Treatment of information collected...
6 marks available - a lot of these marks are for actions and not words!
Suggested word count of 500 out of the 2500 words. *However, you may not use many words in this section and so can carry them over to Step 4.
Deadline First Draft: Wednesday 14th October (**For Step 3 & 4**).

The presentation of your data (graphs etc) and the written analysis must be integrated - no random graphs on a single page.
You should treat and display the data collected using the most appropriate techniques.
The "most appropriate techniques" are:
- the most effective
- well used
- good quality presentation
The presentation of results could involve processes such as:
- Cross sectional diagrams and graphs
- Graphs to show bed load size
- Scatter graphs to show the relationship between wetted perimeter and velocity
- Scatter graphs to show how discharge changes with the distance from the source
- Annotated diagrams/photographs of each site, including the human activity
- Sketch of the long profile of the river
You should consider including a statistical test that includes confidence limits. A member of the Maths department or a willing IB DP Maths students will lead a session explaining this. A suggested use of a statistical test would be to quantify the strength of relationship distance from source and one of the sets of data you collected. Here is a worked example.
You will need to work out the river velocity from the data you have collected. Here is the calculation
Discharge (m3/s) = Cross sectional area (m2) × Velocity (m/s)
Cross sectional area (m2) = Width (m) × Mean depth (m)
Make sure you do the following...
- Use the most appropriate methods - just using Excel or Google Sheets to produce graphs may not be the most appropriate method!
- Include a statistical test.
- All the axis are correctly and clearly labeled.
