Thursday 2 February 2006:

 

Dipping our toe into the quantitative

 

We’re going to work with the data for ENVELOPE

I’ve ‘cleaned’ this data set.

            What that means

 

LOGON AND ACCESS our class via webpage

 

a. pull down cleaned-up data  and open and read envelop-tape-r.txt

b. download ENVdataNo-0r.xls to desktop

 

 

Task 1: Sum the ages -- put cursor below last age in column and click the Sigma

 

Task 2: Average of ages – erase the sum. Put cursor in same place, pull down the arrow beside the Sigma and click average

 

Task 3:  Highlight and copy all the a-file, and scroll down and paste it below all the data, pasting around line 88

 

Task 4:  Descriptive picture

Highlight the numbers for age and click Insert – try a pie chart. Now try a bar chart. What did you learn?

 

Make a pie chart for the numbers under Fam_class

 

Now recode the data in fam class: you have

         Class  number

               1    2

               2    5

               3    2

               5    1

 

Why don’t you put the 4 in?

 

Retype this new data to the spread sheet

Highlight the data, including the titles

Now insert a pie chart

What did you learn?

 

Task 5: Look at what could be interesting questions to ask:

Age x friendly, or what else?

Class x

Locale x

Moth ed x

Fath ed x

 

Choose and graph a set. Do what you have to do to make meaning.

 

Task 6: a jump to spss

Open spss (maximize the novell programs and select spss; it loads slowly)

 

Close the window that asks what you want to work with – if it opens

Pull down OPEN under FILE

You’re going to open DATA

From the DESKTOP

Kind of file: EXCEL

And yes, you want it to read the variable names

 

Pull down ANALYZE

To DESCRIPTIVE

Do Frequencies using Mother’s Ed

Look at what the table tells you

Get rid of that output window by Xing the top right corner

 

Task 7: chi-square via crosstabs

 

Pull down ANALYZE,

To DESCRIPTIVE

Select CROSSTABS

In the window, put Father’s Ed in the first and Friendly in the second

Click to check “Statistics”

Select chi square

Click OK

Save it to the desktop or pull it down

Redo, by putting Father’s Ed back and putting FamClass in the first window

 

We’ll discuss what you’ve just learned from reading the two tables

 

 

Task 8: correlations

Let’s see if  family class, perception of locale, mother’s education and father’s education are connected to/associated with the perception of a speaker as friendly.

Pull down ANALYZE and select CORRELATE and choose bivariate. In the window, check Pearson and Two-tailed. Check ‘flag significant correlations’.

 

Click on each of the 5 variables so that they go into the Variable window. Click OK

 

We will discuss what you just learned from reading the table.

If we have time, we’ll run the same variables against POLITE.

 

And that will be enough for tonight --
