Readers ask: What Is A Confounding Variable In Social Science?

A confounding variable is an “extra” variable that you didn’t account for. They can ruin an experiment and give you useless results. A confounding variable can have a hidden effect on your experiment’s outcome. In an experiment, the independent variable typically has an effect on your dependent variable.

What is a confounding variable example?

A confounding variable is an outside influence that changes the effect of a dependent and independent variable. For example, if you are researching whether a lack of exercise has an effect on weight gain, the lack of exercise is the independent variable and weight gain is the dependent variable.

What is meant by confounding variable?

A confounding variable (confounder) is a factor other than the one being studied that is associated both with the disease (dependent variable) and with the factor being studied (independent variable). A confounding variable may distort or mask the effects of another variable on the disease in question.

What are confounding variables in a study?

Confounding variables are the stowaways in a research study that can result in misleading findings about the relationship between the independent variable (IV), the input in the study, and the dependent variable (DV), the results of the study.

How do you identify a confounding variable?

If there is a clinically meaningful relationship between an the variable and the risk factor and between the variable and the outcome (regardless of whether that relationship reaches statistical significance), the variable is regarded as a confounder.

Is gender a confounding variable?

Hence, due to the relation between age and gender, stratification by age resulted in an uneven distribution of gender among the exposure groups within age strata. As a result, gender is likely to be considered a confounding variable within strata of young and old subjects.

What are the different kinds of variables?

Types of variables

  • Independent variables. An independent variable is a singular characteristic that the other variables in your experiment cannot change.
  • Dependent variables.
  • Intervening variables.
  • Moderating variables.
  • Control variables.
  • Extraneous variables.
  • Quantitative variables.
  • Qualitative variables.

Is time a confounding variable?

Time-varying confounding occurs when there is a time-varying cause of disease that brings about changes in a time- varying treatment (2, 3). Time-varying confounding affected by prior treatment occurs when subsequent values of the time-varying confounder are caused by prior treatment (4).

What are the two response variables?

One response variable is the amount of time visiting the site. This response variable is quantitative. One response variable is the amount spent by the visitor. This response variable is quantitative.

What is a lurking variable in statistics?

A lurking variable is a variable that is not measured in the study. It is a third variable that is neither the explanatory nor the response variable, but it affects your interpretation of the relationship between the explanatory and response variables.

How do you address a confounding variable?

There are several methods you can use to decrease the impact of confounding variables on your research: restriction, matching, statistical control and randomization. In restriction, you restrict your sample by only including certain subjects that have the same values of potential confounding variables.

Which of the following best describes a confounding variable?

Which of the following best describes a confounding variable? A variable that affects the outcome being measured as well as, or instead of, the independent variable.

How do confounding variables affect a research study?

Since a confounding variable is a 3rd factor that is not accounted for in a research process, it can affect an experiment by producing inaccurate research results. For example, it can suggest a false correlational relationship between dependent and independent variables.

What is an example of an extraneous variable?

For example, if a participant is taking a test in a chilly room, the temperature would be considered an extraneous variable. Some participants may not be affected by the cold, but others might be distracted or annoyed by the temperature of the room.

What is the difference between confounding and extraneous variables?

Extraneous variables are those that produce an association between two variables that are not causally related. Confounding variables are similar to extraneous variables, the difference being that they are affecting two variables that are not spuriously related.
