Graph

1. Scale should be (75% of graph / Friendly )
2. Line / Curve of best fit should ( Pass through as many points as possible / Have equal number of points above and below the line / Not have any point too far from line )
3. Graph title should ( Be included / Not be included )

Answers from Mr Alex Lee:
1. Be present
2. One
3. Question number
4. Depending on question - read and answer accordingly

1. 75% of graph, but use convenient intervals - ie multiples of 1, 2 and 5. If very desperate, may use multiples of 4 or 8. Please note the difference between 'intervals' and 'multiples' - 7, 12, 17, 27 may have nice intervals of 5 but are not nice multiples of 5 and hence not appropriate.
2. Chemistry graphs are mainly curves and must pass through as many points as possible - that is the top priority. Secondary priority is equal number of points above and below.
3. Graph title should be included. For all sciences you will not be penalised if you include it, so why not just be kiasu and include?
