IQ classification. Score distribution chart for sample of 905 children tested on 1916 Stanford–Binet Test. IQ classification is the practice of categorizing human intelligence, as measured by intelligence quotient (IQ) tests, into categories such as "superior" or "average". [1] [2] [3] [4]
Profit margin is a financial ratio that measures the percentage of profit earned by a company in relation to its revenue.

Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. [2] [7] These contrast with benign tumors, which do not spread. [7] Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. [1]
The mean values for 164 men and 156 women were 0.148 g/L/h and 0.156 g/L/h respectively. Although statistically significant, the difference between sexes is small compared to the overall uncertainty, so Jones recommends using the value 0.15 for the mean and the range 0.10 - 0.25 g/L/h for forensic purposes, for all subjects.

Percent-encoding. URL encoding, officially known as percent-encoding, is a method to encode arbitrary data in a uniform resource identifier (URI) using only the US-ASCII characters legal within a URI. Although it is known as URL encoding, it is also used more generally within the main Uniform Resource Identifier (URI) set, which includes both ...
Tight building design, including energy-efficient windows, well-sealed doors, and additional thermal insulation of walls, basement slabs, and foundations can reduce heat loss by 25 to 50 percent. Dark roofs may become up to 39 °C (70 °F) hotter than the most reflective white surfaces. They transmit some of this additional heat inside the ...
Introduction. In a classification task, the precision for a class is the number of true positives (i.e. the number of items correctly labelled as belonging to the positive class) divided by the total number of elements labelled as belonging to the positive class (i.e. the sum of true positives and false positives, which are items incorrectly labelled as belonging to the class).
In general, an n-log reduction means that the concentration of remaining contaminants is only 10 −n times that of the original. So for example, a 0-log reduction is no reduction at all, while a 1-log reduction corresponds to a reduction of 90 percent from the original concentration, and a 2-log reduction corresponds to a reduction of 99 ...
