 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 attributesmale/femaleclass
 refers to surface attributes that can be easily quantified, objectivityprecision, generalizing
 This what you need:
 characteristics; qualities of a person or thing
 (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.

Dependent variable → changes as a result of independent variable

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.

control 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.

Moderating Variables → are moderating variables that we seek to control by holding them constant in our research design

Independent variable → changes as a result of independent variable
