Short-Question

# Is food dependent or independent variable?

## Is food dependent or independent variable?

The amount of food depends on the day, so it is the dependent variable.

What are some examples of independent dependent and controlled variables?

Example: a car going down different surfaces. Independent variable: the surface of the slope rug, bubble wrap and wood. Dependent variable: the time it takes for the car to go down the slope. Controlled variable: the height of the slope, the car, the unit of time e.g. minutes and the length of the slope.

### What are your independent dependent and constant variable?

A controlled variable is one that is constant and is unchanged in an experiment. It is held constant in order to observe the result of the independent variable. An independent variable is the variable that is being changed in the experiment in each trial, while a dependent variable is the one that is being measured.

What are controlled variables give an example?

Examples of Controlled Variables Temperature is a common type of controlled variable. If a temperature is held constant during an experiment, it is controlled. Other examples of controlled variables could be an amount of light, using the same type of glassware, constant humidity, or duration of an experiment.

#### Is a dependent variable a constant?

A constant is an unchanging quantity. In any experiment, the value of one quantity must be systematically changed in order to measure its effect on another quantity. The quantity whose value changes in response to the change of independent variable value is called the dependent variable.

Is constant and control the same thing?

Differences between Constant and Control A constant variable does not change. A control variable on the other hand changes, but is intentionally kept constant throughout the experiment so as to show the relationship between dependent and independent variables.

## What are examples of constant variables?

TL;DR: In a science experiment, the controlled or constant variable is a variable that does not change. For example, in an experiment to test the effect of different lights on plants, other factors that affect plant growth and health, such as soil quality and watering, would need to remain constant.

Which is an independent variable and which is a controlled variable?

Here the independent variable is the amount of light and the moth’s reaction is the dependent variable. A change in the independent variable i.e. amount of light directly causes a change in the dependent variable i.e. moth behaviour. A controlled variable is one which the scientist holds constant (controls) during an experiment.

### When does the dependent variable change what happens?

The dependent variable changes as a result of the changes made to the independent variable. In summary, the independent variable is what the researcher changes, and the dependent variable is what changes because of the alteration to the independent variable.

Why is it important to keep control variable constant?

It’s important for a scientist to try to hold all the variables constant except for the independent variable. If a control variable changes during the experiment, it may invalidate the correlation between the dependent and independent variables.

#### Which is an independent variable in a nutrition experiment?

Researchers in the field of nutrition might measure variables such as lab values, weights, effects of a medication, athletic performance, and so on. There are two key variables in every experiment: The independent variableis what the researcher changes or the variable that changes on its own, such as age or time.
