What to Measure and How. Measurement generally refers to the assigning of numbers to indicate different values of variables. If your research involved determining if there was a relationship between height and weight of dogs, it would make sense to measure the height and weight of dogs using a scale.
From this, the lower end of the operating range is determined, which translates to: Minimum weight = 2000 Ã Repeatability (S.D.) Further, 3) When the S.D. obtained is smaller than 0.41d (d = scale interval), that S.D. is replaced with. 0.41d. Minimum weight is the minimum sample quantity required to perform an accurate quantitative. analysis with the measurement error of the balance used taken into account. If the sample quantity.
Weighing scales use a spring with a known spring constant (see Hooke's law) and measure the displacement of the spring by any variety of mechanisms to produce an estimate of the gravitational force applied by the object.
