Amber has written the following hypothesis:
"If a rock is put under a great deal of pressure,
then the minerals in the rock will chemically change."
What is the manipulated variable used in an investigation to test this hypothesis?

A variable
A hypothesis is tested in a scientific investigation.
Scientists test hypothesis by setting up an experiment. They choose a independent and a dependent variable and test the experiment.
Was this in the textbook? The answer is a, the X axis

The independent variable in an experiment is the one that is manipulated in order to test a hypothesis. There will also be a control used in order to make sure that the variable is doing what it is supposed to.

By collecting data. Hypotheses are tested through experimentation, which can be manifest in an infinite amount of ways. The common ground in all hypothesis testing is that both a control (a group that is free of experimental manipulation in the studied variable), and an experimental group (a group with one experimental variable manipulated to test the effect of this variable) are needed to understand the question raised in the hypothesis.
