Scientific Method Overview

Study Notes

Scientific Method

A systematic approach to understanding the natural world through observation, experimentation, and the formulation and testing of hypotheses.
Key steps typically include observation, question formulation, hypothesis development, prediction, experimentation, data analysis, and conclusion.
Observation involves noting specific details about the world and events.
A well-developed question is specific and focused, prompting research and exploration.
A hypothesis is a potential explanation that is testable.
Predictions are specific statements about the expected outcome of an experiment if the hypothesis is correct.
Experiments are designed to test the predictions, often involving controlled variables to isolate the effect of the independent variable.
Data analysis involves using statistical methods to evaluate results and determine if the observed differences are meaningful or due to chance.
Conclusions drawn from the analysis are interpreted in the context of the original hypothesis, confirming, rejecting, or modifying it based on the evidence.

Scientific Theories

Well-substantiated explanations of some aspect of the natural world that are supported by a large body of evidence from various sources.
Theories are not just guesses; they represent the most robust understanding of phenomena available at a given time.
Scientific theories are constantly being refined and expanded as new evidence emerges.
Theories are distinguished from hypotheses by the fact that they are broader in scope and supported by a large, diverse accumulation of evidence.
Theories can explain a broad range of observations across various facets of a phenomenon; a good theory can explain past observations and be predictive of future ones.

Scientific Laws

Descriptions of fundamental relationships in nature that are consistently observed; they are often expressed as mathematical equations.
Laws are essentially summaries of observed patterns and behaviors.
They do not explain why these patterns occur; rather, they describe what happens.
For example, Newton's Law of Universal Gravitation describes how objects interact gravitationally, but it does not explain why this interaction occurs.
Laws typically arise from a vast body of observations and experimental results demonstrating regularities and specific mathematical relationships.

Scientific Research Methods

A variety of methods and approaches used for systematic investigation of the natural world.
These methods can be broadly categorized into descriptive research (used to observe or describe phenomena), correlational research (used to investigate relationships between variables), and experimental research (used to test cause-and-effect relationships).
Qualitative research often involves in-depth investigation or gathering opinions of people through questionnaires, surveys, observations, or interviews.
Quantitative research employs numerical data and statistical analysis to analyze findings and describe variables involved in a phenomenon.

Ethical Considerations in Scientific Research

Standards of conduct, values, and principles relevant to scientific research to safeguard human participants and maintain integrity.
Procedures for obtaining informed consent, maintaining confidentiality, minimizing risks, and ensuring equitable participation are key elements in research ethics.
Ethical guidelines are designed to maintain integrity, reliability, and public trust in scientific endeavors, taking into account values like fairness, honesty, and responsible reporting of findings.
Conflicts of interest, bias, and plagiarism are important areas of consideration in ethical research practice.
Anonymity and confidentiality of participants are crucial in maintaining integrity, trust, and avoiding biases.
