objective questions on uncertainity in measurement

IB Chemistry Topic 11 Measurement MrWeng's IB Chemistry

11.1 Uncertainties and errors in measurement and results Qualitative data includes all non-numerical information obtained from observations not from measurement. Quantitative data are obtained from measurements, and are always associated with random errors/uncertainties, determined by the apparatus, and by human limitations such as reaction times.

Frequently-asked questions about Measurement Systems

The objective of an uncertainty study is to put bounds on a measurement (x plus/minus some interval). Generally a 95% confidence interval and the t-distribution is used since there are not a lot of observations taken. To do the study use one gage, one part, one part characteristic, and one operator.

1.5 Measurement Uncertainty, Accuracy, and Precision

Define accuracy and precision; Measured quantities have an associated uncertainty that is represented by the number of significant figures in the measurement. The uncertainty of a calculated value depends on the uncertainties in the values used in the calculation and is reflected in how the value is rounded. Measured values can be accurate
