To calculate a confidence interval (two-sided), you need to follow these steps: Let's say the sample size is 100. Find the mean value of your sample. Assume it's 3. Determine the standard deviation of the sample. Let's say it's 0.5.

An average speed of 26.7 m.p.h. with a standard deviation of 3.33 m.p.h are calculated from this dataset. WebThe lower and upper bounds of the confidence interval are found by subtracting and adding the margin of error ( E) from the point estimate ( p ^ ). In our example the point estimate was 0.2 and the margin of error was 0.143, then: The lower bound is: p ^ − E = 0.2 − 0.143 = 0.057 ― The upper bound is: p ^ + E = 0.2 + 0.143 = 0.343 ― indigenous radio calgary
