Question 1
You find thatstatistical uncertainty is your largest measurement uncertainty andthat the IV value is your largest propagated uncertainty. How canyou try to improve both uncertainties in the simplest, but mosteffective way?
Choose fromthese answers
start over to collectthe same number of DV measurements as before, but at a greatervariety of IV data points than before
take more measurementsfor the DV values at the IV data points already measured
collect DV data fornew IV data pointsÂ Â
take more measurementsfor the DV value at the IV data points already collected and addmore IV data points
use a new DVinstrument to take moreÂ Â DV measurements fortheÂ Â IVdata points already collected and collectadditional DV data for more IV data points not previouslymeasured
use a new IVinstrument but the same DV instrument to collect the same number ofmeasurements at a wider variety of IV data points
use a new IVinstrument but the same DV instrument to collect more DVmeasurements than before at the same IV data points

All the options mentioned above have relative effectiveness when compared to one another Option 1 Start over to collect the same number of DV measurements as before but at a greater variety of IV data points than before is not likely to reduce the statistical uncertainties or the measurement and adding greater variety of data would likely increase the statistical uncertainty so this is not an effective option Option 2 Take more measurements for the DV values at the IV data points already measured is a viable option because when the number of observation or the See Answer
