a) Governor-Mean is 43 and Standard deviation is 5.916
CEO- Mean is 44 and standard deviation is 10.954
b) In order to calculate the mean or average for the governors and CEO’s, I added together all the figures and divided that sum by 4 since there are 4 numbers. Calculate the standard deviation by getting the average of the average (mean) of the numbers. So the average of 43 for the governors is 5.916 and the average of 44 for the CEO’s is 10.954. c) Judging from the results we can see that the CEO’s have bigger desks than the governors. The difference between mean and standard deviation is that mean is the sum of the scores divided by the number of scores and standard deviation is the square root of the average of the squared deviations from the mean. 21

a) z (340) = (340-300)/20 = 40/20 = 2
b) z(310) = (310-300)/20 = 10/20 = .5
c) z(260) = (260-300)/20 = -40/20 = -2
Raw Scores
d) z = 2.4 score = 300 + 20 x 2.4 = 300 +48 = 348
e) z = 1.5 score = 3000 + 20 x 1.5 = 300 + 30 = 330
f) z = 0 , score = 300
g) z = -4.5 , score = 300 + 20 x -4.5 = 300 -90 = 210
15. z(81) = (81-50)/2 = 31/20 = 1.55, z(6.4) = (6.4-0)/5 = 1.28. So, the verbal ability test is higher. You need to figure this out by standardizing both scores by converting them to Z scores. 22.

...person is supposed to choose one quickly. There is a 50/50 chance of picking a black person over a white person in the pictures and there is a 50/50 chance of picking a gun over a tool. This is actually a test of prejudice and perception.

14. Transformation of z scores and raw scores
a. Give the Z scores for the following raw scores:
raw score Z score
340 Z= {(340-300)]/20= 2
310 Z=[(310-300)]/20= .5
260 Z= [(260-300)]/20= -2
b. Give the raw scores for...

...Behavioral and Social/Cognitive Approaches to Forming Habits
As children, humans learn right from wrong through either punishment or praise by their parents. Depending on the action and accompanying reaction from their parents, a child may develop habits. According to Psychology Today, a habit is defined as an acquired behavior pattern regularly followed until it has become almost involuntary (Psychology Today, 2012). Some examples of habits are looking both ways before crossing the...

Research, Statistics, and Psychology
Humans and animals may have a vast number of similarities, but the one thing that sets humans apart is the unique ability to question. When psychologists look to find the answers to questions, they often turn to statistics. Gathering research to devise rational explanation is important to psychology; it is not only important, but the manner in which...
