Study Notes
Experimental Design Vocabulary
-
Independent Variable (IV)
- The factor manipulated by the experimenter to assess its influence on dependent variables.
- Considered the "cause," as it leads to changes in dependent variables.
-
Levels of Independent Variables
- Represent the distinct conditions within an experiment (e.g., Experimental vs. Control).
- If an experiment has two conditions, the independent variable has two levels.
-
Dependent Variable (DV)
- Variable that responds to changes in the independent variable.
- Measured and recorded data that reflects the effect of the independent variable.
-
Controlled / Constant Variables
- Elements that remain unchanged during the experiment to ensure valid comparisons.
- Not classified as independent or dependent variables; serve to isolate the effect of IV on DV.
-
Testable Question
- A question framed to be answered through empirical experimentation.
-
Hypothesis
- A testable prediction expressed in an "If...then...because..." format.
- Serves as an initial proposed explanation based on limited observations for further research.
-
Control Group
- The group that does not receive the experimental treatment, serving as a baseline comparison.
- One level of the independent variable, providing a standard for evaluating experimental effects.
-
Test Group(s)
- The group(s) exposed to the experimental treatment to observe effects.
- Compared to the control group to analyze the impact of independent variable manipulation.
-
Experimental Group(s)
- Combination of both control group and test group(s) in a study.
-
Data
- Collected observations during the experimental process, used for analysis.
-
Experimental Conclusions
- Interpretations and explanations derived from the data, addressing whether the hypothesis is supported or rejected.
-
WITEOBOB
- Acronym representing "What is the effect of Blank-On-Blank?" used to clarify the relationship between variables in the experiment.
-
Advantage of WITEBOB
- Aids in identifying both the independent and dependent variables for clarity in experimentation.
-
Multiple Trials
- Repetitions of the same experiment to verify results and enhance reliability.
