Questions and Answers

What is a hypothesis in the context of scientific investigation?

  • A random guess without any reasoning.
  • A collection of observations and results.
  • An educated guess that tries to answer a question. (correct)
  • A definitive conclusion reached after testing.

    • Which type of data consists of numerical values such as height and weight?

  • Qualitative data
  • Subjective data
  • Statistical data
  • Quantitative data (correct)

    • What is the purpose of vetting the data in an investigation?

  • To determine the relevance of data to a claim. (correct)
  • To compare data between different studies.
  • To present findings to the public.
  • To collect as much data as possible.

    Study Notes

    Glossary

    • Hypothesis: An educated guess to answer a question (what you think might be true).
    • Data: Information gathered during an investigation.
    • Quantitative data: Data expressed using numbers (e.g., minutes, height, weight).
    • Qualitative data: Data described using words or phrases (e.g., passed, failed).
    • Vetting the data: Checking if the data is relevant to the claim made in the investigation.

    IDEA

    • Identify the question.
    • Determine the methods.
    • Establish the results.
    • Assess the conclusion.

    Checking the Conclusion

    • Unsupported claims: Does the conclusion rely on claims not supported by the results?
    • Focus on all results: Does the conclusion focus on all results or just a few?
    • Misinterpretation: Does the conclusion misinterpret the results?
    • Minor detail focus: Does the conclusion focus on minor details while neglecting major details?

    Elements of Experimental Design

    • Variable: A factor that can change.
    • Unexpected variable: A change introduced unexpectedly.
    • Dependent variable: The factor expected to change.
    • Experimental group: The group of interest.
    • Control group: The group that remains unchanged, used for comparison.

    Verifying Accuracy in Scientific Investigations

    • Repeatable, reliable, and consistent: Investigations must be repeatable and consistent.
    • Scientific consensus: Agreement among scientists on an answer.
    • Systematic error: Errors that affect the accuracy of measurement.

    Accuracy and Precision

    • Equipment issue: Problem with equipment causing consistent but wrong results.
    • Random error: Errors affecting measurement precision..
    • Inconsistent results: Inconsistent trials need more data to average out.

    Designing and Modifying an Experiment

    • Ask scientific question.
    • Present hypothesis.
    • Identify variables.
    • Establish groups.
    • Collect data.
    • Compare groups.
    • Draw conclusion.
