4th Quarter Reflection

 My primary discovery is that the choice between a T-test and a Z-test isn't random; it's dictated by the story your data tells. I learned that both are parametric tests used to compare means, but their application hinges on specific conditions.

My biggest challenge was looking at a research problem and correctly identifying which specific test to use. I often got confused about whether the scenario called for a Z-test, an independent T-test, or a paired T-test. For example, distinguishing between comparing the means of two separate groups versus the same group at two different times was tricky.

Focusing on Examples: Instead of just memorizing formulas, I focused on analyzing solved examples and case studies. By seeing how the tests were applied in specific research contexts (e.g., medicine, business, psychology), I was able to better understand the connection between the statistical theory and the practical problem.

Moving On I will apply this lesson in future research, maybe in higher grade levels, by using T-test and Z-test to analyze and compare data accurately in my own studies.
