INTERPRETING DATA
Creating charts and graphs is just the first step. The real value comes from understanding the
information they display and making sense of it. Let’s explore how to interpret data correctly.
Creating charts and graphs is just the start. The real value comes from understanding the data
and drawing conclusions.
Here is how you can interpret the data from the chart:
Check the title: The title tells you what the chart or graph is about.
Look at the labels: The axes show what each side represents (e.g., time, categories).
Observe values and units: Understand the numbers and units (e.g., temperature in degrees).
Study colours or legends: Colours or patterns represent different things in a chart. Check the
legend to understand what they mean.
Identifying Patterns and Trends
A pattern is a sequence that follows a rule and a trend shows how data changes over time.
Recognising these helps you make predictions.
Examples:
If a student’s marks improve every month, that’s a positive trend.
During summer, the temperature usually increases.
Online shopping tends to increase during holidays.
Recognising patterns helps you predict future outcomes, such as predicting a football team’s
performance based on past trends.
Drawing Simple Conclusions
After studying the data, you can draw conclusions to explain what you’ve observed. Conclusions
help you make decisions.
Examples:
If most students score highest in science, you can conclude that science is a strong subject in
the class.
If many students struggle with maths, you can conclude the class may need extra help in that
subject.
A visual pattern rotates a ‘T’ shape 90° clockwise in each step. After 6 steps, what
position is the ‘T’ in?
a) Rotated 90° counter-clockwise b) Rotated 90° clockwise
c) Upside down (180° from start) d) Original position
