In a controlled experiment, there is only one factor that can change at a time. This tested factor that might affect the outcome of the experiment is called this.
What is the independent variable?
100

What is " experiment " ?
100
The "numbers" part of a scientific measurement.
What is the "nominal value" ?

A pie chart is most appropriate for showing this type of relationship.
What is the proportion of the parts to the whole?
100
The symbol for the base unit "liters."
What is capital "L" ?
200
A second factor measured by scientists in an experiment, this factor results from changes to the independent variable.
What is the dependent variable?
200
The very first step of the scientific method (a direct method of gathering information in an orderly way).
What is " observation " ?
200
The approximate mass of a human heart.
What is one kilogram?

This type of representation is used to see if there is a correlation.
What is a scatter plot?
200
M

This is the group in an experiment exposed to the factor being tested.
What is the experimental group?

What is " Gs " ?
400
In an experiment, this group is used for comparison.
What is the control group?
400
The type of observation made in nature just to see what an organism is doing without it knowing it is being observed.
What is a " naturalistic observation " ?
400
The type of instrument scale which shows a continuously variable quantity such as length or time, requiring the user to infer the measurement nominal value and uncertainty.
What is an analog scale?
400
This type of representation is most appropriate for showing grouped data.
What is a bar chart?
400
The symbol for the prefix that means "one billionth" of any base unit.
What is " n " ? (name = nano)

In an experiment, these are factors that remain fixed while the independent and dependent variables change.
What are the controlled variables?
500
