In probability theory, the expected value (also called expectation, expectancy, expectation operator, mathematical expectation, mean, expectation value, or first moment) is a generalization of the weighted average. Informally, the expected value is the arithmetic mean of the possible values a random variable can take, weighted by the ...
The multi-stage fitness test (MSFT), also known as the beep test, bleep test, PACER test ( progressive aerobic cardiovascular endurance run ), or the 20m shuttle run test, is a running test used to estimate an athlete's aerobic capacity ( VO 2 max ). The test requires participants to run 20 meters back and forth across a marked track keeping ...
In computer science, best, worst, and average casesof a given algorithmexpress what the resourceusage is at least, at mostand on average, respectively. Usually the resource being considered is running time, i.e. time complexity, but could also be memory or some other resource. Best case is the function which performs the minimum number of steps ...
In statistics, a moving average ( rolling average or running average or moving mean [1] or rolling mean) is a calculation to analyze data points by creating a series of averages of different selections of the full data set. Variations include: simple, cumulative, or weighted forms. Mathematically, a moving average is a type of convolution.
The Yo-Yo intermittent test is aimed at estimating performance in stop-and-go sports like football (soccer), cricket, basketball and the like. It was conceived around the early 1990s by Jens Bangsbo, [1] a Danish soccer physiologist, then described in a 2008 paper, "The Yo-Yo Intermittent Recovery Test". [2]
Optimal. No. In computer science, selection sort is an in-place comparison sorting algorithm. It has an O ( n2) time complexity, which makes it inefficient on large lists, and generally performs worse than the similar insertion sort. Selection sort is noted for its simplicity and has performance advantages over more complicated algorithms in ...
In ordinary language, an average is a single number or value that best represents a set of data. The type of average taken as most typically representative of a list of numbers is the arithmetic mean – the sum of the numbers divided by how many numbers are in the list. For example, the mean average of the numbers 2, 3, 4, 7, and 9 (summing to ...
Covid rates are still rising across most of the country, fueled by the highly contagious new variants of the virus — KP.2 and KP.3 and LB.1. As of July 18, the highest levels of Covid are in the ...
