Study Notes
Hypothesis Based Science Overview
- Hypothesis Based Science consists of five steps that facilitate the creation of valid and testable experiments.
Steps of Hypothesis Based Science
- Observation: Noticing and describing phenomena in the natural world.
- Question: Formulating a question based on observations.
- Hypothesis: Proposing an explanation that answers the research question.
- Prediction: Anticipating the expected outcome of the experiment and the rationale behind it.
- Test: Conducting experiments to validate or falsify the hypothesis.
Research Questions Examples
- How does the internal temperature change in geckos affect their health?
- How likely are pigeons to rely on humans rather than nature for food?
- How is plant growth affected by atmospheric pressure?
- Effective research questions must be both testable and researchable.
Understanding Hypotheses
- A hypothesis is a testable and falsifiable explanation addressing a specific observation.
Variables and Treatments
- Variables: Elements that are measured to assess the validity of a hypothesis.
- Independent Variables: Factors that are manipulated in the experiment.
- Dependent Variables: Outcomes that are measured and observed.
- Standardized Variables: Conditions kept constant to avoid influencing the results.
- Experimental Treatments: Specific manipulations applied to the independent variable.
- Control Treatments: Baseline conditions used to evaluate the effectiveness of experimental treatments.
Types of Data
- Qualitative Data: Data based on sensory observation (sight, smell, etc.).
- Quantitative Data: Data represented by numerical values.
Statistical Tests Usage
- T-test: Used to compare differences between sample groups when normal distribution is unknown.
- Chi-squared Test: Analyzes the closeness of two data sets and assesses the accuracy of predictions.
- P-value: Indicates the probability of results occurring due to random chance.
