Data Handling notes: key concepts (Class 8 Mathematics)
This chapter covers organising and representing data through grouped frequency tables, histograms and pie charts, and introduces basic probability.
- Organising data
- Raw data is grouped into class intervals with frequencies to make it easier to interpret.
- Histogram
- A bar graph for grouped continuous data with no gaps between bars; the bar height shows frequency.
- Pie chart
- A circle divided into sectors; each sector's angle is proportional to its share of the total (out of 360°).
- Probability
- The chance of an event = (number of favourable outcomes)/(total number of outcomes); lies between 0 and 1.
- Random experiment
- An experiment whose outcome cannot be predicted with certainty, e.g. tossing a coin or rolling a die.
