Sharp Eyes, Sharp Minds: Analysing and Evaluating Your Evidence — Science

Sharp Eyes, Sharp Minds: Analysing and Evaluating Your Evidence

1 of 4

For grown-ups

Companion summary

Have you ever watched a detective piece together clues to solve a mystery — that is exactly what scientists do with data? When doctors test new medicines, they analyse results carefully to decide if the treatment is truly safe and effective. In a famous experiment, scientists once thought they had found faster-than-light particles — careful evaluation revealed a loose cable was the culprit. When you finish your next practical, try asking yourself: what could have gone wrong, and how would you improve it next time?

The Suspicious Result

A student measures how far a paper ball travels when flicked. Her five results are: 42 cm, 39 cm, 41 cm, 78 cm, 40 cm. Something looks very wrong. Can you spot it? Before you read on, write down which result seems strange and why you think it happened. This skill — spotting the odd result out — is one of the most important things a scientist can do.

💭 Think about this

Look at these five results: 42, 39, 41, 78, 40. Which one stands out, and what might have caused it?

From Raw Results to Real Understanding

Once you have collected data in an investigation, the real scientific thinking begins. This stage is called and evaluation. **Analysis: Finding the Pattern** Analysis means looking at your results to find a pattern or . A trend is a general direction your data moves — for example, 'as temperature increases, the rate of reaction increases'. Always use actual numbers when you describe a trend. Instead of saying 'the plant grew more in light', say 'the plant in full light grew 12 cm on average, compared with 4 cm in shade — three times as much'. Some investigations show a directly proportional relationship: when one variable doubles, the other doubles too. Others show an inverse relationship: as one goes up, the other goes down. Naming the type of relationship shows you really understand your data. **Anomalous Results** An anomalous result — sometimes called an outlier — is a data point that does not fit the pattern. In the starter, 78 cm is the anomaly. Anomalies can happen because of human error (flicking too hard by accident), equipment error (ruler moved), or a one-off change in conditions (a gust of wind). You should not simply delete an anomaly; instead, explain it, and consider whether to include it in your calculation. Usually, identified anomalies are left out of the mean so they do not distort the result. **Calculating a Mean** A mean (average) makes your conclusion more reliable. Add all valid results together, then divide by how many there are. If you spot and remove an anomaly, divide only by the remaining values. **: How Trustworthy Is Your Evidence?** Evaluation means judging the quality of your investigation. Ask yourself three questions: 1. Are the results ? Did you get similar values each time you repeated the test? 2. Are they ? Would another person following your method get the same results? 3. Was the method fair? Was only one variable changed at a time? After evaluation, you suggest improvements — ways to make the investigation more accurate or reliable next time. Good improvements are specific: 'Use a digital thermometer instead of a glass one to reduce reading errors' is far better than just 'be more careful'. **Worked Example** A student investigates how the height a ball is dropped from affects the height it bounces. Results (three repeats at each height): | Drop height (cm) | Bounce 1 (cm) | Bounce 2 (cm) | Bounce 3 (cm) | |---|---|---|---| | 20 | 12 | 11 | 13 | | 40 | 23 | 24 | 22 | | 60 | 35 | 36 | 34 | | 80 | 47 | 46 | 62 | Analysis: There is a positive trend — as drop height increases, bounce height increases. At 20 cm drop, mean bounce ≈ 12 cm; at 60 cm drop, mean bounce ≈ 35 cm, roughly proportional. The result of 62 cm at 80 cm drop is anomalous — it is much higher than the others at that height. It may have been caused by the ball landing at a slight angle, giving extra energy to the bounce. Evaluation: The other three sets of results are consistent (within 2 cm of each other), suggesting the method is repeatable. Improvement: use a light gate sensor to measure bounce height electronically, removing human reaction-time error when reading the ruler.

Worked example

Using the ball-drop data above: the anomalous result (62 cm at 80 cm drop) is identified and excluded from the mean. The remaining values (47, 46) give a mean of 46.5 cm. The student then states the trend using numbers, names the anomaly and its likely cause, and suggests using a light gate to improve accuracy.

Try it yourself

Read each question carefully and choose the best answer. Think about the analysis and evaluation skills you have just learned.

1. A student records the following times for a toy car to travel 1 metre: 3.2 s, 3.1 s, 3.3 s, 3.2 s, 7.8 s. Which result is anomalous?

2. After removing the anomalous result of 7.8 s from the set above, what is the mean of the remaining four results (3.2, 3.1, 3.3, 3.2)?

3. A student says: 'As the amount of fertiliser increased, the plant grew taller.' A scientist would say this conclusion is weak. Why?

4. Which of these suggestions is the most useful improvement to a thermometer-reading investigation?

5. A student tests whether exercise affects heart rate. She exercises for 1 minute and measures her own heart rate three times, getting 98, 97, and 99 bpm. Her friend repeats the same method and gets 101, 103, and 100 bpm. What do these results tell you about the investigation?

Lock It In

Always describe a trend using real numbers from your data, not just general words.
Spot anomalies, explain their likely cause, and exclude them from your mean calculation.
Evaluate your method by checking repeatability and reproducibility, then give a specific improvement.

1. A student investigating seed germination gets these germination times in days for six seeds: 4, 5, 4, 5, 4, 19. She calculates a mean of 6.8 days. What should she have done before calculating the mean, and why?

🌱 Reflect

Think about a recent science investigation you have done or observed. Can you identify one result that seemed odd? What might have caused it, and how could the method be improved?
