# What would happen if we did not control the variables?

## What would happen if we did not control the variables?

A confounding variable can have a hidden effect on your experiment’s outcome. If control variables aren’t kept constant, they could ruin your experiment. If you do not, your experiment compromises internal validity, which is just another way of saying your experimental results will not be valid.

## What is continuous variable in research?

Continuous variables are variables that can take on any value within a range. Continuous variables are also considered metric or quantitative variables, where the variable can have an infinite number or value between two given points. However, height is considered a continuous variable.

## How do you find the independent variable example?

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.

## What is constant variable?

A constant is a data item whose value cannot change during the program’s execution. Thus, as its name implies – the value is constant. A variable is a data item whose value can change during the program’s execution. Thus, as its name implies – the value can vary. Constants are used in two ways.

## How do you find the continuous variable?

Continuous variables can take on almost any numeric value and can be meaningfully divided into smaller increments, including fractional and decimal values. You often measure a continuous variable on a scale. For example, when you measure height, weight, and temperature, you have continuous data.

## Is the type of plant an independent variable?

For the earlier plant experiment, “How Plants Grow In Response to Light,” the growth of the plant is the dependent variable being observed The plant growth is in response to changes in the amount of light the plant receives, is the independent variable.

## What is an independent variable dependent variable and control?

Graphing Your Experiment The independent variable is graphed on the x-axis. The dependent variable, which changes in response to the independent variable, is graphed on the y-axis. Controlled variables are usually not graphed because they should not change.

## How do you tell the difference between independent and dependent variables?

The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause and effect. If the independent variable changes, then the dependent variable is affected.

## Why is time a dependent variable?

In typical studies, time is almost always an independent variable. It is independent because it can, for example, predict or explain changes in the values of the dependent variable(s) being studied.
