A confounding variable is an outside influence that changes the effect of a dependent and independent variable. This extraneous influence is used to influence the outcome of an experimental design. Simply, a confounding variable is an extra variable entered into the equation that was not accounted ...
What is a confounding variable? Confounding variables (a.k.a. confounders or confounding factors) are a type ofextraneous variablethat are related to a study’sindependent and dependent variables. A variable must meet two conditions to be a confounder: ...
The diagram below illustrates these two conditions. There must be non-zero correlations (r) on all three sides of the triangle. X1 is the independent variable of interest while Y is the dependent variable. X2 is the confounding variable. Thecorrelationstructure can cause confounding variables to...
Computers with faster CPUs might appear to last longer. One might quickly assume that a faster CPU directly ensures the computer’s longer lifespan. However, the third variable problem highlights the overall quality of other hardware components. Computers equipped with high-speed CPUs are often prem...
Controlling extraneous variables is an important aspect ofexperimental design. When you control an extraneous variable, you turn it into acontrol variable. Extraneous vs. confounding variables Aconfounding variableis a type of extraneous variable that is associated with both the independent and dependent...

For example, higher temperatures cause more people to buy ice cream and swim at the beach, increasing the opportunities for shark attacks. Hence, even though there is no relationship between ice cream sales and shark attacks, they tend to rise and drop together. The confounding variable of temp...

Even if we could dispose of such confounding factors, the fact would remain that maleness, per se, is not a cause. To explain the trend, we need to instead identify factors common to men, or at least suicidal ones. The same point applies to the comparatively high rates of suicide report...
