- a testable prediction used to see how something works or to solve a problem

- Many people have trouble remembering which is the independent variable and which is the dependent variable. An easy way to remember is to insert the names of the two variables you are using in this sentence in they way that makes the most sense. Then you can figure out which is the independent variable and which is the dependent variable: (Independent variable) causes a change in (Dependent Variable) and it isn't possible that (Dependent Variable) could cause a change in (Independent Variable).
- concept being investigated that is characterized by different attributes-male/female-class
- (Time Spent Studying) causes a change in (Test Score) and it isn't possible that (Test Score) could cause a change in (Time Spent Studying). We see that "Time Spent Studying" must be the independent variable and "Test Score" must be the dependent variable because the sentence doesn't make sense the other way around.
- It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does.
6 True/False questions
Example → concept being investigated that is characterized by different attributes-male/female-class
control variables → are moderating variables that we seek to control by holding them constant in our research design
Descriptive in Quantitative Methods → start as a hypothesis about something, explains a phenomenon and then test the hypothesis
Moderating Variables → are moderating variables that we seek to control by holding them constant in our research design
What's an independent variable? → An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age. In fact, when you are looking for some kind of relationship between variables you are trying to see if the independent variable causes some kind of change in the other variables, or dependent variables
Relationship Variables → A moderating variable is one that has an effect on the dependent variable, but is not related to or affected by the independent variable. Often times, as your text illustrates a moderating variable may be a categorical variable in which only one of the categories has an effect on the dependent variable such as gender, marital status or socioeconomic status. In other words the moderating variable effects the dependent variable, but it's effect is not influenced or Independent Variable Mediating Variable Dependent Variable caused by the independent variable.
