Learning About Data Handling
Data Collection:
Data collection is the process of gathering information. We can collect data through:
- Surveys - asking people questions
- Observations - watching and recording
- Experiments - testing and measuring
- Research - using existing information
Data Organization:
Once collected, data needs to be organized so we can understand it better:
| Method | Purpose | Example |
|---|---|---|
| Tables | Organize data in rows and columns | Class attendance records |
| Tally Marks | Quick counting method | Voting results |
| Sorting | Arrange data in order | Test scores from highest to lowest |
Data Presentation:
Visual representations help us understand data patterns:
- Pictographs - use pictures or symbols to represent data
- Bar Graphs - use bars to show comparisons
- Pie Charts - show parts of a whole
- Line Graphs - show changes over time
Data Interpretation:
Interpreting data means understanding what the information tells us:
- Identifying the highest and lowest values
- Finding patterns or trends
- Comparing different categories
- Drawing conclusions based on evidence
