Independent variables included in the first step are demographic variables such as age, gender, marital status, and education, and in the next steps are eco- nomic related variables including employment status and self-rated economic condition.
Is age independent or dependent variable?
It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren’t going to change a person’s age.
Can age be used as independent variable?
An independent variable is used in statistics to predict or explain a dependent variable. For example, Age and Gender might be used as independent variables to predict the age of death or life expectancy (dependent variables).
What type of variable is age in an experiment?
Independent variables
An independent variable is a singular characteristic that the other variables in your experiment cannot change. Age is an example of an independent variable.
What are some examples of independent and dependent variables?
The type of soda – diet or regular – is the independent variable. The level of blood sugar that you measure is the dependent variable – it changes depending on the type of soda.
Is gender dependent or independent?
Independent variables included in the first step are demographic variables such as age, gender, marital status, and education, and in the next steps are eco- nomic related variables including employment status and self-rated economic condition.
What type of variable is gender?
A nominal variable has no intrinsic ordering to its categories. For example, gender is a categorical variable having two categories (male and female) with no intrinsic ordering to the categories.
Is gender a measured variable?
A variable measured on a “nominal” scale is a variable that does not really have any evaluative distinction. One value is really not any greater than another. A good example of a nominal variable is sex (or gender).
Can age be an explanatory variable?
The type of therapy given is the explanatory variable; it may or may not affect the response variable. In this example, we have only one explanatory variable: type of treatment. In real life you would have several more explanatory variables, including: age, health, weight and other lifestyle factors.
What type of data is age?
Age can be both nominal and ordinal data depending on the question types. I.e “How old are you” is used to collect nominal data while “Are you the firstborn or What position are you in your family” is used to collect ordinal data. Age becomes ordinal data when there’s some sort of order to it.
What are the independent and dependent variables in this experiment?
In a well-designed experimental study, the independent variable is the only important difference between the experimental (e.g. treatment) and control (e.g. placebo) groups. The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable.
Is gender a discrete variable?
In a well-designed experimental study, the independent variable is the only important difference between the experimental (e.g. treatment) and control (e.g. placebo) groups. The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable.
How do you know if a variable is independent?
You can tell if two random variables are independent by looking at their individual probabilities. If those probabilities don’t change when the events meet, then those variables are independent. Another way of saying this is that if the two variables are correlated, then they are not independent.
What are examples of independent?
The definition of independent is someone or something that is free from the influence or control of another. An example of independent is someone who lives on their own and supports themself. Not dependent; not contingent or depending on something else; free.
What is an example of a independent variable in science?
Either the scientist has to change the independent variable herself or it changes on its own; nothing else in the experiment affects or changes it. Two examples of common independent variables are age and time. There’s nothing you or anything else can do to speed up or slow down time or increase or decrease age.
