Classification Process of grouping Binary classification: Sorting objects into 2 groups based on a particular property Multistage classification Serial classification: sorting objects in a logical order on the basis of the extent or degree to which they demonstrate a common attribute Dichotomous key: a tool that scientists can use to help identify a particular specimen
Measurement Quantify variables using a variety of instruments and nonstandard/standard units Nonstandard units: it is difficult to consistently compare objects that cannot be held side by side Standard units: enable consistent descriptions and comparisons of measured objects that are not side by side and cannot be directly compared
Communication Convey information from one part to another Record data in multiple ways and present them to others
Inference Interpretation of observation Draw a tentative conclusion about objects, organism, or events base on observation and prior knowledge
You will find a line drawing of fossil tracks found in a layer of sandstone in Colorado. Your task is to make observations and inferences for each part.
Prediction Statements of future observation Make a forecast of a possible outcome of an investigation based on known patters in data Interpolation: between available data points p.39 Extrapolation: outside the collected data points p.40
