What is a confounding variable? What is the 'two lines perpendicular to the third line' theorem? What are contolled variables? Find the equation of the line between these two points A (0, 8) and B (-4, 0). What is the equation of a line that is parallel to y = -4x + 2...
What is a confounding variable? provide an example. If the coefficient of determination between two independent variables is 0.20, what is the VIF? If the independent variables explained less than 50% of the variation of the dependent variable, which of the following would be true? a. The coe...
Therefore, it is unclear whether the findings provided information about Internet gambling, diversity of gambling formats or time spent gambling. This study aims to fill in this gap and includes both diversity of gambling formats and time spent gambling as confounders to investigate the relationship ...
1 It occurs when an investigator tries to determine the effect of an exposure on the occurrence of a disease (or other outcome), but then actually measures the effect of another factor, a confounding variable. As most medical studies attempt to investigate disease etiology and causal ...

[解析]Psychologist Nina Strohminger at the University of Pennsylvania, who was not involved in the study, says she wants the effect to be real but cannot rule out some unknown confounding variable. And if real, she notes, it might be reversible by another nudge: “Easy come, easy go”. ...
External confoundingSpecification errorsModel testingThe residual dependent-variable variance in experiments is not "random error", as it is often assumed to be, but merely "unaccounted for variance", because what is random is inexplicable in terms of any possible set of independent-variables and ...
there may be a variable further upstream that impacts both of these. For example, smokers may drink more coffee, and smoking causes heart disease. In this case, smoking is aconfounding variablethat makes it more difficult to establish a causal relationship between coffee and heart disease. (In...
Explain what is a lurking variable. How does it compare to a confounding variable?Lurking versus Confounding Variable:There are some extraneous variables that tend to affect both the dependent and the independent variable(s) causing the relationship between them to become spuriou...
Scientific experiments use variables to help create a plan about what is being testing and how it is being tested. Common variables that each experiment need include control, independent, and dependent variables. Answer and Explanation:1 A conceptual variable is the idea of what needs to be measu...
