Simplifies complex data: It turns difficult numbers into simple, easy-to-understand
information.
Analyses big data: It helps you explore large datasets and find important insights.
Identifies areas for improvement: It highlights areas that need attention, like students needing
extra help in a subject.
Shows relationships: It helps you understand how different pieces of data are connected.
Discovers hidden patterns: It allows you to spot trends that might not be obvious from just
looking at raw data.
Different Ways to Visualise Data
Data visualisation is a way to present data using charts and graphs. These visuals help you
understand data better by making it easier to spot trends and patterns. Let’s explore some
common types of data visualisation:
Bar chart: Uses bars to represent data. The height or length of the bar shows the value.
Example: Showing student marks in different subjects.
Bar charts help you:
Compare values easily.
Identify the highest and lowest values.
Differentiate between categories quickly.
Line graph: Connects data points with a line to show changes over time.
Example: Tracking the temperature for a month.
Line graphs help you:
Show changes over time.
Spot trends (e.g., rising or falling temperature).
Understand fluctuations in data.
