Reporting Chemical Data: Statistics, Figures and Data Availability
How results are reported decides whether anyone can build on them. That means stating replicates and uncertainty rather than a single number, drawing figures that show the data instead of hiding it, and depositing the raw files where they can be checked.
What a learner can do afterwards
- Reports a result with the number of replicates and an uncertainty that matches how it was obtained
- Redraws a figure so that the underlying points are visible rather than only their mean
- Explains what selective reporting of successful runs does to a conclusion
- Says which raw files should be deposited for a stated result and in what form

How you report decides whether anyone can build on your work. State the number of replicates with every result, and quote an uncertainty that matches how the number was obtained. Share all the runs, not just the pretty ones, because open data only helps when it is the complete data.
Draw figures that show the data instead of hiding it. Plot the underlying points rather than only their mean, so readers see the spread your summary compresses. Reporting only successful runs warps every conclusion built on the figure.
Open sharing changed what checking means. Papers and raw data files now sit online where anyone can read them free, so others can check calculations, redraw figures, and repeat the experiment. Mistakes get caught faster and good results get confirmed faster when the files are truly reachable.
Deposit the raw files behind each stated result in a usable form: the readings, not just the polished table. Name the file set per result so a stranger can retrace your steps. Each new result then becomes something the next person can truly build on.
Show every run with its uncertainty, plot the points, and deposit the raw files.
