a typed measurement - it can be a boolean value, a real number, a vector (in which case it's also called a data vector), etc

The value of a data item, as displayed in a cell of a sheet. A data point reflects the relationship between intersecting axis items in a crosstab. See: data item.

Observed data. A data point measured by some analytical technique expressed in two dimensions, usually concentration and time. There may be measurement error in either or both dimensions although it is often assumed that the error in any time measurements is zero.

location along the ground surface profile of the cross-section, identified by its horizontal distance from the zero point on the left side of the stream, looking downstream. Synonymous with station point.

In the context of hydrologic observations, a location on a river/stream for which observed data is input to RFC or WFO hydrologic forecast procedures, or included in public hydro­logic products. Flood forecasts and warnings are not issued for data points

A generic activity. For activities that occur outside of the system, a data point can be created as a way to link and rate automatically generated submissions.

In statistics, a data point is a single typed measurement. Here type is used in a way compatible with datatype in computing; so that the type of measurement can specify whether the measurement results in a Boolean value from {yes, no}, an integer or real number, or some vector or array. The implication of point is therefore that the data may be plotted in a graphic display, but in many cases the data are processed numerically before that is done.
