WebRound 1: All scores are the same. All judges have a 100% consistency rate, and the round average is 100%. Round 2: 2 10-9's, 1 10-8 so, red is 100% consistency, but blue side is not. 9 is the correct answer (100%), 8 is 1 point off and is the deviation that needs to be measured (<100%). Judges 1&2 have 100% average consistency rate, Judge 3 has ...
