Unit 6 Multiple Regression
Assignment 6
Calculating and interpreting Multiple Regression:
For this assignment you will be presented with a data set that includes 4 variables.
The data set contains four variables:
1. Self-Reported Criminality (Number of times a person has committed a crime in the past month.
2. Anti-Social Personality Score (A score from a psychological test designed to measure anti-social personality). The score ranges from 1-10. With a higher number representing a higher level of antisocial personality) Meaning those who score low do not have an antisocial personality, but high scores may.
3. Age (The respondents cu
ent age in years).
4. Social Class (The respondents social class: 1= lower class, 2 = middle class, 3 = upper class).Since this is a categorical variable it will need to be dummy coded. However, I already did this for you! So you do not need to recode.Remember your interpretation of b will be different than it is for the continuous variables.
Your assignment is to run and interpret the results form a regression with self-reported criminality as the outcome variable, and Anti-Social Personality Score, Age, and Social Class as the predictor variables. You should use the forced entry method for the regression.
Data Set
You can Download the data set to use for this assignmentUnit 5.4 Homework Data.sav.
Using this data please do the following:
Imagine that you hypothesize the following:
· There is a positive relationship between antisocial personality scores and criminality.
· There is an inverse relationship between age and criminality.
· Lower class individuals commit more criminality than upper and middle class individuals.
Use multiple regression to test these hypotheses while controlling for the other variables. In other words run a regression with all of these variables included.
Please do the following.
1. First answer the following question. What would be the benefits of conducting a multiple regression rather than simply running more than one bivariate regression?
2. Run a multiple regression with all of the variables in the data set included:
a. You should test the assumptions and report your findings: Make sure to check the following assumptions. For the assignment test each assumption and report the results. Indicate whether the data meets each of the following assumptions and diagnostic tools:
i. Outliers
ii. No Zero Cells
iii. Linearity
iv. Level of Measurement
v. Normally Distributed E
or Term
vi. No Auto Co
elation
vii. Multicollinearity
. For this second part assume that you met all of the assumptions to run a multiple regression (even if you did not). Report the results for the regression you ran as you would report them in a journal article. Make sure you include all relevant information. You should report the results for the following:
i. The F test (And its Sig value)
ii. R2
iii. B (slope) with significance for each variable
iv. Beta for each variable (Rank order the Betas)
Note: Like the previous assignments the more detail you provide the better. If you produce any tables or graphs you should consider cutting and pasting them into your .rtf document.
As usual you should summit it as a word doc or .rtf file.

Assessment Details
Case Study
Robotic surgery sounds like the ultimate in safe, efficient and effective 21st-century health care.
Instead of a surgeon's potentially fallible human hand, you have a robot with its precision-built
mechanical arms able to perform micro-accurate procedures on tissues deep within the body.
With robot-assisted surgery, the surgeon sits at a nea
y console with a 3D view of the surgical
site. Computer technology translates their hand movements into precise manoeuvres of the
instruments. If the surgeon's hand develops a tremor, the computer system knows to ignore it.

The technology also means surgeons can use finer instruments that cause less damage to the
ody. In turn, this should reduce blood loss and the need for blood transfusions - and mean that
patients recover more quickly. With this kind of promise, little wonder that multi-million-pound
obot machines are performing ever more operations across Britain.
The technology, which was first used in 2000, is employed increasingly in intricate surgery such
as hysterectomy, gallbladder removal and repair of damaged heart valves.
But while for many patients robot surgery will have been entirely smooth, the technology is not
isk-free. And leading experts are now voicing growing fears about its safety and effectiveness,
warning of a growing human toll.
Good Health has learned of one particularly alarming case in which a man suffered grievous
injuries from a robotic procedure that nearly killed him when it went wrong.
The patient, who can't be named for legal reasons, was suffering from prostate cancer and
ecently had his prostate gland removed by keyhole surgery using robot technology. His solicitors
say the remote camera attached to the robot arm damaged the man's bowel, leading to severe
infection, organ failure and cardiac a
est (Nash, 2013).
Ethical dilemma:
To what extend are IT professionals responsible for the surgery accuracy of robots they
program?
Requirements
This is an individual task. Students are required to write two (2) forum posts in moodle which
provide an analysis of an ethical dilemma associated with robotic assisted surgery from a
software developer’s perspective.
• Post 1: In post one (1) students should provide an answer to the ethical dilemma through
the lens of each of the ethical theories presented in lectures. These include utilitarianism,
deontology, social contract theory, character-based ethics1. The post should be
approximately two to three pages long XXXXXXXXXXwords). It should contain a
ief
overview of each of the four ethical theories, and a discussion and proposed solution for
the dilemma, from each of the four ethical theoretical viewpoints. The discussion should
show an analysis and synthesis of research undertaken and your own ideas.
• Post 2: In post two (2) students will apply ACS code of ethics2 in order to solve the ethical
dilemma. The post should be approximately one page long XXXXXXXXXXwords). The
discussion should show an analysis and synthesis of research undertaken and your own
ideas.
Each post should contain a bibliography containing authentic academic literature. Post 1
(approximately 6–10 references), and Post 2 (approximately 4–8 references). Gather these
eferences from various sources such as the Internet, assigned textbooks and readings etc. For
assistance with in-text referencing and formatting your reference list in APA format, see the link to
General Guide to Referencing provided.
