Then, after a careful analysis, you will be able to pick and use the best method to reach your goal. One strategy is just to invest in larger samples, but another is to do more to systematically reduce even mean-zero errors so that, for a given sample, results are more precise.

Advantages and disadvantages of data collection: the winner is To resume, no methodology can be considered better than the others. Data collected is very accurate in nature and also very reliable.
