If an experiment compares an experimental treatment with a control treatment, then the independent variable (type of treatment) has two levels: experimental and control. If an experiment were comparing five types of diets, then the independent variable (type of diet) would have 5 levels. In general, the number of levels of an independent variable is the number of experimental conditions.
The mean level of the independent variable refers to the average value or level of the variable across all participants or cases in a study. It represents the central tendency of the independent variable within the sample.
Levels refer to the different kinds or amounts of the independent variable.
For example, you might be looking at the effect of varying dosages (say low and high dosages) of a drug on performance of a behaviour. Your independent variable is the drug, your levels are the dosages (low and high).
So you have 1 independent variable with 2 levels.
Getting more complicated, you might look at the differences between genders. So this would add 1 more independent variable with 2 more levels (male and female).
Hope this helps!!

Why do you called independent variable independent variable?
The independent variable is called independent because it is the variable that is being manipulated or changed by the researcher to observe its effect on the dependent variable. It is independent of any other factors in the experiment because its values are determined by the researcher's actions.
Independent variable and dependent variable for colours effect on emotion?
If you are doing an experiment to find colour's effect on emotions, the coulour would be the independent variable because it is what you are controlling, and the emotions would be the dependent variable because they are the results.
What are the elements of experiments and what kinds of variables are there?
The elements of experiments include the independent variable (manipulated by the researcher), dependent variable (outcome being measured), control group (not exposed to the independent variable), and experimental group (exposed to the independent variable). Variables can be independent (controlled by the researcher), dependent (measured to see the effect of the independent variable), or extraneous (unintended variables that can affect the results).
Does the dependent variable depend on the independent variable?
Yes, the dependent variable is influenced by changes in the independent variable. The relationship between the two variables is typically investigated through statistical analysis to determine the extent of this influence.
Dependent and independent variables in biology?
In biology, the dependent variable is the factor being measured or tested in an experiment, and its value depends on the independent variable. The independent variable is the factor that is manipulated or controlled by the researcher to observe its effect on the dependent variable. For example, if studying the effect of different fertilizer amounts (independent variable) on plant growth, the plant growth measurements would be the dependent variable.
Does independent and Dependent variable's mean in math?
An independent variable is a variable that isn't affected by something else. A dependent variable is a variable that's affected by changes in the independent variable.
What does depemdent variable mean in science?
a variable that depend on the independent variable
What do indepedent variable mean?
Independent variable is the variable that you change in an experiment.
What does dependent variable and independent variable mean in math?
An independent variable is a variable that isn't affected by something else. A dependent variable is a variable that's affected by changes in the independent variable.
What is does independent variable mean in math terms?
The independent variable is the thing that stays the same throughout the problem.
What are independent and dependent variables in Asch's experiment on conformity?
Independent variable: Number of confederates providing the wrong answer Dependent variable: Level of conformity
What does independent variable mean in math?
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.
What does iv mean in scientific method?
Independent Variable, its the variable that you can manipulate or change.
What does iv and dv mean?
The independent variable is what you measure and the dependent variable is what you change
What does independent variable and dependent variable mean in science?
It means that they are not supposed to be together.
In an experimental investigation the variable that the researcher changes or manipulates in order to see its effects is called the?
Independent variable, is variable that the experimenter manipulates
What level of measurement is grade level?
· Dependent variable ( student's academic achievement ) : It depend on the way that we use it to write the score (if we write it as a letter it will be an ordinal ,but if we write it as number it will be an interval). · Independent variable ( intelligent ) : Interval, · Independent variable ( attention ) : Interval,
