You find that instrumental uncertainty is your largest measurement uncertainty and that the IV value is your largest propagated uncertainty. How can you try to improve both uncertainties in the simplest, but most effective way? a. use a new IV instrument and a new DV instrument to collect more measurements at a wider variety of IV data points
b. collect the same amount of DV data for new IV data points
c. take more measurements for the DV values at the IV data points already measured
d. take more measurements for the DV value at the IV data points already collected and add more IV data points
e. use a new IV instrument but the same DV instrument to collect the same number of measurements at a wider variety of IV data points
f. use a new IV instrument but the same DV instrument to collect more DV measurements than before at the same IV data points
g. use a new DV instrument to take the same number of measurements as before at a greater variety of IV data points
h. start over to collect the same number of DV measurements as before, but at a greater variety of IV data points than before
