How to calculate the standard deviation of fastening axial force
You need to apply for a live text license. Enterprises need to have the following conditions to deal with live network documents:
1, the operator is a company established according to law
2, the company's registered capital is more than 1 million
3, the company belongs to domestic enterprises
4, website domain name certificate
5, graation certificate of eight computer related personnel
6 Social security of three employees in the name of the company
the materials that enterprises need to prepare to apply for live network articles are as follows:
1, of business license
2, ID card of legal person and shareholder
3, articles of Association (need the latest, and the Bureau of instry and commerce should affix the file inquiry seal)
4, graation certificate and ID card of eight computer related personnel
5, ID card of company personnel, and mobile phone of personnel Email
6, company landline, legal person mobile phone, email
7, website domain name certificate (purchased in the name of the company)
8, some provinces need 1-3 network security officers

standard deviation formula: S = SQR (∑ (xn-xdial) ^ 2 / N)
in the formula, ∑ represents the sum, xdial represents the arithmetic mean of X, ^ 2 represents the quadratic power, and SQR represents the square root.
I don't know what you want to do, let me give you a link of variance.
standard deviation is the arithmetic square root of variance
floating point algorithm cumulative error setting rounding precision
applicable to:
Microsoft
Office
excel
2007
by setting the "display precision based" option before applying the number format to data, you can often prevent floating point rounding errors from affecting your work. This option forces each value in the worksheet to the precision shown on the worksheet
note
using the "display accuracy based" option will have a cumulative computational impact, making your data more and more inaccurate over time. Use this option only if you are sure that the display accuracy can maintain the accuracy of the data
click the office
button, and then click excel
options
Click advanced, then select the set precision to the displayed precision check box under when calculating this workbook, and then click OK
click OK
in the worksheet, select the cells you want to format
on the start tab, click dialog box launcher next to number
in the category box, click numbers
in the number of decimal places box, enter the number of decimal places you want to display
hint
to minimize the impact of cumulative errors in floating-point algorithms, you can also use the
round
function to round the number to the required number of decimal places.
standard deviation formula: S = sqrt formula, where ∑ represents the sum, X represents the mean value of X, ^ 2 represents the second power, and sqrt represents the square root
for example, there is a group of numbers 200, 50, 100, 200, and their standard deviation is calculated
standard deviation - a statistical term. A measure of the degree of dispersion of data distribution, used to measure the deviation of data values from the arithmetic mean. The smaller the standard deviation, the less these values deviate from the average, and vice versa. The size of the standard deviation can be determined by the standard deviation and... Then I have a lot of numbers. What should I do? Xwcataalysis (station contact TA) Excel software can be out, you import the data into excel, Excel software can calculate, how to get specific, search the Internet to know.
The calculation steps of sample standard deviation are as follows:
Step 1 (subtracting the average of all data from each sample)
Step 2: add the squares of the values obtained in step 1
Step 3, divide the result of step 2 by (n - 1) ("n" refers to the number of samples)
in step 4, the square root of the value obtained from step 3 is the standard deviation of sampling
the calculation steps of population standard deviation are as follows:
Step 1 (subtracting the average of all population data from each sample data)
Step 2: add the squares of the values obtained in step 1
in step 3, divide the result of step 2 by n ("n" refers to the total number)
in step 4, the square root of the value obtained from step 3 is the standard deviation of the population
standard deviation formula: S = SQR (∑ (xn-x dial) ^ 2 / N)
in the formula, ∑ represents the sum, X dial represents the arithmetic mean value of X, ^ 2 represents the second power, and SQR represents the square root<
I don't know what you want to do, so I'll give you a link of variance
standard deviation is the arithmetic square root of variance
Example: there is a group of numbers, which are 200, 50, 100 and 200 respectively. Find their standard deviation
x dial = (200 + 50 + 100 + 200) / 4 = 550 / 4 = 137.5
s ^ 2 = [(200-137.5) ^ 2 + (50-137.5) ^ 2 + (100-137.5) ^ 2 + (200-137.5) ^ 2] / (4-1) standard deviation s = sqrt (s ^ 2)
