The question is incomplete. Here is the complete question.
The Minnesota Multiphasic Personality Inventory (MMPI) is one of the most frequently used personality tests in psychology. the current standardized version, the MMPI-2, is used by trained professionals to assist in identifying personality structure and psychopathology. A forensic psychologist is interested in whether she can identify potential serial killers by their MMPI profiles. She is particularly interested in the Overcontrolled-Hostility and Defensiveness scales of the MMPI. She interviews 12 people who have already been identified as serial killers. Their socres on the Overcontrolled-Hostility scale are recorded here:
69 84 56 89 47 63 86 58 74 35 71 60
1. Which of the following is a Possible value for the range?
a. 54
b. 22
c. 66
d. 79
2. Their scores on the Defensiveness scale are given here:
38 70 35 42 26 87 74 61 69 46 63 25
Which of the following is a possible value for the range?
a. 33
b. 70
c. 53
d. 62
Answer: 1. a. 54
2. d. 62
Step-by-step explanation: <u>Range</u> is the difference between the lowest and the highest value.
To calculate it:
- Organize the numbers from lowest to highest;
- Subtract the last number with the first number of this organized data;
1. For the scores on the Overcontrolled-Hostility:
35 47 56 58 60 63 69 71 74 84 86 89
range = 89 - 35
range = 54
For the Overcontrolled-Hostility, a possible value for a range is 54.
2. For the Defensiveness scale:
25 26 35 38 42 46 61 63 69 70 74 87
range = 87 - 25
range = 62
For the Defensiveness scale, a possible value for a range is 62.
