ata ollection and rocessing Data Collection and Processing Aspect 1 Data table must have for each quantity: NameName SymbolSymbol UnitsUnits Estimated raw uncertainty to 1 SFEstimated raw uncertainty to 1 SF Consistent SFsConsistent SFs Aspect 2 Show one sample calculation of average Calculate uncertainty in average using range/2 to 1 SF Show other calculations or uncertainties EvidenceScore Complete2 Partial1 None at all 0

ata ollection and rocessing Data Collection and Processing NOTE: If no processing of raw data is required then Aspect 2 consists of graphing, best line fit, slope. Aspect 3 Graph data as scatter plot Label axes with name, symbol, and units Best fit trend line - usually linear Uncertainty bars - most uncertain variable Graph min and max slopes to find slope uncertainty EvidenceScore Complete2 Partial1 None at all 0

onclusion and valuation Conclusion and Evaluation Aspect 1 A relationship (linear, proportional, inverse, none) between variables Physical meaning of intercept(s) Systematic error (if any) Aspect 2 Identify at least 2 weaknesses based on uncertainties and errors Aspect 3 For each weakness identify a realistic way to reduce.
