### Deviations of the Mean

1. 1. Practice problem <br />8f + 6.1 ≥ -14f – 11.9<br />
2. 2. Practice problem<br />0.06p – 4 < .05p + 26<br />
3. 3. Deviations from the mean<br />
4. 4. Mean Absolute deviation<br />
5. 5. Measure of spread<br />Quantities that measure the degree of variation in data.<br />Class 1 Class 2<br />_______________ _______________<br />RANGE – the difference between the highest and lowest score.<br />
6. 6. Mean absolute deviation<br />A measure of spread that shows the difference between these distributions. <br />DEVIATION: The difference of each number from the mean<br />ABSOLUTE DEVIATION: Absolute value of each number found from the deviation<br />
7. 7. Property of the mean<br />“The sum of the deviations of a set of numbers from the mean of a set is 0.”<br />
8. 8. Applying the math<br />Table shows the normal mean temperatures in Fahrenheit for each month in San Francisco and Miami.<br />A: Calculate the range of mean temperatures for each city.<br />B: Use the mean absolute deviation to determine in which city the temperatures are more consistent. <br />
