ruby92:
How would you draw a frequency histogram, eg m/j 2007 q1(a)?

Sue T:
the heights of the bars should represent th frequency and th widths should all be the same - the bars are stuck 2 each other - google 'the difference between histograms and bar charts' and you'll get a good idea of wat they represent - ive attached th graph you asked about (havent done it all but ive set th scales and started it ;) )
