What is F variate?
The F-variate, named after the statistician Ronald Fisher, crops up in statistics in the analysis of variance (amongst other things). Suppose you have a bivariate normal distribution. You calculate the sums of squares of the dependent variable that can be explained by regression and a residual sum of squares. Under the null hypothesis that there is no linear regression between the two variables (of the bivariate distribution), the ratio of the regression sum of squares divided by the residual sum of squares is distributed as an F-variate. There is a lot more to it, but not something that is easy to explain in this manner - particularly when I do not know your knowledge level.
What statistical test to run when comparing the effects of two dichotomous variables on a dependent variable Anova Manova Why would you choose it?
If there are only two variables, then the dependent variable has only one variable it can depend on so there is absolutely no point in calculating multiple regression. There are no other variables!
What are independent and dependent variables in science?
Dependent variable is the variable that can be measured. However, the independent variable is the variable that changes in the two groups.
What is an alternating function?
An alternating function is a function in which the interchange of two independent variables changes the sign of the dependent variable.
What are the advantages of regression over correlation?
Correlation is a measure of association between two variables and the variables are not designated as dependent or independent. Simple regression is used to examine the relationship between one dependent and one independent variable. It goes beyond correlation by adding prediction capabilities.
What are the two important variables in a research title?
Dependent and Independent variables
What are the two types of variables in an experiment?
The two types of variables in an experiment are independent variables, which are controlled by the experimenter and can be manipulated, and dependent variables, which are the outcome or response that is measured in the experiment and may change in response to the independent variable.
Can you have two dependent variables?
It is generally not recommended to have two dependent variables in a single analysis, as it can complicate the interpretation of results. It is usually clearer to analyze each dependent variable separately in order to understand the relationship with the independent variable. If the dependent variables are closely related, consider creating a composite score or index to represent the construct.

What are the merits and demerits of multiple line graphs?
The main advantage is that it allows you to see how different dependent variables change according to changes in the same "independent" variable. It is relatively simple to use two vertical axes for the dependent variables, but the degree to which the two axes relate to one another is arbitrary. Furthermore, if the ranges of the dependent variables are very different the chart becomes unreadable.
How many manipulated variables does a controlled experiment have?
It can have as many as it needs. You can even change different variables at the same time and study their individual influence with proper statistical tools in many type of experiments.
When the ratio of two variables is constant their relationship can be described as what?
dependent
Why use partial differential equations?
A functional relation can have two or more independent variables. In order to analyse the behaviour of the dependent variable, it is necessary to calculate how the dependent varies according to either (or both) of the two independent variables. This variation is obtained by partial differentiation.
What are dependent and independent variables and how are they usually related to each other in a problem or situation?
a DEPENDENT variable is one of the two variables in a relationship.its value depends on the other variable witch is called the independent variable.the INDEPENDENT variable is one of the two variables in a relationship . its value determines the value of the other variable called the independent variable.
In psychology what is a correlational study used to determine?
A correlational study is used to determine the relationship between two variables. It shows whether and how two variables change together, but does not establish causation.
