Margin of Error

What is the margin of error? How do we calculate it? Will we need to just calculate this margin of error or as well as the critical value and the standard error of statistic?

Margin of error is your critical value multiplied by your standard error. CV is found from the table on your formula sheet, and SE is listed on your formula sheet as well.

You can find it by dividing the range of your CI by 2
