regression analysis
Regression analysis is based on the assumption that the dependent variable is distributed according some function of the independent variables together with independent identically distributed random errors. If the error terms were not stochastic then some of the properties of the regression analysis are not valid.
In statistics, regression analysis is a statistical process for estimating the relationships among variables. It includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables.

You may get more ideas from wikipedia under regression analysis. You can do a regression analysis with as little as 2 x,y points- but is it meaningful? Requirements for valid or meaningful relationships can be subjective. However, in my opinion, if meaningful relationships are to be created using regression analysis, the following are important: a) The independent variable should have values that are independent (no relation exists between them). b) There should be a good rational or experimental basis for identifying the independent variables and the resultant dependent variable. c) Sufficient data should be collected in a controlled environment to identify the relationship. d) The validity of the relationship should easy to identify both visually and by numbers (see "goodness of fit" tests).
Possible maybe
True.

Simple regression is used when there is one independent variable. With more independent variables, multiple regression is required.

Before undertaking regression analysis, one must decide on which variables will be analysed. Regression analysis is predicting a variable from a number of other variables.
To perform regression analysis in SPSS: Open your dataset in SPSS. Go to "Analyze" > "Regression." Select the type of regression analysis (linear or multiple). Move the dependent variable to the "Dependent" box. Move independent variables to the "Independent(s)" box. Optionally, specify additional settings. Click "OK" to run the analysis. Interpret the results in the generated output. You can take professional help also. Experts can surely help you and assist you in performing such data analysis tasks.
