	AEJMC Archives -- September 1999, week 4 (#20)
		At the same time_those traditional sentinels of accuracy, [newspaper] editors and copy editors, are expected to focus more than ever on presentation of stories, less on their content."[4] While accuracy and credibility have become buzzwords in the news industry, the research literature is surprisingly devoid of recent study of errors in newspapers.
		Accuracy from the newsmakers' perspective is also important because they tend to be opinion leaders, the segment of the population that plays a strong role in shaping public opinion.[24] Moreover, newsmakers are essential to the news-gathering process; loss of trust can only impede the ability of journalists to do their work.
		Perhaps a stronger link between accuracy and credibility can be demonstrated by narrowing the focus and examining the relationship between errors and a newsmaker's overall view of the story in which he or she is quoted.

	Accuracy Assessment Procedures: Computational Issues
		However, if the accuracy of the estimate is required to be equal to or greater than the required value, a high-precision (narrow confidence interval) estimate will be preferable, because, with this requirement, the true value must lie at the lower edge of or outside the confidence interval.
		Only reporting the producers' accuracy as part of the accuracy assessment would give a completely misleading picture of data accuracy to users, who would interpret the 90% figure to mean that 90% of the polygons classified as class C in the data also have this class on the ground.
		For accuracy assessment purposes, investigators are typically interested in either a two-sided estimate or a one-sided estimate that expresses whether or not true value is at least equal to or exceeds the estimated value.

		Clearly the overall map accuracy is 90% but one could say that the accuracy of the forest class is 100% since all of the entire area of the forest class was accurately classified as forest.
		Producer’s accuracy is a reference-based accuracy that is computed by looking at the predictions produced for a class and determining the percentage of correct predictions.
		Consumer’s accuracy is a map-based accuracy that is computed by looking at the reference data for a class and determining the percentage of correct predictions for these samples.

		The overall ability of primary care physicians, hospital-based physicians, and families to predict patients' treatment preferences was examined initially with repeated measures analyses of variance (ANOVAs) using the overall accuracy, overtreatment, and undertreatment indexes (ie, collapsed across all scenarios and treatments).
		Overall, primary care physicians and hospital-based physicians were only accurate for an average of 0.66 and 0.64 of treatment decisions, respectively (Table 2), although accuracy scores differed by scenario.
		Accuracy scores were highest for "extreme" scenarios (ie, current health, coma with no chance of recovery, and terminal cancer with pain) when most patients wanted all or none of the treatment options.

		Accuracy is the amount by which a measured variable deviates from a value accepted as true or standard.
		Accuracy can be thought of in terms of individual component accuracy or overall system accuracy.
		For example, the overall accuracy of a wind speed measurement system includes the individual component accuracies of the cup or propeller anemometer, signal conditioner, analog-to-digital converter, and data recorder.

	Performance Benchmarking for Wireless Location Systems
		Accuracy criteria for wireless location systems have been the subject of much discussion due to the different interpretations and assumptions regarding the requirements that were stated in the FCC's recent wireless E-911 ruling.
		An overall system accuracy is then obtained by taking a weighted-average of the field measurements with the distribution of calls as shown for each environment.
		Characterization of both system accuracy and the estimation of accuracy for individual measurements can be simplified by defining a known geometry with a limited number of degrees of freedom.

	Accuracy Assessment Procedures: Implementation
		Accuracy assessment methodology depends to a considerable extent on the classification scheme used, the methods used for the original compilation of the data, and the accuracy requirements established for the data.
		A failure to meet accuracy specifications may result from improper procedures during the compilation of the map but may also be due to limitations inherent in the vegetation mapping process itself.
		Consistency and accuracy in photointerpretation depends on the identification of a clear and unambiguous relationship between the ground conditions and the photo signatures.

		Whether the load needs high accuracy on the output voltage, or if the headroom, or dropout voltage, of the overall circuit is very low can be deciding factors in which regulator is chosen for the application.
		The LDO that regulates that voltage should maintain tight initial accuracy of 1 percent with a worst case temperature variation of 2 percent, in order to allow for design margin and prevent the output voltage of the regulator from ever exceeding the maximum tolerance limits for the circuit design.
		Accuracy can also be critical in powering the ICs in the RF section responsible for the transmit and receive portions of the RF section.

		Monitoring accuracy can be improved through strategies such as having subjects generate their own problem-solving items or by monitoring their learning after a practice test of the material (Thiede et al., 2003).
		The first index was the monitoring accuracy score (calibration), which consisted of the absolute value of the difference between the confidence judgment and performance for each test item, summed over all items on a test and divided by the total number of items.
		Another estimate of the accuracy of student judgments was in the correlation between students' prediction of their final exam score and their actual score.

	Social Behavior and Personality: Is halo helpful? Effects of inducing halo on performance rating accuracy
		Acknowledging the possibility that halo error may have a beneficial effect on performance rating accuracy, we tested the effect of encouraging raters to inflate the degree of halo in their ratings.
		Cronbach derived four accuracy measures: Elevation (EL), the overall accuracy of the rater's mean rating; differential elevation (DE), accuracy in distinguishing between ratees; stereotype accuracy (SA), accuracy in discriminating between performance dimensions (averaging across ratees); and differential accuracy (DA), accuracy in rating individual patterns of strengths and weaknesses.
		To the extent that halo causes raters to rate according to a general impression, their accuracy in discriminating among dimensions of performance (averaged across ratees) should be diminished, which suggests the final hypothesis.

	Defining Data Accuracy
		Combine the accuracy of the ADC with the surrounding device circuitry and the overall DA system and you could end up with system accuracy of 3 to 100 parts in 65,536.
		Generally, accuracy is not constant over an entire measurement range; it varies with the reading magnitude—you'll find larger errors at the low end of the scale and more accurate results at the high end.
		The accuracy of the ADC is the difference between the average value and the actual applied value.

	ASNE - Accuracy Matters
		There is remarkable unanimity between the public and journalists on the fundamental value of accuracy and "telling it like it is," but both groups are skeptical about overall accuracy and would rather see journalists get it right than get it first.
		When they see errors, 19 percent of the public "always" sees a correction, and 40 percent "sometimes" see one (Table 5) A higher percentage of journalists notice corrections than the public (58 percent "always" see them), perhaps because journalists are paid not only to write, but also to read the paper more thoroughly.
		A slightly higher percentage of the newsroom sample - 33 percent of journalists overall and 47 percent of top editors - see factual errors in their daily newspaper more than once a week (Table 3 and Table 4).
