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.
