Statistics Beginners

Statistical Analysis is the collection, examination, summarization, manipulation, and interpretation of quantitative data to discover its underlying causes, patterns, relationships, and trends. Statistics is the science of mathematics dealing with the collection, tabulation and analysis of numerical facts. Statistical analysis is used to draw inferences made regarding characteristics or general principles about an unseen population based on the characteristics of the observed sample.

Statistical findings from a sample are generalized to pertain to the entire population. The process of drawing inferences, making predictions, and testing significance are examples of inferential statistics. Statistics are also used to describe only the observed group or sample from which they were derived; summary statistics such as percent, averages, and measures of variability that are computed on a particular group of individuals.
