Master One-Sample T-Test in SAS | Data Analysis Made Easy
In this session of @analyticsschool, we'll be diving into the world of hypothesis testing using SAS. Specifically, we'll focus on performing a one-tailed t test in SAS.
The t test is one of the most common hypothesis tests in statistics. The t test determines either whether the sample mean, and the mean of the population differ or if two sample means differ statistically. The t test distinguishes between
one sample t test
independent sample t test
paired samples t test
The choice of which t test to use depends on whether one or two samples are available. If two samples are available, a distinction is made between dependent and independent samples. In this tutorial you will find everything about the one-sample t test. The one-sample t test is used to test whether the population differs from a fixed value.
We will be using Proc TTest procedure to conduct t test in SAS. The Proc TTest procedure in SAS performs t test and computes confidence limits for one sample, paired observations , two independent samples tests. Moreover, with ODS graphics, Proc TTest can also be used to produce histograms, QQ plots, box plots and confidence limit plots.
