Learning Objectives

• Be able to score two different types of data and organize that data for analysis.
• Calculate (with a calculator) the mean, median and mode for the data sets that are constructed.
• Use SPSS to provide mean, median and mode for each of the data sets.
• Make a graph of the distribution of scores for each data set.

Materials Needed

1. Calculator
2. Titan Net user ID and password
3. Raw data in the form of Data Sheets from the Mood and Attitudes
   
4. Calculator and statistical formula [Bring your own!].
5. Microcomputers with SPSS

Instructions

Practice: Part 1

1.  The data from page 10 in your text are repeated below.  Using your calculator find the mean, median and mode.

2.  Use SPSS to calculate the same statistics as in #1.

Class Experiment:  Part 2

1.  Obtain one of the data sets from the experiment we conducted in Lab, The first variable you should code is the participant number.  Call it parnum.   There are two category variables that are identified in the paragraph describing the person.  The first is gender.  You need to make a variable called  gender (1= male; 2 = female).  The second category variable is the agency condition.  Call it agency and give it a value of 1 for "caused the circumstance to happen) and 2 for "was caused by another person.

The dependent variables to be analyzed are the emotion rating terms for each adjective on the checklist.  They start with "admired" and go through "vigourous".

2.  Share the work by organizing the data  and have each member of your team enter a set of ratings into an SPSS spreadsheet.  Be sure to enter the Particiipant number into the first column .

3. Essay scoring.  Each member of the team should read all the essays.  Then you should read them again looking for the variables that should be coded.  Once you have identified three variables that could be coded, write up an operational definition for each one.  Identify the scale of measurement that you are usings.  After your instructor approves the definition have each member of your team code the essays on the three variables. 

4. Emotion Adjective Rating Scales.  Calculate a dominance subscale by summing the scores from the following adjectives.  Use SPSS to create the scale.
 

5.  Calculate the mean, median and mode of  the dependent variables you have coded for your data set (dominance, subordinate and the three variables that you created for coding the essays).

6.  The table below is one way to organize the data in SPSS. The calculated scale scores for the emotion rating scales will be added after you've input the raw data.

parnum	gender	agency	admired	amazed	antagonistic	beligererant	bewildered	...	vigorous
1	1
2	1
...	1

6.  Make graphs of the frequency distributions for each of the dependent variables you analyzed.  Figure 2.1 in the text (page 37) shows four alternative ways to graph the frequency of the example data. [Hint: Different team members can be responsible for different variables. Make graphs for scale scores and not individual adjective ratings.]

7.  By the end of lab you should have an electronic report of descriptive statistics and  graphs for the three essay  measures and for the twoemotion subscales. Use the statistics to describe the behavior of your part of the sample.
