Refer to the appliedpsychology in criminal justice (sept. 2009) study of thepersonality characteristics of convicted drug dealers,exercise 7.17 (p. 352). a random sample of 100 drugdealers had a mean wanting recognition (wr) score of39 points, with a standard deviation of 6 points. recallthat the wr score is a quantitative measure of a person’s level of need for approval and sensitivity to socialsituations. (higher scores indicate a greater need for approval.) a criminal psychologist claims that the range ofwr for the population of convicted drug dealers is 42 points. do you believe the psychologist’s claim? (hint: assume the population of wr scores is normally distributed.)

Standard deviation

Step-by-step explanation:

Average deviation can be calculated using the following steps;

Finding the mean of the five replicate data pointsFind absolute deviations of each data point by subtracting the mean value in the first step from each replicated data pointAdd the absolute deviation valuesDivide sum by 5 to get average deviation

Average deviation value is sometimes used as the value of standard deviation because it simpler to find.The standard deviation formula still requires more steps to be complete.
