Dependent variable refers to the variable being tested and measured in an experiment or study, which is expected to change as a result of changes in the independent variable.
The dependent variable is usually expressed as y or y’ (the estimated amount of y) and the amount is referenced on a graph’s y-axis. (An independent variable is expressed as x and is referenced on a graph’s x-axis.) Hence the equation for the monthly electricity cost will be y ...
If X and Y are dependent but Var(X) = Var(Y), find Cov(X + Y, X - Y). Explain what a "lurking variable" is. How do they impact statistics? True or false? The independent variable is the variable you wish to explain.
In computing, a dependent variable is any variable whose value, output or functioning depends on two or more independent variables. Advertisements A dependent variable is used in computer programming to represent a value, process, function or entity within the programming paradigm/context/architecture...
Regression Analysis: Analysis that models the link between two or more variables is known as regression. Regression analysis is widely used in predictive modeling to show how a dependent variable is related to one or more independent variables. Multivariate Statistical Analysis: In this type of Analy...
Cluster analysis can be a powerful data-mining tool to identify discrete groups of customers, sales transactions, or types of behaviours.
The dependent variable is a variable whose value is determined by the quantity another variable takes. For instance, in the equation y = 2x + 3, x can take any value, like 1, 2, 3. However, the value of y will depend on the value of x. So, if x = 1, y will become 5, and...
providing a visual demonstration of the relationship between the data points. Each point of data represents the relationship between a known independent variable and an unknown dependent variable. This method is commonly used by statisticians and traders who want to identify trading opportunities and tre...
For instance, in measuring the effect of stress on a person’s heart beat rate, stress would be used as an independent variable while the heart beat rate would serve as the dependent variable. Stress levels can be manipulated directly as the change in heart beat rate is monitored or ...
