Charles Reid Marsh Feb 06 2016 EXPERIMENT 1 Penny Pinching: Statistical Treatment of Data and Analysis of Variance Objective : Effectively understanding and applying statistical methods of distribution and variance within a frame of trials quantifying penny weights relative to dates in order to fathom the margin of uncertainty and accrued error for further extrapolation. By using these tests we will find which set of years there was an increase in mass due to surface oxidation on the pennies and alloy composition change. Data : Tabular (Table 1) Time ; Year Mass ; Grams 1959 3.0772 1976 3.0907
