There are two types of statistics: The general idea of statistical analysis is to summarise and analyse data so that it is useful and can inform decision-making.

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.The independent variable answers the question “What do I change?”, the dependent variable answers the question “What do I observe?Statistical analysis is a mathematical method of interrogating data.This is done by looking for relationships between different sets of data.54% of households felt that crime had the largest impact on their quality of life.Using a 95% confidence level a confidence interval of 3.01 can be assumed.The relationship between the confidence interval and sample size is not linear.An example can be found below: The confidence interval is also determined by the percentage of the sample that provides the same answer.In some situations we can examine the entire population, then there is no inference from a sample.In statistics, a result is called statistically significant if it is unlikely to have occurred by chance.
