Box Plots

Here are some key ideas of box plots you need to know in IGCSE Mathematics curriculum:

Cumulative Frequency Diagrams

In IGCS Mathematics, cumulative frequency: **Adding up** the frequencies as you go along (running total).

The points are always plotted at the **upper class** e.g. if the table says 5 people are between 140-150 cm then you plot the point at 150 cm.

Pi

**Volume**of cylinder:**πr2h**- For calculating the
**surface area**of cylinder, there are two equations in IGCSE Mathematics curriculum:**2πr2 + 2πrh****2πr2 + πdh**(d - diameter)
