The variable that is used to explain or predict the response variable
is called the explanatory variable. It is also sometimes called the independent variable because it is independent of the other variable. In regression, the order of the variables is very important.
What is a explanatory variable example?
When a variable isn’t independent for certain
, it’s an explanatory variable. Let’s say you had two variables to explain weight gain: fast food and soda. Although you might think that eating fast food intake and drinking soda are independent of each other, they aren’t really.

What are the types of explanatory variables?

What is an explanatory variable called?
Explanatory Variable. Also known as
the independent or predictor variable
, it explains variations in the response variable; in an experimental study, it is manipulated by the researcher.
Is time an explanatory variable?
Time is
a common independent variable
, as it will not be affeced by any dependent environemental inputs. Time can be treated as a controllable constant against which changes in a system can be measured.
What is the difference between a response variable and explanatory variable?
The difference between explanatory and response variables is
simple
: An explanatory variable is the expected cause, and it explains the results. A response variable is the expected effect, and it responds to other variables.
What are the two response variables?

What is the difference between a response variable and an explanatory variable quizlet?
What is the difference between a response variable and an explanatory variable?
A response variable measures an outcome of a study
. An explanatory variable attempts to explain the observed outcomes.
How do you know if an explanatory variable is significant?
To test the explanatory power of the whole set of explanatory variables, as compared to just using the overall mean of the outcome variable, use
the F-statistic and the p-value printed by SPSS or Excel under “ANOVA
.” If this p-value is less than 0.05, you can reject the null hypothesis (which is that all of the …
Is the explanatory variable The dependent variable?
The value of a dependent variable relies upon that of
an independent variable
. Thus a response variable corresponds to a dependent variable while an explanatory variable corresponds to an independent variable.
What is the explanatory variable in an observational study?
Explanatory variable is
one that may explain or may cause differences in a response variable
(or outcome variable). A treatment is one or a combination of categories of the explanatory variable(s) assigned by the experimenter.
What type of variable is age?
Mondal[1] suggests that age can be viewed as
a discrete variable
because it is commonly expressed as an integer in units of years with no decimal to indicate days and presumably, hours, minutes, and seconds.
What is the response variable in stats?
In statistics, a response variable, also known as a dependent variable, is
a concept, idea, or quantity that someone wants to measure
. It depends on an independent variable. … A response variable might be affected by many different factors, known as explanatory variables.
What is nominal variable?
Categorical or nominal
A categorical variable (sometimes called a nominal variable) is
one that has two or more categories
