What Is Arithmetic Mean?
Arithmetic mean (or simply mean) is one of the most important measures of central tendency, which is employed to summarize a set of numerical data by simply calculating the average of all the numbers Arithmetic mean is calculated by adding all the numbers in the data set and dividing the sum by the total number of points in the data set. Sometimes, the values of outliers are excluded while calculating the arithmetic mean of the data set. The arithmetic mean is also referred to as the average and is represented by the Greek letter mu (μ).
Arithmetic mean is an efficient tool to measure the central tendency of numerical data. It is used to identify the average value of a set of data points and helps to identify the distribution of the data points in relation to the mean. Arithmetic mean is commonly used as a part of descriptive statistics since it shows the middle value of the data set. It also helps to compare two data sets and identify the difference between them.
Examples of how Arithmetic Mean is Used in the Real World
1. Academic Performance: Arithmetic mean is widely used in the educational sector for measuring the student’s academic performance. By calculating the mean of the student’s grades, it gives an insight into their academic performance. It also helps the students to understand their overall performance in a particular subject and helps them to identify areas where they need to focus more.
2. Stock Market: Arithmetic mean is also used in the stock market to measure the average performance of the stocks and to understand the market trends. By calculating the mean values of the stocks, investors can have an idea of their investment performance. It also helps to identify the potential and growth of the stock in the long run.
3. Sci-Tech Industry: In the sci-tech industry, the arithmetic mean is used to measure the performance of the products. By comparing the arithmetic mean values, the companies can have an idea of the best-selling products and the products which need improvement.
4. Polls: In opinion polls, the arithmetic mean is used by organizations to measure the readers’ opinion. It helps to measure the views of the target audience on a particular topic. By calculating the arithmetic mean, it helps to identify the general opinion of the readers.
5. Weather Forecast: Arithmetic mean is also used to measure the temperature of a particular area. By calculating the mean temperature, the meteorologists can predict the weather of that particular area accurately. With the help of formula of mean values, they can get a better idea of the temperature range in the area and make a better forecast.
Overall, arithmetic mean is an essential tool to measure the central tendency of numerical data. It helps to analyze the data sets and identify the average value of the data points. It is widely used in the educational sector, stock market, sci-tech industry, polls and the weather forecasting industry.
