Median, IQR and boxplots

In this clip I show how to find the median and the interquartile rage of these numbers:

2   8   7   4   0   1   1   11   2   3   2




In this clip I show how to draw a box and whisker diagram (or boxplot) using the same data as above.

Percentages, decimals and fractions

Here are a few links to some percentage resources:

This activity is a series of short, simple demonstrations to show how pupils can work out percentages of money by using different strategies

Skillswise - here are some worksheets on fractions, decimals and percentages.

• The percentages section has a quiz - try it by clicking here.
• Here is a decimals quiz

Graph plotting

This YouTube shows how to plot the graph of a linear equation (= straight line).

Have a go at plotting the line before watching the video
1. (a) Plot the graph y = 2x + 1
(b) Use your graph to find y when x = 2.5
(c) From the graph find the value of x when y = 4.

A ditty to recall averages

Hey diddle diddle the median's the middle
You add then divide for the mean
The mode is the one you see the most
The range is the one in between!
