For this tutorial, we’ll explain how to calculate thearithmetic meanwhich is known in math as the average. To obtain the result, yousum your group of valuesand divide the result by the number of values. As an example, you can use these equations to find the average, or mean, for num...
Although a yearly average will give you a good idea of what average return to expect over a number of years, it is often not useful for predicting what will occur for any one year. For example, if an investment returned $10,000 in one year and lost $9,000 the next year, the yearly...
[解析] Arithmetic Statistics In the list of integers from 200 to 400 inclusive, the middle value is 300. For every integer above 300, there exists an integer below 300 that is the same distance away from 300; thus the average of the integers from 200 to 400, inclusive, will be kept at...

The Social Security benefits formula might seem complicated, but it's not too difficult once you break it down. You may not be able to precisely calculate your benefit if you're too young for Social Security, but keeping these guidelines in mind can help you squeeze the most money possible...
However, when we want to know the average of annual returns that are compounded, the simple average is not accurate. Returning to our earlier example, let's now find the simple average return for our three-year period: 15% + -10% + 5% = 10%10%/3 = 3.33% Claiming that we earned...
Note that the CAGR annualized rates are slightly lower than the arithmetic average of the two years’ individual growth rates. Limitations of Growth Rates While growth rates are important for understanding how things change over time, they do come with some important limitations. First, the growth...
