Setting Confidence Levels. Normally you will not need to change anything in this section. People usually use symmetrical 95% confidence intervals, which correspond to a 2.5% probability in each tail. If you want a different confidence level, you can replace the 95 with your preferred level, then click the Compute button.

Alpha: This is the sign which is at 1 confidence level; if 90% is the confidence level, then significance level 0.10. Standard Deviation: This is the SD of the data range. Size: The number of observations in the data set. To compare the confidence interval value, we need to further calculate the mean of the data set. We will see some of the examples to understand practically.
