The sum of all scores (Xi) divided by their common number (N).
the sum of the values of a random variable divided by the number of values
An average found by adding the numbers in an array and dividing by the total number of items present.
The sum of all the measurements in a data set divided by the number of measurements in the data set.
The average of a set of numbers. The arithmetic mean of 8 and 4 is (8+4)/2, or 6.
calculated mathematical average.
The sum of the num- bers in a set divided by the number of numbers in the given set.
The arithmetic mean of a number of observations is the simple average of them. It is commonly referred to simply as the mean.
a type of average (measure of central tendency), which is defined as the sum of all the values in a set of numerical data divided by (where = # of values in the data set); this value is usually the most common usage of the word "average," and typically it is labeled as either ยต (lowercase Greek letter "mu") to denote a population mean or (referred to a " bar") to denote a sample mean
The arithmetic mean of a set of numbers (also called the average) is equal to the sum of the numbers divided by the number of numbers. For example, for the data set {1, 2, 3, 6}, the mean is (1+2+3+6)/4 = 12/4 = 3.
1. (Also called mean, average, simple average.) One of several accepted measures of central tendency, physically analogous to "center of gravity." Pertaining to a set of numbers , the arithmetic mean, usually denoted by the symbol , is the sum divided by . Since the word "mean" is also applied to other measures of central tendency, such as weighted means, geometric means, and harmonic means, the adjective "arithmetic" is used for clarity. However, when used without further qualification, the term "mean" is understood as arithmetic mean. Compare geometric mean. 2. Pertaining to a random variable, same as expected value.
The sum of a set of values divided by the number of values.
An average value of a data set calculated by determing the sum of all the numbers in the data set and dividing by the number of data values within the set.
In mathematics and statistics, the arithmetic mean (or simply the mean) of a list of numbers is the sum of all the members of the list divided by the number of items in the list. If one particular number occurs more times than others in the list, it is called a mode. The arithmetic mean is what students are taught very early to call the "average".
