This section provides step by step instructions on creating a SPSS data file.
to be used when study has one independent variable with two and only two levels, (and the subjects at each level were randomly assigned to that level) and the dependent variable is measured by an interval or ratio scale
• Repeated Measures (Matched Groups) t test (.pdf 104k)
to be used when study has one independent variable with two and only two levels (and the subjects at each level are the same people or, if not the same people, have been in some way linked or paired with one another) and the dependent variable is measured by an interval or ratio scale
to be used when you wish to determine if a relationship exists between two continuous variables (variables that are measured by either an interval or ratio scale). Both continuous variables might be dependent variables, one might be conceived of as an independent variable and the other as a dependent variable, or both might be conceived of as independent variables in the study
to be used to determine if a relationship exists between two sets of data if one or both are in the form of ranks (ordinal scale data)
to be used to evaluate how well a single independent (predictor) variable predicts a response on a dependent (predicted or criterion) variable.
to be used to determine whether two variables are linearly related when the effects of a third (or more) control variables are held constant.
to be used to assess the relationship between a dependent (predicted) variable and several independent (predictor) variables.
to be used when study has one independent variable with three or more levels, (and the subjects at each level were randomly assigned to that level) and the dependent variable is measured by an interval or ratio scale
to be used when study has one independent variable with three or more levels and the same or matched subjects have been used in each level of the independent variable and the dependent variable is measured by an interval or ratio scale

to be used when study has two independent variables (regardless of the number of levels of each independent variable), when different subjects have been randomly assigned to the various conditions of the experiment and when the dependent variable is measured by an interval or ratio scale
to be used when study has two independent variables (regardless of the number of levels of each independent variable), and when the same subjects are in each condition of the entire experiment) and the dependent variable is measured by an interval or ratio scale
to be used when study has two independent variables (regardless of number of levels) where for one level of one of the independent variables the same subjects are in all levels of the second independent variable. Responses on the dependent variable are measured by either an interval or ratio scale
to be used when you wish to determine if a relationship exists between two discrete variables (i.e., between an independent variable with different levels and a dependent variable measured on a nominal scale) Alternative Chi-Square (.pdf 106k) for large data file and raw data Chi-Square for Goodness (.pdf 100k) of Fit
similar to an independent groups t-test, to be used when study has one independent variable with two levels and a dependent variable measured on an ordinal scale
similar to a repeated measures (matched pairs) t-test, to be used when study has one independent variable with two levels and a dependent variable measured on an ordinal scale. The same (or matched) subjects in the study participate in both conditions of the study
similar to a oneway between subjects ANOVA, to be used when study has one independent variable with three or more levels and a dependent variable measured on an ordinal scale
similar to a oneway repeated measures ANOVA, to be used when study has one independent variable with three or more levels and the same subjects are repeatedly measured and the dependent variable is measured on an ordinal scale
to be used in attitude scale construction and determine whether the items in a scale "hang" together and reliably measure the same construct. In order for the global scale to have good reliability, the Cronbach Alpha should minimally have a value of .7
This section provides instructions on creating master data sets for large data files. It also provides five examples of Data Analysis Procedures to answer five different questions about a data set.
Instructions are provided for the procedures involved in conducting analyses on only portions or subsets of data from an experiment. Look at procedures for answering question 5 listed
Instructions are provided for obtaining printout in the Mahar Hall 302/210 computer lab. Important information is provided pertaining to student costs for printout. Use the short form instructions whenever possible.
Instructions are provided for saving a data file on a 3 1/2 A drive.
Instructions are provided for exiting the program SPSS for Windows
Instructions are provided for logging off the computer presently being used.
Instructions are provided for using the Pine Mailer on the Main frame system (Rocky).
Instructions are provided for logging on to the desk top computers in Rooms 302 and 210 Mahar and for logging on to the main frame computer (Rocky) from the desktop computers in 302 and 210 Mahar.
