Scientific Method Flashcards
1
Q
Hypothesis
A
The most logical explanation for what you just observed.
2
Q
Steps of the Scientific Method
A
Observation, hypothesis formation and logical interpretation, hypothesis testing, and data analysis and interpretation.
3
Q
Variables
A
- Dependent
- Independent
- Experimental
- Control
4
Q
Dependent Variable
A
- The variable that is typically the recorded data that is dependent on the independent variables.
- Will never be the experimental variable.
5
Q
Independent Variable
A
- The variable that which the scientists are changing or controlling.
Almost always the experimental variable - If “time” is involved, time becomes the experimental variable.
6
Q
Experimental Variable
A
- Almost always the independent variable
- If “time” is involved, time becomes the experimental variable.
7
Q
Control Variable
A
- The variable that should remain constant.
- Also known as “constant variables.”
8
Q
Groups
A
- Experimental
- Control
9
Q
Control Groups
A
- Positive Control
- Negative Control
10
Q
Experimental Group
A
-The group of the test subjects that receives the variable beings examined by the hypothesis.
11
Q
Negative Control
A
- The group of the test subjects that should give a negative response with respect to the hypothesis.
- Also known as the “Placebo” Group.
12
Q
Positive Control
A
-The group of the test subjects that should give a positive result with respect to the hypothesis.
13
Q
Presentation of Variables: Graphing
A
- Present “cause and effect”
- The independent variable is displayed on the x-axis.
- The dependent variable is displayed on the y-axis.
- Need titles and units
