HemOnc.org is the largest freely available medical wiki of interventions, regimens, and general information relevant to the fields of hematology and oncology. It is designed for easy use and intended for healthcare professionals. Disseminated intravascular coagulation (DIC) involves abnormal, excessive generation of thrombin and fibrin in the circulating blood. During the process, increased platelet aggregation and coagulation factor consumption occur.
Please provide numbers separated by a comma to calculate the average of the numbers.
What is an average?
The term average has a number of different meanings. Most generally, it is a single number that is used to represent a collection of numbers. In the context of mathematics, 'average' refers to the mean, specifically, the arithmetic mean. It is a relatively simple statistical concept that is widely used in many areas.
The equation below is one of the more commonly understood definitions of the average:
| Average = |
|
where the sum is the result of adding all of the given numbers, and the count is the number of values being added. For example, given the 5 numbers, 2, 7, 19, 24, and 25, the average can be calculated as such:
| Average = |

| = |

| = | 15.4 |
ASH has developed a series of brief, evidence-based pocket guides to help physicians provide quality care to patients. The guides cover such topics as thrombocytopenia in pregnancy, heparin-induced thrombocytopenia, red blood cell transfusion, anticoagulant dosing and management, and von Willebrand disease.
The pocket guides are available as a mobile application for iOS and Android devices and as a mobile-friendly website. Free printed copies are also available to order.
