Explain and Execute Statistical Design and Analysis of Two Variable Hypothesis - Statswork

In this blog, I will explain to you how the statistical analysis is being applied for two independent samples. In practice, the test statistic used for comparing the two means from a population is by using the t-test because t-test shrinks the data to a single t-value and it is then compared with the significant value for the final conclusion. Now, let us understand the theoretical background in performing the t-test for two variables. Suppose X1 and X2 be the two independent random variables and let, be the sample with size n1 and n2 from a population with mean µ1, µ2 and variance σ12, σ22 respectively. Understanding the Problem Statement The primary or basic task in any statistical data analysis is to know or find out what the problem is and how the data is being measured. Construction of Test Hypotheses Once you understand the problem at hand, the next step is to frame an appropriate hypothesis to test for statistical s...
