Statistics for the Behavioral Sciences by Frederick J. Gravetter, Larry B. Wallnau ISBN 10: 1305504917 ISBN 13: 9781305504912

Statistics is one of the most practical and essential courses that you will take, and a primary goal of this popular text is to make the task of learning statistics as simple as possible. Straightforward instruction, built-in learning aids, and real-world examples have made STATISTICS FOR THE BEHAVIORAL SCIENCES, 10th Edition the text selected most often by instructors for their students in the behavioral and social sciences. The authors provide a conceptual context that makes it easier to learn formulas and procedures, explaining why procedures were developed and when they should be used. This text will also instill the basic principles of objectivity and logic that are essential for science and valuable in everyday life, making it a useful reference long after you complete the course.

General Instructions

for Using SPSS

APPENDIX

D

The Statistical Package for the Social Sciences, commonly known as SPSS, is a computer

program that performs statistical calculations, and is widely available on college campuses.

Detailed instructions for using SPSS for specific statistical calculations (such as

computing sample variance or performing an independent-measures t test) are presented

at the end of the appropriate chapter in the text. Look for the SPSS logo in the Resources

section at the end of each chapter. In this appendix, we provide a general overview of the

SPSS program.

SPSS consists of two basic components: A data editor and a set of statistical commands.

The data editor is a huge matrix of numbered rows and columns. To begin any

analysis, you must type your data into the data editor. Typically, the scores are entered into

columns of the editor. Before scores are entered, each of the columns is labeled “var.” After

scores are entered, the first column becomes VAR00001, the second column becomes

VAR00002, and so on. To enter data into the editor, the Data View tab must be set at the

bottom left of the screen. If you want to name a column (instead of using VAR00001),

click on the Variable View tab at the bottom of the data editor. You will get a description

of each variable in the editor, including a box for the name. You may type in a new name

using up to 8 lowercase characters (no spaces, no hyphens). Click the Data View tab to

go back to the data editor.

The statistical commands are listed in menus that are made available by clicking on

Analyze in the tool bar at the top of the screen. When you select a statistical command,

SPSS typically asks you to identify exactly where the scores are located and exactly what

other options you want to use. This is accomplished by identifying the column(s) in the

data editor that contain the needed information. Typically, you are presented with a display

similar to the following figure. On the left is a box that lists all of the columns in the data

editor that contain information. In this example, we have typed values into columns 1, 2,

3, and 4. On the right is an empty box that is waiting for you to identify the correct column.

For example, suppose that you wanted to do a statistical calculation using the scores

in column 3. You should highlight VAR00003 by clicking on it in the left-hand box, then

click the arrow to move the column label into the right hand box. (If you make a mistake,

you can highlight the variable in the right-hand box, which will reverse the arrow so that

you can move the variable back to the left-hand box.)
