Measurements are inherently uncertain and require careful analysis to interpret results accurately.
Different types of errors can affect data collection, including systematic and random errors, with each requiring different methods of identification and correction.
Graphical data presentation enhances understanding of relationships and trends in scientific data.
The extent to which a measured value corresponds to the true value.
The degree to which repeated measurements under unchanged conditions show the same results.
The digits in a measurement that contribute to its precision, indicating the uncertainty.
The process of determining the uncertainty in a result derived from measurements with uncertainties.
A method used to measure how matter interacts with electromagnetic radiation, used for identifying materials and measuring concentrations.
