History of measurement

Figure 1: This line graph represents the prune’s weight in grams, in each beaker, over time. The prunes initial weight were all different, ranging from the heaviest prune in Beaker A, middleweight in Beaker B, and lowest weight in Beaker C. The weight of the prune in Beaker A increased at the fastest rate, followed by Beaker B and then Beaker C. Figure 2: This line graph represents the temperature of the water in each beaker, over time. The water’s initial temperature were all different,…

As primary Performance Evaluations Manager, I have met and exceeded all expectations within this critical element. All evaluations completed in this timeframe were completed in accordance with BUPERSINST 1610.1D, the updated version of the instruction. Generating and maintaining an accurate tracking system ensured a smooth process for the completion of all performance evaluations. Over 60 E6 evaluations were completed, consisting of 49 regular periodic, seven detachment, two special, and…

that reliability is the characteristic of reproducibility and consistency of the results of a measurement step. There are different types of test validity and reliability, for example, content validity, predictive validity, test-retest reliability and inter-observer reliability. For the test-retest reliability, the reliability of a research can be tested by managing the same procedure of measurement again to the same participants (Polgar, S. and Thomas, S.A., 2013). These two results should…

LINKAGES will proactively employ data quality assurance methods, including training, joint supportive supervision, mentorship and quarterly routine data quality assessment to continually assess, support the generation of, and improve data quality. Training and/or technical assistance will be provided on data collection, aggregation, reporting and quality control among all staff involved in routine data collection. The training will include implementing partners and health care workers at ART…

The two-point threshold experiment is meant to test a person's ability to perceive details on different parts of the body. Measurements varied on regions of the body depending on the size of their receptive fields. While the distance of the two points on my forearm was about three and a half centimeters, the distance between them on my upper arm was just barely four centimeters. Another example would be between my finger and thigh. The distance between the two points on my finger was 0.3…

their services? Is the weight or density of the shipment a factor? Explain this factor as part your answer. How does air carrier pricing relate to the value of goods being transportation? Load evaluating is reliant basically on weight and/or cubic measurements. A few shipments that have low thickness can be surveyed an over-dimensional charge, normally in light of 8 pounds for every cubic foot. This over dimensional charge is utilized to acquire proper income from shipment that take up a great…

Throughout scientific studies, researchers utilize sampling and conduct research that identifies probability and nonprobability, reliability, and validity of research. Also, scientists utilize telephone surveys, online surveys, focus groups, and surveys via websites when collecting data for research and need to be aware of the advantages and disadvantages of each of them. Sampling is the process of selecting a small part of a population for inspection and utilizing that smaller part of…

Outgassing of carbon dioxide (CO2) from inland waters has been estimated to offset approximately 20% of net uptake of carbon into the terrestrial biosphere. However, this calculation is based on estimates of source strength at the air-water interface that is highly uncertain [Ciais et al., 2013]. One of the largest unknowns is the accuracy and precision of freshwater partial pressure of CO2 (pCO2) estimates. To better understand observational uncertainty in CO2 flux from inland waters, here we…

Describe the sampling strategy. How appropriate were the various sampling design decisions? The sampling strategy is the first most important part of conducting this kind of research. According to Cooper and Schindler (2014) the most important characteristic of a sampling is to determine whether it represent the population it is supposed to represent. According to the article, “McMahon Group distributed mail surveys to 1,650 members and their spouses in January 1999” (Cooper & Schindler, NCRCC:…

II. The problem of study: The researchers suggest that dualism in villages’ socio-economic structure in Egypt is likely to bring different responses of rural population when they are exposed to same program or project of development. So far, it is not clear to what extent is this hypothesis valid to consider at both theoretical and empirical levels. Accordingly, planners and practitioners of development should consider the relationship between these two aspects, if it turned true, when planning…
