# Quick Answer: Can Age Be An Independent Variable?

## How do you manipulate independent variables?

Again, to manipulate an independent variable means to change its level systematically so that different groups of participants are exposed to different levels of that variable, or the same group of participants is exposed to different levels at different times..

## How many independent variables should an investigation have?

one independent variableYou should generally have one independent variable in an experiment. This is because it is the variable you are changing in order to observe the effects it has on the other variables.

## Can gender be an independent variable?

However, gender cannot be imposed or changed by investigators, so it is always an attribute independent variable, when men and women are compared in the study (i.e., when it is an independent variable). . Since the levels of the variable are two distinct categories, it is a nominal variable.

## When can a variable be considered independent and dependent?

An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment. The dependent variable is ‘dependent’ on the independent variable.

## Is height an independent variable?

In this study, time is the independent variable and height is the dependent variable. Answer 5: When you make a graph of something, the independent variable is on the X-axis, the horizontal line, and the dependent variable is on the Y-axis, the vertical line.

## How do you identify an independent variable?

Answer: An independent variable is exactly what it sounds like. 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.

## What are the 3 types of variables?

An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.

## What is dependent and independent variable in Research example?

Here are some other examples of dependent and independent variables in scientific experiments: A scientist studies the impact of a drug on cancer. The independent variables are the administration of the drug – the dosage and the timing. The dependent variable is the impact the drug has on cancer.

## What is an example of an independent variable?

Two examples of common independent variables are age and time. … They’re independent of everything else. The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. It’s what changes as a result of the changes to the independent variable.

## Can you have two independent variables?

There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.

## What are the levels of an independent variable?

If an experiment compares an experimental treatment with a control treatment, then the independent variable (type of treatment) has two levels: experimental and control. If an experiment were comparing five types of diets, then the independent variable (type of diet) would have 5 levels.
