DATA REPRESENTATION...PLZ HELP. How do i represent this in a graphical form?

IMG_20160505_031206.jpgHow to put this data into a suitable graphical form. Any help plz???? A bar chart appropriate? How should be the scalingg??? (EDEXCEL AS BIOLOGY UNIT 3 2009 june paper-Q2 (b)(ii) : REFERENCE)
I would go for a bar chart, increasing by 5000 each time, or even a log scale since the difference between the smallest and largest values are quite wide and therefore would be hard to see on a standard graph. You could also combine a bar with a line chart (have a dot in the centre of each horizontal bar, and draw a curve).

Thanks fro helping me out. But with 5000 increasing, i dont seem to get the max value within the graph space provided in exam sheet. What is that other thing you said 'log scale'. I didnt understand. Can you help further please. The space for graph is attached:IMG_20160506_211525.jpg

Sorry for how crude the graph is: it's not accurate at all because I did it on plain paper! It looks like they want a line graph. A log graph is basically following a logarithmic scale, i.e. instead of numbering it:
Linear (normal): 2000, 4000, 6000, 8000, 10,000, 12,000, 14,000 etc
it can be numbered
Logarithmic: 2000, 4000, 6000, 8000, 10,000, 20,000, 40,000, 60,000, 80,000, 100,000.

In other words, log scales let you skip up from small numbers to high numbers to give a more linear graph. Also notice that I've put a little squiggle on the y axis. This indicates that I've missed 0 - 1000 because there are no values below 1000 in the table :smile: Also note that the y axis reads "log(number of tests)".

That's my graph. Hope this helps and I'll reply quicker now if you have any other questions!
