Online Assignment 2 — Public attitudes toward lawyers

Exercise A

In this exercise, we need to create three new variables to answer these three questions:

1.    What percentage of respondents claim that they did not have control over how their lawyer handled their case and that they were not treated fairly by their lawyer?

2.    What percentage of respondents claim that they did not have control over how their lawyer handled their case or that they were not treated fairly by their lawyer?

3.    What percentage of respondents claim that they did have control over how their lawyer handled their case and that they were treated fairly by their lawyer?

Variable names:      nocontrol_and_unfair

nocontrol_or_unfair

control_and_fair

Variable labels:       You decide, but you must have variable labels.

Value labels:           All three variables should use 0/1 values, where

0 = No

1 = Yes

Decimal places:       0

1.    Run frequencies for the three new variables, and print the output for each.

2.    What percentage of respondents claim that they did not have control over how their lawyer handled their case and that they were not treated fairly by their lawyer?

3.    What percentage of respondents claim that they did not have control over how their lawyer handled their case or that they were not treated fairly by their lawyer?

4.    What percentage of respondents claim that they did have control over how their lawyer handled their case and that they were treated fairly by their lawyer?

Exercise B

In Online Assignment 1, we created the composite variable “attitude” by summing up the three individual attitude variables. This method of aggregating treats all of the variables as though they have the same seriousness, or weight. However, what if, for example, we believe that the trustworthiness of a lawyer is a more serious issue than whether they are perceived as being coldhearted and ruthless? To represent varying levels of importance, we have to weight our variables. In this exercise, we are going to create a new composite variable for attitudes toward lawyers that is weighted as follows:

1.    “ruthless” – not weighted.

2.    “money” – values multiplied by 2.

3.    “nottrust” – values multiplied by 3.

Note: don’t get caught up in terminology. Your textbook does not talk about weighting (yet!). What is important in this exercise is that you figure out how to carry out the computation.

Variable name:         attitude_wght

Variable labels:         You decide, but you must specify a variable label.

1.    Run descriptives on the new variable, and print the output.

2.    What is the mean score for our new weighted variable?

3.    What is the 95% confidence interval for the mean?

Exercise C

Suppose we are potentially interested in using several variables as dependent variables.  Moreover, the analyses that we want to run require that the dependent variable be approximately normally distributed. In this exercise, we want to examine the following three variables:

1.    “nottrust”

2.    “money”

3.    “attitude”

For each variable:

a.    assess its normality;

b.    if you find a problem with normality, remedy it as best you can.

For both (a) and, if necessary, (b), include an explanation of what you did and how you arrived at your conclusions. Also include printouts of the results that led to your conclusions.

Please type (or write) your answers in the space below (Use as much space as you need. Feel free to go on to another page if you need to).

Exercise D

We want to look at your dataset. To let us do that, please do the following:

1.    Sort your dataset to that it is arranged from the smallest to the largest Identification Number.

2.    Scroll to the right, so that the variable “nage” is the first variable showing (that is, until “nage” is the first column on the left hand side of the screen).

3.    While you are looking at your dataset on the screen, press the Print Screen key. On most computers, this key has “Prnt Scrn” on it. Your computer may be a bit different. Pressing this key does not actually print, but rather, causes the computer to capture an image of whatever is on the screen at the time.

4.    Go to your online assignment file, or to a new word processing page, and paste the screen image into your file. This is your answer for Exercise D.

5.    Save the changes you’ve made to your file. You may want to save the file as a new name, do distinguish it from the old file (in the event you’ve made any mistakes).
