Check that tables include headings, units, and ordered values. Calculate averages when there are repeats and arrange data chronologically or by category.
Check: Can you view the whole data set at a glance?
Flowchart
Use these steps to interrogate data until the story becomes clear.
1) Organise the data
2) Look for overall trends
Describe how the dependent variable changes as the independent variable increases. Identify whether the relationship is positive, negative, or shows a peak/plateau.
Check: What happens most of the time in this data set?
3) Examine details
Compare groups, calculate the range, and highlight points that don�t match the trend (anomalies). Think about what might have caused them.
Check: Where does the pattern change or break down?
4) Explain the pattern scientifically
Use scientific knowledge to suggest why the pattern occurs. Link evidence to ideas about particles, forces, or biology. Consider whether the data is strong enough to support your claim.
Check: Can you justify the pattern with evidence and science facts?
Explanation
Understanding patterns
Patterns are relationships that appear in data. They help you answer the original question: Does changing one variable affect another? Identifying patterns involves spotting similarities, differences, increases, decreases, and repeating cycles.
Tools for pattern spotting
- Tables: Look along rows and columns to spot increases or decreases.
- Graphs: Use shape and slope of the line to describe trends.
- Range: Highest minus lowest value shows how spread out the data is.
- Averages: Mean, median, or mode smooth out small variations so the pattern is clearer.
Explaining what you see
Once you spot a pattern, use scientific vocabulary to explain it. For example, �Seeds placed in warmer soil germinated faster because higher temperatures speed up chemical reactions inside the seed.� If there is no clear pattern, say so and suggest what data you would need.
Key Vocabulary
- Trend: Overall direction of change.
- Range: Difference between the largest and smallest values.
- Average (mean): Sum of values divided by how many there are.
- Correlation: When two variables change together.
- Anomaly: A result that does not fit the pattern.
Why pattern spotting matters
Scientists rarely look at single measurements. Instead they rely on patterns in data to make predictions, design new inventions, or spot problems. Being able to identify and explain patterns shows that you understand both the data and the science behind it.
Examples
Example 1: Shadow length
Plotting shadow length against time of day shows a U-shaped curve. The pattern tells you that the Sun is highest at midday, giving the shortest shadow.
Example 2: Plant growth with fertiliser
Two groups of plants (with and without fertiliser) are measured weekly. Both grow, but the fertilised group has a higher average. The pattern shows fertiliser speeds growth.
Example 3: Reaction time vs hours of sleep
A scatter graph reveals a negative correlation: more sleep gives shorter reaction times. One point far away from the line may be an anomaly (perhaps the pupil had extra caffeine).
Example 4: Seasonal bird counts
Counts of garden birds show peaks in winter and dips in summer. Spotting this yearly pattern helps conservationists plan feeding programmes.

Common Mistakes
Mistake 1: Describing numbers but not the pattern
� Wrong: �2, 4, 6, 8.�
? Right: �As the force doubled from 2 N to 4 N, the stretch doubled too, showing a proportional relationship.�
Mistake 2: Ignoring range
� Wrong: Comparing two groups using just the mean.
? Right: Mention how spread out the results are to judge reliability.
Mistake 3: Forgetting anomalies
� Wrong: Pretending unusual results never happened.
? Right: Identify anomalies and suggest possible causes.
Mistake 4: Explaining without science
� Wrong: �It just does that.�
? Right: Link patterns to scientific ideas like energy transfer, adaptation, or particle motion.
Summary
- Organise data with headings, units, and averages.
