Average of the given set of values
- In statistics, the mean is one of the measures of central tendency, apart from the mode and median. Mean is nothing but the average of the given set of values. It denotes the equal distribution of values for a given data set.

Mean, median, and mode are different measures of center in a numerical data set. They each try to summarize a dataset with a single number to represent a "typical" data point from the dataset. Mean: The "average" number; found by adding all data points and dividing by the number of data points.

Mean is the simple mathematical average of a set of two or more numbers. The mean for a given set of numbers can be computed in more than one way, including the arithmetic mean method, which uses the sum of the numbers in the series, and the geometric meanmethod, which is the average of a set of products. However, all the primary methods of computi...
The mean is a statistical indicatorthat can be used to gauge performance over time. Specific to investing, the mean is used to understand the performance of a company’s stock price over a period of days, months, or years. An analyst who wants to measure the trajectory of a company’s stock value in, say, the last 10 days would sum up the closing pri...
Calculations for both the arithmetic and geometric means are fairly similar. The calculated amount for one will not substantially vary from another. However, there are subtle differences between the two approaches that do lead to different numbers.
Let’s put this into practice by examining the price of a stock over a 10-day period. Imagine an investor purchased one share of stock for $148.01. The price of the stock over the next 10 days is also included. The arithmetic mean is 0.67%, and is simply the sum total of the returns divided by 10. However, the arithmetic mean of returns is only accu...
Within business and investing, mean is used extensively to analyze performance. Examples of situations in which you may encounter mean include: 1. Determining whether an equity is trading above or below its average over a specified time period. 2. Looking back to see how comparative trading activity may determine future outcomes. For example, seein...
The mean is another word for a mathematical "average." The simple or arithmetic mean is the average calculated by summing up the values of some observations and dividing by the number of observations. The geometric mean is calculated by multiplying all the numbers in a dataset and then taking the nthroot of the product, where n is the total number ...
mean, in mathematics, a quantity that has a value intermediate between those of the extreme members of some set. Several kinds of means exist, and the method of calculating a mean depends upon the relationship known or assumed to govern the other members.

The mean formula to find the mean of a grouped set of data can be given as, x̄ = Σf i x/ i Σf i, where, x̄ is the mean, f i is frequency of a class and x i is mid-interval value of corresponding class.
mean, median, and mode, in mathematics, the three principal ways of designating the average value of a list of numbers. The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list.
