In this session of @analyticsschool , we will discuss about how to find confidence interval in SAS. Confidence Interval is a range of values that is likely to calculate a population parameter with a certain level of confidence. Analyst often used confidence intervals at 95% confidence level for various statistical measure such as mean, standard deviation, variance, odds ratio etc.
We will learn how to find 95% confidence interval of mean using Proc Univariate, Proc Means & Proc TTest.
