What is the margin of error


Discuss the below:

Q1: If a random sample of 10 people found that 9 were pro-life (i.e., 90%), while another random sample of 1000 people from the same population found that 550 were pro-life (i.e. 55%), which would you find to be more significant? Why? When pollsters report results of a poll, they often include the margin of error but not much more.

Q2: If candidate X has 54% support of the voters with a margin of error of 3%,that means the candidate is predicted to have between 51% and 57% support in the election. Before jumping to conclusions, what other information would you like the pollster to provide?
