In social science, results with a 95% confidence level are accepted as significant.
The confidence interval is affected by three factors.Statistical analysis can be complex, and this article aims to explain some of the basic considerations, to an audience without an assumed mathematical background.At the end of this article there are a wide variety of links to further reading, which can help you through the process of statistical analysis.Statistical analysis, through a range of statistical tests, can give us a way to quantify the confidence we can have in our inferences or conclusions.Statistical analysis should only be used where there is a clear understanding of the reasons for doing so.Statistical analysis is a mathematical method of interrogating data.This is done by looking for relationships between different sets of data.The independent variable answers the question “What do I change?”, the dependent variable answers the question “What do I observe?Your review should provide information, interpretation, and evaluation.The information will help your reader understand the nature of the work under analysis.
