INT 222 Social Science Statistics

Task:

Be sure you've clicked on the link in the announcements and downloaded SPSS because if you have not this is not going to work.
Save the data file to your desktop or documents(right click, then save). Open the document by double clicking on it or open SPSS and find the document.

SPSS may take some time to fully load.

While you are looking at the data take a moment and familiarize yourself with some of the basic functionality. (This should look like what you viewed in the video)  Note that the data can be viewed in two different ways, the Data View and the Variable View (the tabs on the bottom). You will primarily use the Data View for this project.

Once you have the data open, click on Analyze, then Descriptive Statistics, Descriptives, put IMR_2000 into the box, then make sure the following boxes are checked: Mean, minimum, maximum, standard deviation and range. Click Continue then click OK. You should see the output now.

If you view the Basic Statistics video below it will show you how to perform the steps below as well as other options in SPSS.

Go back to Analyze, Frequencies and put IMR_2000 in the box. Make sure the Display Frequency Tables is not clicked. Now click on Statistics and check the boxes for median, quartiles, maximum, and minimum. Click Continue and then click ok. You should see the output now.
Go to Graph, Legacy Dialogs, Boxplot, Click Simple and make sure the Summaries of Separate Variables is selected. Click Define and put IMR_2000 in Boxes Represent and click OK. Once you completed the assignment copy your output and paste it either into the submission below or into a word document and then attach it.

It is time to choose a variable from the variable list to use in your EDA project.
These last two assignments are actually part of the EDA project, so be sure to keep copies to use in the project. HOWEVER, after getting your results you might decide to change variables.

For the last part of the EDA project, you will need to do a scatterplot of your two variables using SPSS. Since you are now pretty familiar with SPSS this should not be too difficult. There is also a video that goes through these steps posted below.

Open your data file, and click on Graphs, Legacy Dialogs, Scatterplot and pick Simple. Put your earlier time period variable in the X-axis and your later time period in the Y-axis, set your markers by IncomeCat, and label your cases by country. Make sure to click the options to have the labels displayed. Click Ok. Look at your graph. We want to add a straight line from the origin (bottom left corner) to the top right corner.  To do this we will need to put in line y=x on top of the graph as a reference. There is a way to do this through editing which I show you in the video.

All your data points that fall on the line represent countries whose value has not changed over the two time periods you are observing. Points that fall below the line have decreased over time, i.e., their value was higher in the earlier time period. Points above the line have increased over time, i.e., their value is higher in the later time period.
Copy and paste your graph output into a word document and submit the assignment below then write a couple of sentences about your observations.
