      Area is almost the same as the confidence level –but you have to add one tail to get (in essence) the right limit, or critical T-value. For example, find the critical value of T for a 95% confidence when the sample size is 15 ... Calculate R Value (Linear Regression) ...

      below the mean GDP/CAP value of 5860. This tells us that that the median value of 2995 may be a better measure of the center for the GDP/CAP data because there are too many outliers in either direction of the mean. The box and whisker plot below also shows that the outlier value of 23474 makes the right whisker longer than the left.
