Biology Quiz - Unit 4 - Draw a Conclusion (Questions)

This GCSE Biology quiz helps you practise drawing clear conclusions from results, spotting trends in data, and explaining what your experiments really show.

(quiz starts below)

Fascinating Fact:

When drawing a conclusion, you should describe any clear trends, for example whether one variable increases as another increases. This makes your reasoning explicit.

In GCSE Biology, you are expected to do more than just collect results. You must spot patterns in the data, describe any trends, and then explain them using scientific ideas about the variables you investigated.

Key Terms

  • Conclusion: A clear statement that explains what your results show about the relationship between variables.
  • Trend: A pattern in the data, such as results increasing, decreasing, or staying constant.
  • Evidence: The specific data values or ranges you quote to support your conclusion.

Frequently Asked Questions (click to see answers)

How do you draw a conclusion from results in GCSE Biology?

To draw a conclusion, first describe any clear trend in the data, then link it to the independent and dependent variables, and finally support your statement with specific numbers from your results table.

What should a good Biology conclusion include in an exam answer?

A good conclusion includes the main trend, at least one piece of numerical evidence, a link back to the hypothesis or question, and a short scientific explanation for why the pattern occurs.

How is drawing a conclusion different from evaluating an experiment?

Drawing a conclusion explains what the results show, while evaluating an experiment comments on how good the method was, how reliable the data are, and how the investigation could be improved.

Biology Quiz - Unit 4 - Draw a Conclusion (Answers)
1. A conclusion is...
[ ] based on the design of the experiment
[x] a summing up of what the results show
[ ] the hypothesis
[ ] a statistical test
It should be linked to the original aim of the experimental work
2. Conclusions are based on which of the following?
[ ] Hypothesis
[ ] Mean
[ ] Range
[x] Results
Conclusions are always based on the results of the experiment
3. We refer to this in the conclusion, and state whether the results agree.
[ ] Objective
[x] Prediction
[ ] Data
[ ] Mean
Making predictions and then testing them to see if they are correct is called the scientific method. It works very well outside of science and can help you to avoid jumping to the wrong conclusion in many different situations in your life!
4. What is the conclusion for the following data?

Temperature/degrees Celsius           Volume of gas/cm3

                    20                                                   5

                    30                                                   12

                    40                                                   26
[ ] As the temperature increased, the volume of gas decreased
[ ] As the volume of gas increased the temperature decreased
[ ] As the temperature increased, the volume of gas remained the same
[x] As the temperature increased, the volume of gas increased
Always relate the two variables in the conclusion
5. Conclusions are positioned...
[ ] at the start of the report
[ ] in the results table
[x] at the end of the report
[ ] within the method
It is the logical place as a conclusion sums up what you have discovered from your investigation
6. Which of the following is the correct order for writing up an experiment?
[x] Prediction - method - results - conclusion
[ ] Conclusion - method - results - prediction
[ ] Results - prediction - method - conclusion
[ ] Prediction - method - conclusion - results
Prediction first, conclusion last
7. If the results double every time the key variable is doubled, the conclusion will say the results are in...
[x] direct proportion
[ ] indirect proportion
[ ] inconclusive
[ ] unusual
In investigations that have generated a set of figures in the results, always try to put a number on any correlation. It is not always obvious or possible though, so don't worry too much if you can't do this
8. Results which disagree with the prediction are described as...
[ ] anomalous
[ ] outliers
[x] not supporting the prediction
[ ] supporting the prediction
Always include a statement in the conclusion about whether the results support the prediction or not
9. If results do not support the prediction, it means that...
[ ] the prediction was correct
[x] the prediction could have been wrong
[ ] we rushed the experiment and must repeat it
[ ] we need to do more research
As well as this, there could have been errors in the experiment that generated incorrect or inconclusive results (results that neither agree or disagree with the prediction). Investigations with a conclusion like this are great for suggesting ideas for further work which will help you to gain good marks, even if your investigation did not go as hoped. It is an opportunity, not a disaster!
10. What is the conclusion for the following data?

Height/mm           Mass/g

      15                        26

      20                        6

      25                        31
[ ] As the height increased, the mass increased
[ ] As the height increased, the mass decreased
[ ] As the height decreased, the mass decreased
[x] No trend in the data, inconclusive
