Drawing Conclusions

Understanding Results

The overall aim of an experiment is to test a hypothesis and use the data collected to draw a conclusion.
The interpretation of results involves reviewing the data collected and analysing it to decide if it supports or refutes the hypothesis.
Making comparison between results, especially when they are contrasting, is a vital part of drawing conclusions to make a clear judgement.

Use of Statistics

A key part of conclusions relies on the use of statistics. Statistics help to highlight patterns or trends in the data and provide an objective measure to support or refute your hypothesis.
A statistical test may be applied to determine the likelihood that your results are due to chance, and whether a significant difference or correlation exists.
Use of mean, mode, median, range, and standard deviation can give a snapshot of the data distribution. Ensure you understand the use of these statistical measures properly, as misuse can lead to incorrect conclusions.

Making Inferences

An inference is a conclusion or explanation that you develop based on the evidence that you have gathered but isn’t directly observed. It’s an important skill in science, allowing you to deduce possible explanations.
Remember to consider the context of your results, how they relate to the theoretical background, existing research, and real-world applications when making inferences.
Always maintain a sceptical approach and be aware of your assumptions, biases or personal opinions that may creep into the interpretation of results—this can lead to erroneous inferences.

Uncertainty and Error Evaluation

Uncertainty is inherent in all measurements. It’s crucial to mention these uncertainties when drawing conclusions as they affect the reliability of your results.
Look at the errors encountered during the experiment, both random and systematic errors, and discuss their potential impact on your results.
Be cautious in your conclusions; account for limitations and suggest ways that the investigation could be improved or further work that could be done to validate your findings.

Communication of Findings

Once a conclusion has been drawn, it needs to be reported in a clear, concise, and honest manner. This includes providing an overview of the findings, their implications, and any recommendations for future research.
Make sure to use appropriate scientific vocabulary and express your findings in a way that can be understood by others.
Remember that using visuals like tables, graphs or diagrams can often help to clarify and communicate complex information effectively.

Drawing valid conclusions is a vital step in the scientific method. It demands careful reflection on the data collected, accurate use of statistical methods, critical thinking, and above all, intellectual honesty. Clear communication of these conclusions serves to advance understanding and pave the way for further research.
