Question 919273: a researcher takes 100 reading in an experiment. if he repeats the experiment 500 readings, find propbale error that will be reduced
by what factor the probable error is reduced * Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! ME = K/n^2 (K = zSD)... same for both experiments
ME1 = K/100^2 vs ME2 = K/500^2
ME1/ME2 = = 500^2/100^2 = 25
probable error is reduced by 1/25 with the larger sample
