Study Notes
Experimentation
- Experimental Variable: An aspect that changes during the course of the experiment.
- Control (of an experiment): The variable or part of the experiment used for comparison with all other variables.
- Blind Experiments: Information about the test is withheld from participants to minimize bias.
- Double-Blind Experiments: Neither the experimenters nor the participants know the identities of the experimental setup.
Data Collection
- Subjective: Data based on personal opinions.
- Objective: Measurable data that is not based on personal feelings or preferences.
Data Representation
- Bar Graph: Useful for comparing items or demonstrating relationships between groups. Shows changes overtime and emphasizes significant differences in data.
- Double Bar Graph: Compares the relative sizes of two sets of data.
- Legend: Provides information to understand a graph. Identifies different sets of data.
- Circle Graph/Pie Chart: Represents data by dividing a circle into portions, revealing the size of parts compared to the whole.
- Line Graphs: Record individual data points, enabling identification of changes from point to point.
- X-axis: The horizontal line represents the independent variable.
- Y-axis: The vertical line represents the dependent variable.
