Is the dependent variable measurable?
The measurable variable, as the name suggests, is the variable that is measured in an experiment. It is the dependent variable (DV), which depends on changes to the independent variable (IV). Any experiment studies the effects on the DV resulting from changes to the IV.
How do you identify independent and dependent variables in research?
You can also think of the independent variable as the cause and the dependent variable as the effect. When graphing these variables, the independent variable should go on the x-axis (the horizontal axis), and the dependent variable goes on the y-axis (vertical axis). Constant variables are also important to understand.
What makes a good dependent variable?
Stability is often a good sign of a quality dependent variable. If the same experiment is repeated with the same participants, conditions, and experimental manipulations, the effects on the dependent variable should be very close to what they were the first time around.
What are dependent and independent variables in statistics?
You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable.
What is the key difference between independent and dependent variables?
A dependent variable is a variable whose variations depend on another variable—usually the independent variable. An Independent variable is a variable whose variations do not depend on another variable but the researcher experimenting.
Is gender dependent or independent variable?
An independent variable is used in statistics to predict or explain a dependent variable. For example, Age and Gender might be used as independent variables to predict the age of death or life expectancy (dependent variables).
Is year an independent variable?
The independent variable here is the YEAR and it is plotted on the horizontal axis. The dependent variable is the AVERAGE HEIGHT and this is plotted on the vertical axis. The height is a dependant variable because we are trying to determine a relationship between the year and the height.
Is BMI a dependent or independent variable?
For example, suppose we want to assess the association between total cholesterol (in milligrams per deciliter, mg/dL) and body mass index (BMI, measured as the ratio of weight in kilograms to height in meters2) where total cholesterol is the dependent variable, and BMI is the independent variable.
Is body weight an independent variable?
Calorie intake is your independent variable and weight is your dependent variable. You can choose the calories given to participants, and you see how that independent variable affects the weights.
