Study Notes
Scientific Observations Definitions
- Qualitative Observation: Focuses on characteristics that cannot be quantified and often includes descriptors like color, texture, or smell.
- Scientific Observation: Involves systematically watching and recording behavior to test hypotheses in various settings, ensuring objectivity.
- Quantitative Observation: Involves measurements that can be expressed numerically, often used for statistical analysis.
Basic Research Concepts
- Procedure: A set sequence of steps designed to achieve a specific task or outcome in an experiment.
- Data: Aggregated facts and figures collected for the purpose of analysis, serving as crucial evidence in research.
Graphical Representations of Data
- Line Graph: Utilizes line segments to portray changes over time, effectively demonstrating trends.
- Bar Graph: Employs vertical or horizontal bars to represent and compare data across different categories.
- Circle Graph (Pie Chart): Visually displays data as a whole (100%) divided into proportional segments, illustrating relative sizes of parts to the whole.
Observational Inferences and Predictions
- Inferences: Interpretative conclusions drawn from facts, not directly observable, that provide deeper understanding of data.
- Predictions: Forecasts regarding future occurrences based on historical evidence or observed trends.
Hypothesis and Variables
- Hypothesis: A scientifically testable statement or prediction that stems from a theory, guiding research direction.
- Independent Variable: The specific factor that is deliberately altered to observe its effect on another variable.
- Dependent Variable: The factor that is measured and observed in response to changes in the independent variable.
Control in Experiments
- Control: A baseline experiment conducted without manipulation, used to validate that observed changes are solely due to the tested variable.
