"The Flesch–Kincaid" (F–K) reading grade level was developed under contract to the U.S. Navy in 1975 by J. Peter Kincaid and his team. [1] Related U.S. Navy research directed by Kincaid delved into high-tech education (for example, the electronic authoring and delivery of technical information), [2] usefulness of the Flesch–Kincaid readability formula, [3] computer aids for editing tests ...
A vernier scale (/ v ə r ˈ n iː ˈ ə r / ver-NEE-er), named after Pierre Vernier, is a visual aid to take an accurate measurement reading between two graduation markings on a linear scale by using mechanical interpolation, thereby increasing resolution and reducing measurement uncertainty by using vernier acuity to reduce human
Accuracy is also used as a statistical measure of how well a binary classification test correctly identifies or excludes a condition. That is, the accuracy is the proportion of correct predictions (both true positives and true negatives) among the total number of cases examined. [10] As such, it compares estimates of pre- and post-test probability.
Validity [5] of an assessment is the degree to which it measures what it is supposed to measure. This is not the same as reliability, which is the extent to which a measurement gives results that are very consistent. Within validity, the measurement does not always have to be similar, as it does in reliability.
In other words, the results showed that having your arm resting in the lap during a blood pressure reading may lead to an overestimated systolic blood pressure measurement by 3.9 mm Hg and an ...
The Lexile Framework for Reading is an educational tool that uses a measure called a Lexile to match readers with reading resources such as books and articles. Readers and texts are assigned a Lexile score, where lower scores reflect easier readability for texts and lower reading ability for readers.
Blood pressure readings may not be accurate unless a person’s arm is positioned correctly, a new study suggests. A comparison of blood pressure readings taken while people held their arms three ...
(This is true of measures of all types—yardsticks might measure houses well yet have poor reliability when used to measure the lengths of insects.) Reliability may be improved by clarity of expression (for written assessments), lengthening the measure, [9] and other informal means. However, formal psychometric analysis, called item analysis ...
