5.
Bill and Mike performed two different experiments to test the electronegativity of lithium. Their data tables are below. Whose data is more trustworthy and why?
a)
They can be trusted equally because they both did 5 trials.
b)
Bill's data is more trustworthy because the results of each of his trials are more consistent.
