Evidence to support conclusions/claims made

Collecting Evidence to Support Conclusions

  • Scientific claims or conclusions are based on evidence, which usually takes the form of empirical data collected through observations or experiments.
  • In human biology, such evidence could be biochemical data (e.g., levels of certain molecules in the blood), genetic data, or physical data (e.g., blood pressure).
  • The use of controls (conditions that remain constant) and variable factors (conditions that change) are essential in experiments to ensure any observed differences are due to the variable being tested.
  • Measurement tools must be reliable and valid to ensure data collected accurately represents what is being measured.

Analysing Evidence to Support Conclusions

  • Data should be analysed using appropriate statistical tests to discern significant differences or correlations.
  • Significance is usually indicated by a p-value; a p-value of less than 0.05 is generally considered significant in scientific research.
  • Graphs and tables are useful for visualising data and identifying trends, patterns, or anomalies.
  • Different types of graphs are used for different types of data, e.g., bar graphs for categorical data and scatter plots for continuous data.

Evaluating Evidence to Support Conclusions

  • Reliability of evidence refers to the consistency of the results when the experiment is repeated under the same conditions.
  • Validity refers to whether the experiment accurately measures what it is intended to measure.
  • Bias in experimental design, data collection, or interpretation of results can distort findings; it is important to recognise potential sources of bias.
  • Authors of scientific research should also note limiting factors and suggest how they might impact their conclusions.

Communicating Evidence to Support Conclusions

  • Conclusions are usually communicated in a research paper, which includes an Abstract, Introduction, Methods, Results, Discussion, and References.
  • The Methods section should detail how the research was conducted to allow for replication.
  • The Results section presents the data and findings.
  • The Discussion and Conclusion sections interpret the results in the broader context of what is already known about the topic.
  • Competent communicate of your findings is not just about conveying what you found, but also conveying the significance and implications of these findings.
