Uncertainty in Measurement: Reading Instruments

49.7K
Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Uncertainty: Overview

1.4K
In analytical chemistry, we often perform repetitive measurements to detect and minimize inaccuracies caused by both determinate and indeterminate errors. Despite the cares we take, the presence of random errors means that repeated measurements almost never have exactly the same magnitude. The collective difference between these measurements - observed values - and the estimated or expected value is called uncertainty. Uncertainty is conventionally written after the estimated or expected value.

Uncertainty: Confidence Intervals00:54

Uncertainty: Confidence Intervals

10.0K
The confidence interval is the range of values around the mean that contains the true mean. It is expressed as a probability percentage. The interpretation of a 95% confidence interval, for instance, is that the statistician is 95% confident that the true mean falls within the interval. The upper and lower limits of this range are known as confidence limits. The confidence limits for the true mean are estimated from the sample's mean, the standard deviation, and the statistical factor...

Propagation of Uncertainty from Random Error00:59

Propagation of Uncertainty from Random Error

1.6K
An experiment often consists of more than a single step. In this case, measurements at each step give rise to uncertainty. Because the measurements occur in successive steps, the uncertainty in one step necessarily contributes to that in the subsequent step. As we perform statistical analysis on these types of experiments, we must learn to account for the propagation of uncertainty from one step to the next. The propagation of uncertainty depends on the type of arithmetic operation performed on...

Random Sampling Method01:09

Random Sampling Method

14.0K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest. Among the various sampling methods used by...

Uncertainty in measurements can be avoided by reporting the results of a calculation with the correct number of significant figures. This can be determined by the following rules for rounding numbers:

Area of Science:

  • Data Science
  • Bioinformatics
  • Computational Statistics

Background:

  • Handling uncertain data is a significant challenge in various scientific domains.
  • Traditional counting methods struggle with observations that lack precise referential association.
  • Possibility Theory offers a framework for modeling and quantifying uncertainty.

Purpose of the Study:

  • To develop a robust method for counting uncertain data.
  • To integrate Possibility Theory for representing and processing data uncertainty.
  • To provide a flexible counting approach with both exact and approximate variants.

Main Methods:

  • Data uncertainty is modeled using Possibility Theory, representing observations as possibility distributions.
  • A novel counting method is developed to incorporate these possibility distributions.
  • Two variants are proposed: exact counting (quadratic time) and approximate counting (linear time).

Main Results:

  • The method yields a fuzzy interval on the domain of natural numbers for each referent.
  • Exact counting provides the precise fuzzy interval, while approximate counting offers an estimate.
  • The method is demonstrated with a Python implementation and a Bioinformatics use case.

Conclusions:

  • The proposed method effectively counts uncertain data by leveraging Possibility Theory.
  • The availability of both exact and approximate counting variants enhances its applicability.
  • This approach offers a valuable tool for data analysis, particularly in fields with inherent data ambiguity.
