  2. Experiment

    • A carefully designed procedure carried out to investigate a scientific question or hypothesis.

  3. Control Group

    • In an experiment, the group that is not exposed to the independent variable and used as a basis for comparison.

  4. Variables

    • Factors that can be measured or controlled in an experiment, influencing the outcome.

  5. Data

    • Information, measurements, or observations collected during an experiment.

  6. Results

    • The outcomes or findings of an experiment, presented in a quantitative or qualitative manner.

  7. Analysis

    • The examination of data to identify patterns, trends, or relationships.

  8. Conclusion

    • A summary of the results and the acceptance or rejection of the hypothesis based on evidence.

  9. Theory

    • A well-substantiated explanation of natural phenomena, supported by extensive evidence.

  10. Law

    • A concise statement that describes a fundamental relationship observed in nature, supported by consistent evidence.

  11. Empirical Evidence

    • Data obtained through direct observation or experimentation.

  12. Replication

    • The repetition of an experiment to validate or challenge its results.

  13. Sample Size

    • The number of subjects or data points used in an experiment or study.

  14. Accuracy

    • The degree of closeness between a measured value and the true value.

  15. Precision

    • The degree of consistency or reproducibility of measurements.

  16. Inference

    • A logical conclusion or deduction based on evidence and reasoning.

  17. Causation

    • The relationship between cause and effect, indicating that one event leads to another.

  18. Correlation

    • A relationship between two variables that tend to change together, without implying causation.

  19. Bias

    • Prejudice or favoritism that may affect the objectivity of data collection or analysis.

  20. Peer Review

    • Evaluation of research or scientific work by experts in the same field to ensure quality and validity.

  21. Reproducibility

    • The ability of other researchers to obtain similar results when repeating an experiment.

  22. Independent Variable

    • The variable that is deliberately manipulated in an experiment.

  23. Dependent Variable

    • The variable that is measured or observed and affected by changes in the independent variable.

  24. Null Hypothesis

    • A statement suggesting that there is no significant relationship between variables in an experiment.

  25. Statistical Significance

    • The likelihood that the results of an experiment are not due to chance.

  26. Controlled Variables

    • The factors in an experiment that are intentionally kept constant to prevent them from influencing the results.

  27. Experimental Error

    • The inaccuracies or uncertainties that may arise during the conduct of an experiment.

  28. Validity

    • The extent to which a test, experiment, or study accurately measures what it intends to measure.

  29. Reliability

    • The consistency and stability of the results obtained from an experiment or measurement.

  30. Bias

    • A systematic error in data collection or analysis that results in a deviation from the true value.

  31. Sample Bias

    • A bias that arises when the sample used in a study does not accurately represent the entire population.

  32. Confounding Variable

    • An extraneous factor that may affect the results of an experiment and confuses the interpretation of the data.

  33. Ethics

    • The moral principles and guidelines that govern the conduct of research involving human subjects or animals.

  34. Informed Consent

    • Consent obtained from participants in a study after they have been fully informed about the nature of the research.

  35. Anecdotal Evidence

    • Evidence based on personal accounts or stories, which may not be reliable for drawing scientific conclusions.

  36. Statistical Analysis

    • The process of using statistical methods to analyze data and draw meaningful conclusions.

  37. Randomization

    • The process of assigning participants to different groups in an experiment randomly, reducing bias.

  38. Standard Deviation

    • A measure of the spread or variability of data points from the mean in a data set.

  39. Normal Distribution

    • A symmetrical bell-shaped distribution of data points around the mean, commonly found in nature.

  40. Probability

    • The likelihood of an event or outcome occurring, expressed as a percentage or fraction.

  41. Significance Level

    • The threshold used to determine whether the results of an experiment are statistically significant.

  42. Research Design

    • The overall plan or structure of an experiment or study, including its methodology and data collection procedures.

  43. Peer Review Process

    • The evaluation of research or academic work by experts in the same field before publication.

  44. Systematic Review

    • A comprehensive review of existing literature and research studies on a particular topic.

  45. Literature Review

    • A critical examination and summary of the available literature on a specific research question.
