1
Experimental Design Vocabulary
2
It is what you are trying to solve in an experiment.
3
Problem Question
4
a predicted answer to a scientific problem based on observations, previous knowledge, and research.
5
Hypothesis
6
the factor that is changed on purpose by the experimenter; also called the manipulated variable.
7
Independent Variable
8
the way(s) in which the independent variable is changed by the experimenter.
9
Levels of the Independent Variable—
10
factor that responds to the independent variable; the factor you measure or observe as data
11
Dependent Variable
12
an experiment that tests only one variable at a time and is used as a comparison.
13
Controlled Experiment (control)
For example: If the problem is: How does the height of a basketball hoop effect the number of points scored? Then the controlled experiment would be the 10 foot hoop because it is the “normal” height.
14
this is the group being tested for a reaction to a change in the variable; also known as the treatment group.
15
Experimental Group
16
variables in an experiment that are kept the same in all trials ( so they do not affect the results)
17
Constants—
18
the number of times an experiment is tested
the number of times an experiment is tested. The more an experiment is tested, the more reliable the results become.
19
Repeated Trials—
20
The process by which scientists answer questions and solve problems.
