First step: Are these independent samples? 2. Second Step: Do they have Equal variance? (Use F test two sample for variance) If the P value > 0.05, we will choose "t-test with equal variance". Otherwise, we will choose "t- test with unequal variance". 3. Third Step: Apply with the corresponding analysis to find the conclusion 4. Null Hypothesis 5. Alternative Hypothesis 6. One tail or Two tails
