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?)

Percentile

Calculate?percentiles can tell us how numbers are distributed. Assume eight numbers: [0, 2, 4, 6, 8, 10, 12, 14] Notice that these 8 numbers are arranged from lowest to highest: That's how you need to arrange your numbers to calculate percentiles. If the numbers are not arranged lowest to highest, make sure you order them this way. This is important because a percentile tells you how well you did compared to others and that comparison needs to be organized. Let N equal the number of data points. Here N=8. The formula is P=(k/100)(n). K is the percentile you want to find. Here that's 75 P=(75/100)(8)=0.75(8)=6 P is the position in the distribution that corresponds to the 75th percentile. Here, it's the data point in the 6th position. The data set is [0, 2, 4, 6, 8,?10, 12, 14]

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?
