## What are 3 controlled variables?

Controlled variable: the height of the slope, the car, the unit of time e.g. minutes and the length of the slope. What you can decide to change in an experiment. What you observe or measure Things you keep the same –do not change.

### How many variables should be changed in a controlled?

one variable

A controlled experiment works with one variable at a time. If several variables were changed at the same time, the scientist would not know which variable was responsible for the observed results. 3. In a “controlled experiment” only one variable is changed at a time.

**What are the variables in a controlled experiment?**

In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled.

**What is a controlled variable example?**

Examples of Controlled Variables Temperature is a much common type of controlled variable. Because if the temperature is held constant during an experiment, it is controlled. Some other examples of controlled variables could be the amount of light or constant humidity or duration of an experiment etc.

## What can you do with a function Grapher?

In the functions you can refer to up to four independent variables that are controlled by sliders. The function grapher can plot sinusoidal and other trigonometric functions including sine (sin), cosine(cos) and tan. Similar to a graphing calculator.

### How to enter a formula in a Grapher?

In the functions you can refer to up to four independent variables that are controlled by sliders. This allows you to easily see the effect of changes since the graphs change in real time as you drag the sliders. Enter a formula into one of the three input boxes (f(x), g(x), or h(x)), then press GRAPHor the keyboard Enterkey.

**How to get all four quantitative variables in a chart?**

To get all four quantitative variables in a chart, you need to do a scatter plot matrix that is simply a collection of bivariate scatter plots. There are a few different ways to do this: R’s default pairs () function, pairs () with a custom function, or the

**How many functions can you plot in GFE?**

GFE is a free online function graphing tool that allows you to plot up to three functions on the same set of axes. In the functions you can refer to up to four independent variables that are controlled by sliders.
