Work through the following questions using the SPSS Help Manual to become familiar with SPSS operations. This is a practice worksheet and no marks will be assigned.
 

1. The following data represent ten observations on the amount of October snow cover for Eurasia during the years 1980 - 1989 (in million km²):

Enter these values into an SPSS file. Name the variable SNOW and specify it as numeric with one decimal place. Save your data in a file called Snowdat.sav

2. In double-checking my notes with the original data source, I found two errors:

1. a case is missing - the second entry should be 12.0. Insert the new observation.
2. the number 1.9 should be 21.9 - change the entry. Save your changes.

3. Sort the data from lowest to highest.

4. Prepare a histogram of your data. Label the histogram: October Snow Cover for Eurasia: 1980 to 1989. Print the histogram.

5. Enter the following data in a new file. Specify the variables accordingly.

6. Use the calculator functions in SPSS to:

1. multiply the depth by a constant value (5) and save the new variable.
2. square the values in column 1 and save the new variable.
3. prepare a scatterplot of Class (Y axis) vs Depth (X axis).

7. Use the remaining lab time to explore the SPSS menu.
