Understand Data
Data are recorded information; ask who collected them, how, when, with what tool, and whether anything is missing.
Data do not mean only numbers. Descriptions, categories, images, and recorded observations can also be data. Both 'data are' and informal singular 'data is' occur in modern English; formal science often uses the plural.
Students classify sample data as qualitative or quantitative, identify a likely collection method, and critique a flawed data table for missing units, labels, or values.
What makes data useful and trustworthy? Compare how completeness, accurate tools, consistent methods, and bias can affect a data set.
