Which option identifies which of the two studies described has the more reliable data set and explains why?
Study 1: A survey was conducted 10 times, and the standard deviation was 7.8 percent of the mean.
Study 2: A survey was conducted 100 times, and the standard deviation was 14.5 percent of the mean.
Because the data distribution is more spread out as standard deviation increases, study 1 is more reliable.
Because the margin of error increases as sample size increases, study 1 is more reliable.
Because the data distribution is less spread out as standard deviation increases, study 2 is more reliable.
Because the margin of error decreases as sample size increases, study 2 is more reliable.
