Document Summary
Statistics: the science of collecting, organizing, summarizing, and analyzing information to draw conclusions or answer questions: in addition, statistics is about providing a measure of confidence in any conclusions. Data: the information referred to in statistics: data can be numerical such as height or non-numerical such as gender. Either way data describe characteristics of an individual. Anecdotal: means the information being shown is based on casual observations and not on scientific research. Lurking variable: an explanatory variable that was not considered in a study, but that affects the value of the response variable in the study: they are typically related to explanatory variables considered in the study. Such as mothers breastfeeding babies the study first found breastfed babies have higher iqs than non-breastfed but it turns out that mothers who decided to breast feed typically had higher iqs and thus transferred the trait.
