Criteria Feedback
- You identified a focused chemical question with clear variables and an appropriate topic area.
- You showed thoughtful planning by including controls, repeats, and apparatus uncertainties.
- Your method is detailed enough that a reader can mostly follow the intended procedure.
- Several key details are inconsistent across the write-up, including sample volume, iodine concentration, reaction time, and starch concentration.
- The procedure is missing a clearly defined blank, which is necessary for a valid iodine-value investigation.
- Some parts of the method would still be difficult to reproduce exactly because not every step is stated consistently for all five oils.

Criteria Feedback
- You present raw titres, means, processed values, and uncertainty estimates in a way that lets the reader follow your working.
- You attempt appropriate forms of processing for the investigation, including averaging and comparing results across oils.
- Your tables and graph make the data progression reasonably easy to track.
- The processing uses the back-titration result incorrectly, so the iodine values are not calculated from a valid chemical basis.
- There are noticeable calculation errors and inconsistencies, including the standard deviation work and the handling of units.
- The uncertainty treatment is incomplete because important sources of error and the missing blank are not properly incorporated.
