The question does not indicate specific variables to test or measure.

• Testable question

• inference

• untestable question

• hypothesis

A set of tasks that can help answer a question in which there is one variable that can be changed and one that can be measured.

• experiment

• variable

• testable question

• hypothesis

In an experiment, the standard that is used for comparison, it's used to evaluate if an experiment is working.

• experimental design

• variable

• constant

• control

When an experiment is done several times to see if similar results are observed each time.

• qualitative data

• repeated trials

• dependent variable

• constant
