The most familiar statistical measure is the arithmetic mean, or average. A second important statistical measure is the standard deviation, which is the measure of how far the individual scores are from the mean. For example, the mean score on the Wechsler IQ test is 100 and the standard deviation is 15. This means that people within one deviation have an IQ that is 15 points higher or lower than the average. a) Write an absolute value equation for the maximum and minimum test scores within one standard deviation if the mean was 80 and the standard deviation was 12. b) What are the scores?
What is a) the absolute value of x-80 is equal to 12. b) 68 and 92
