Why Excel is used for enterprise production reports Excel table generation and formula settings are very powerful and convenient. It is a powerful information analysis and processing tool. Especially Excel formulas, functions, and VBA languages are extremely powerful. I have tried other spreadsheet software and h

In general, we will use Excel to statistical test results, in addition to Excel, there are SAS and other software, but also can be statistical test results, I am also a beginner SAS, I would like to introduce you to the simple use of SAS, as I continue to learn statistical k

observation data distribution characteristicSingle-Variable value grouping: Applies to discrete variables with less variable values.Group distance Grouping: Applies to continuous variables with more variable values.Ex: grouping methods and their watchmaking processesStep1: Determines the number of groups. The determination of group number is mainly used for the observation of data characteristics, so it depends on its data characteristics.Step2: Determines the group spacing for each group. Grou

Key points of eigenvalue selection technique Wang LiminArticle Source: Network1. Characteristic valuesEigenvalue is an important concept in linear algebra. In mathematics, physics, chemistry, computer and other fields have a wide range of applications. Set A is an n-order matrix, if there are several m and not 0 N Willi Vector x, so that AX=MX is established, it is said that M is a eigenvalue or intrinsic value. A non-0 n Willi Vector x is called a eigenvector or eigen vector of the eigenvalues

output of data by shoot the head, and the mining algorithm is only to prove how clever your decision is. From the analysis output, data analysis can be presented in charts, text, tables, business derivation processes, or a series of advanced mathematical formulas. It is obvious that the charts are the most impressive, the second is the form, the worst text effect, and the last is the process or formula tha

-digit number respectively, the three digits of this three-digit number represent the coordinates of the three dimensions of 3x3x3 = 27 cube. H5 cell formula: = E5 * 100 + F5 * 10 + G5 Select E4 to H4, double-click the small black cross in the lower right corner, and copy the E4 to H4 formula to all customer data. The result is as follows: The next step is to count the number of customers on each cube. Use the pivot table to generate statistical res

1. Create tables in access as required, not limited to access, but also other data sources; 2. Open Excel and select the pivot table; 3. Select an external data source; 4. select new data source and fill in the data source link information. In this example, select the Access Table fact created just now; 5. In the query design wizard, select all fact columns; 6. Go to the "finish" Page and select "create OLAP multi-dimensional dataset;

In this article, we describe how to use Excel to quickly statistical results and analyze the results of the distribution of methods and procedures. 　　Preparing data Enter the necessary data, the worksheet is named "Total Table", with the political score (out of 100) in column D, for example, in cell E1~i1, below 60 (poor), 60 points and above (pass), 60-79 (Medium), 80-89 (good), 90 above (excellent).
