Uncertainty in Measurement: Accuracy and Precision
0 Views •
2020
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value. Suppose a quality control...

The Precision of Visual Working Memory with Delayed Estimation

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Human memory is limited. Throughout most of its history, experimental psychology has focused on investigating the discrete, quantitative limits of memory—how many individual pieces of information a person can remember. Recently, experimental psychologists have also become interested in more qualitative limits—how precisely is information stored? The concept of memory precision can be both intuitive and elusive at once. It is...
FAQs
Uniform treatment depends on coordinating several operating variables rather than adjusting one setting alone. Spray volume determines how much liquid reaches the target, nozzle pressure influences delivery conditions, droplet characteristics affect deposition, and travel speed changes the application rate across the surface. Controlling these factors together helps researchers reproduce treatment rates and compare responses among experimental samples.
Travel speed helps determine how long the spray reaches each portion of a test surface during an application. If speed changes, the delivered treatment rate may also vary even when the liquid and nozzle settings remain unchanged. Maintaining a controlled speed therefore reduces differences between samples and supports more consistent measurements of plant, soil, or surface responses.
Droplet delivery affects where applied liquid is deposited and how consistently it reaches the intended target. A precision bench sprayer allows researchers to examine deposition under controlled application conditions while limiting unnecessary variation between samples. This is important when studying pesticide efficacy, plant responses, or potential off-target movement, because differences in delivery can influence both treatment effects and environmental exposure observations.
The instrument provides a controlled small-scale setting in which researchers can examine treatment rates, spray deposition, and biological responses before connecting those findings with field-based assessments. Laboratory-scale control reduces variation and material use, making it easier to compare experimental conditions. Field studies then provide broader assessment context, while bench testing helps clarify responses under standardized application conditions.
A basic workflow is to place the plant, soil, or other test surface in the application area, prepare the liquid treatment, and establish the intended spray volume, nozzle pressure, droplet delivery, and travel speed. The sprayer then applies the treatment under those controlled settings. Keeping the same conditions across samples supports reproducible treatment rates and meaningful comparisons.
Researchers can use the system to investigate how agricultural chemical treatments affect plants or soil, how effectively a pesticide reaches its target, and how spray deposition varies under controlled conditions. It can also support studies of potential off-target movement. These applications generate comparable small-scale observations while reducing material use and helping relate laboratory findings to environmental assessments.
