Statement I:
If a dataset has sufficient data points, then any statistical test will give us a significant conclusion.
Statement II:
Sufficient data points are not required for any statistical test to be conclusive. Statistical tests are only valid when the data follows certain underlying assumptions, such as normality.
Differences:
Focus on data amount: Statement I focuses on the data amount and how it affects the validity of statistical tests.
Emphasis on assumptions: Statement II emphasizes the importance of specific underlying assumptions about the data distribution for the test's validity.
Example:
Imagine you have a dataset with 10 data points, but the data is not normally distributed. Even though the data has 10 points, Statement I would still conclude that statistical tests are valid. However, Statement II would tell you that statistical tests would be unreliable due to the data's non-normal distribution
