Document Summary
A concept that can take on multiple values (ie: that can vary) Attributes= the values or categories of a variable. Research questions are often expressed in terms of the dependent variable because this is what we are trying to explain. Comes between the independent and dependent variable and explains the connection between them. Marital status ( + ) social integration ( - ) suicide (+) = positive relationship ( - )= negative relationship. A tentative statement of a relationship between two variables. Negative evidence is given more importance- logic of disconfirming hypothesis. Quantitative researchers frame hypotheses in terms of a null hypothesis-that there is no relationship or association between two variables. Hypothesis: students who attend every class have higher grades than students who do not. Null hypothesis: this is no relationship between class attendance and students" grades. Alternative hypothesis: class attendance has a positive effect on students" grades (**if null hypothesis is true, the alternative hypothesis is false)
