Answer
Using larger sample sizes tends to decrease the variability of sample means, thus increasing the precision of the estimates obtained from the experiment.

Answer
Validity refers to the accuracy of a measure in terms of measuring what it is supposed to measure. Larger sample sizes do not directly improve validity, as validity is more related to the experimental design.
Step 4

Answer
Using large sample sizes reduces uncertainty in the estimation process, allowing for more accurate conclusions to be drawn from experimental results.
