Analysis of variance

The Standard Deviation is a measure of how spread out numbers are. Its symbol is???(the greek letter sigma) The formula is easy: it is the?square root?of the?Variance Variance = The average of the?squared?differences from the Mean. To calculate the variance follow these steps: Work out the Mean (the simple average of the numbers) Then for each number: subtract the Mean and square the result (the squared difference). Then work out the average of those squared differences. (Why Square?)

Statistics Ch. 6 Test REVIEW Name: KEY Date: Part 1: Multiple Choice (2 points each) Here are the means and standard deviations of the weights of two groups of cats. Which statement is true? Al the cats in group B weigh less than all the cats in group A. The weights of each group follow a Normal model. A 3.3 pound cat in group B is closer to average than an 8.2 pound cat in group A. Compared to group B, the weights in group A are closer to the mean. In a Normal model, what percent of data is between -1 and +2 standard deviations of the mean? 68 81.5 99.7 It depends upon the standard deviation Normal model A has a smaller standard deviation than Normal model B. How do the graphs of these models compare when drawn on the same scale?
