[solved]-Statistical Theory

Introduction

Statistical theory is the basis for the techniques in study design and data analysis.
It covers approaches to statistical decision-making and statistics inference.
It gives ways of comparing statistical procedures.
Statistical theory is based on mathematical statistics.
It is linked to probability theory, utility theory, decision theory and optimization.
It provides a guide to comparing methods of data collection.

Major Concepts

Basic concepts to this theory includes the interpretation of probability as describing uncertain knowledge (i.e., Bayesian probability) is central.
Based on sampling theory, significant difference(p<0.05) between the two groups will occur in 1:20 cases of assigning participants to groups.

Application

To explain cause-and-effect phenomena.
To relate research with real-world event.
To predict/forecast the real-world phenomena based on research
Finding answers to a particular problem.
Making conclusions about real-world event based on the problem
Learning a lesson from the problem.

Conclusion

Statistical theory helps to choose between actions, so that the outcome is likely to be as good as possible, in situations with uncertainty.
