### Data collection
Data should be collected in an organised and titled table that should be prepared before the experiment. To reduce plagiarism, the data table must be verified by a teacher before leaving the lab space. After verification, **no new data** can be added. During an experiment that spans multiple days, this data must be verified every day. The data table must include:
Data should be collected in an organised and titled table that should be prepared before the experiment. The data table must include:
- units with uncertainty, typically in the table header
- *qualitative* data (quantitative data can be optional in some experiments)
- repeated data/controlled variables, typically in the title
- any relevant information should be listed under the title
Only **raw data** prior to any processing or calculations, with the exception of averages, should be present in the data table.
A data table should be as concise as possible, and redundancy should be minimised. In that vein, trial numbers should *not* be recorded unless that data is relevant.

**Effect of Fat Content on Sugar Content in Ice Cream**
**Table 1: Effect of Fat Content on Sugar Content in Ice Cream**
| Fat Content (g ± 0.1 g) | Sugar Content (g ± 0.1 g) | Notes |
| --- | --- | --- |
| 2.0 | 5.1 | - strawberry ice cream |
| 0.1 | 2.3 | - mint chocolate chip ice cream |
Whenever possible, data tables should *not* span multiple pages. If that is unavoidable, a new title with "…continued" and new column headers must be present at the top of each new page.
### Data processing
A single sample calculation showing all steps should be present and clearly explained. The rest of the data can be processed without describing any steps. A **single** graph may be included if needed.

- units and uncertainties must be present in all calculations
- simple operations such as averages and conversions (e.g., g to kg) do not need to be explained
- the graph, if any, should span a full page and should directly answer the research question
- the graph, if any, should span at least half of the page (ideally the full page) and should directly answer the research question
A final, reorganised, and processed data table should be present here, showing only relevant information.

- plot the independent variable on the horizontal axis and the dependent variable on the vertical axis
- label the axes, ensuring that the labels include units
- choose an appropriate scale for each axis
- give the graph an appropriate title
- give the graph an appropriate title at the **bottom** in **title case**
- draw a line of best fit
- include all uncertainties in the form of error bars
- if the error bars are too small to see, it should be noted explanation below
