Analysing Results, step by step

From raw data to a conclusion.

  1. Tabulate with unitsUnits and uncertainties in the column headings, not in each cell.
  2. Calculate derived quantitiesKeep full precision, and propagate the uncertainties.
  3. Plot and fitExtract the gradient and intercept with their uncertainties.
  4. Compare to predictionDoes the accepted value fall inside your uncertainty range?
  5. Account for any discrepancyName a specific mechanism, not just 'human error'.
  6. Suggest improvementsSay which change would most reduce the dominant uncertainty.

Identify which single measurement contributes the largest percentage uncertainty. That is the one worth improving.

Questions about the Analysing Results poster

What’s on the Analysing Results poster?
6 numbered steps. From raw data to a conclusion. Tabulate with units — Units and uncertainties in the column headings, not in each cell.; Calculate derived quantities — Keep full precision, and propagate the uncertainties.; Plot and fit — Extract the gradient and intercept with their uncertainties.; Compare to prediction — Does the accepted value fall inside your uncertainty range?; Account for any discrepancy — Name a specific mechanism, not just 'human error'.; Suggest improvements — Say which change would most reduce the dominant uncertainty.. Identify which single measurement contributes the largest percentage uncertainty. That is the one worth improving.
Who is the Analysing Results poster for?
Analysing Results belongs to the Physics section rather than to a school year, because physical science is not something one grade owns. Anyone learning methods can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Analysing Results poster?
Compare to prediction, quantify the difference, and account for it. A wall chart earns its place by being glanceable from where the work is happening, so Analysing Results belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
What other posters go with Analysing Results?
Accuracy & Precision, Dimensional Analysis and Designing an Experiment sit alongside Analysing Results in the Physics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Accuracy & PrecisionDimensional AnalysisDesigning an Experiment
Is the Analysing Results poster free to download and print?
Yes. Analysing Results downloads as a free PDF with no account, no email and no watermark, like everything else in the Physics section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Analysing Results poster print at?
Analysing Results is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Analysing Results loses nothing.Printing guide
