The F-measure or balanced F-score, which combines precision and recall, is the harmonic mean of precision and recall. The performance of aggregated keywords is measured in terms of the overall performance of the application. However, this entails the influence of parameters besides the keywords ...
How can mean, median and mode contribute to the interpretation of data? A population of N = 20 scores has a mean of mu = 15. If 5 points are added to every score in the distribution, then the new mean would be: a) 20 b) 10 c) 15 d) 11...
On a measure of depression, the mean is 19 and the standard deviation is 3. What is the z-score for an actual score of 22? What are the z-score and the standard deviation? A group of quiz scores is shown in a histogram. If the...
that there exists an equilibrium with a threshold control that consists in choosing the maximal diffusion ratewhen the state is below a given threshold, and the minimal rateelse. The corresponding equilibrium distribution is the distribution of an oscillating Brownian motion at the terminal time. ...
statistics - a branch of applied mathematics concerned with the collection and interpretation of quantitative data and the use of probability theory to estimate population parameters normal - conforming with or constituting a norm or standard or level or type or social norm; not abnormal; "serve win...
The observational research designs (cross-sectional, cohort, and case-control) reporting on the proportion of oral hygiene and/or the mean OHI-index value among children diagnosed with cerebral palsy in Asia and/or Africa were considered. Outcome of interests The oral hygiene proportion and/or ...
in health and obesity-related research . . . Failure to account for RTM often leads to errors in interpretation of results and unjustified conclusions. In pre-/poststudy designs that lack a comparator control group, neglecting RTM can lead to the inaccurate conclusion that an intervention ...

All such mea- sures are used in situations where data sets contain some variation (i.e., not every score has the same value). The aim in calculat- ing one of these measures, then, is to generate a value that sits somewhere in the middle of the distribution of scores. On the ...
Parental obesity plays a critical role in the mental and physical health of the offspring in many stages of their lives. The existing body of research indicates that if at least one parent is obese, the children are at high risk of obesity as early as age 2 [1]. The risk is higher if...
