Measurement: Standard Units

82.4K
Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

Uncertainty in Measurement: Accuracy and Precision

106.0K
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.

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...

The "center" of a data set is also a way of describing location. The two most widely used measures of the "center" of the data are the mean (average) and the median. The words "mean" and "average" are often used interchangeably. The substitution of one word for the other is common practice. The technical term is "arithmetic mean" and "average" is technically a center location. However, in practice among non-statisticians,...

The International System of Units or SI system, by international agreement, has fixed measurement units for seven fundamental properties: length, mass, time, temperature, electric current, amount of substance, and luminosity. These are called the SI base units.

Measuring Reaction Rates

Polarimetry finds application in chemical kinetics to measure the concentration and reaction kinetics of optically active substances during a chemical reaction. Optically active substances have the capability of rotating the plane of polarization of linearly polarized light passing through them—a feature called optical rotation. Optical activity is attributed to the molecular structure of substances. Normal monochromatic light is unpolarized and possesses oscillations of the electrical...

Summary

Pregnant women spend over half their waking hours sedentary. The Sedentary Behavior Questionnaire (SBQ) has low validity but can rank sedentary behavior levels compared to objective multi-sensor monitors (SWA).

Area of Science:

  • Obstetrics and Gynecology
  • Public Health
  • Kinesiology

Background:

  • Sedentary behavior is prevalent in pregnant women, potentially impacting maternal and fetal health.
  • Accurate measurement of sedentary time is crucial for understanding health risks and developing interventions.

Purpose of the Study:

  • To quantify and compare sedentary time in pregnant women using the Sedentary Behavior Questionnaire (SBQ) and a multi-sensor accelerometer (SWA).
  • To assess the concordance, correlation, and agreement between subjective (SBQ) and objective (SWA) measures of sedentary time.

Main Methods:

  • 186 pregnant women completed the SBQ and wore an SWA for at least 7 days.
  • Analysis included concordance, correlation, agreement, and relative activity levels between SBQ and SWA.
  • One-way ANOVA evaluated differences in sedentary time by day type and participant characteristics.

Main Results:

  • Pregnant women were sedentary for 64% of waking hours, with television viewing being the most common sedentary behavior.
  • Concordance, correlation, and agreement between SBQ and SWA were weak.
  • Significant correlations were found for weekday and average day sedentary time (r=0.23, P=0.001; r=0.20, P=0.008).

Conclusions:

  • Pregnant women exhibit substantial sedentary time, approximating half of their day.
  • The SBQ demonstrates low validity and agreement with SWA but shows potential for ranking individuals by sedentary behavior levels.
