I. Median There are many ways to calculate the median of a heap: 1. Mean, that is, average, returns the mean. 2. Median sorts the number in the median, and finds the data in the middle. If it is an even number, the two numbers in the middle are average. 3. mode and mode. The maximum frequency. 4. Mid-range. Range = MAZ-min, which is the range of the maximum value minus the minimum value and the number distribution. Mid-Rand is (MAX + min)/2, which is the middle value of the range. This ind

In layman's eyes, one of the things statisticians often do is to put together a bunch of assorted data, figure out a few inexplicable numbers, and then deduce a seemingly plausible conclusion from these numbers, just as alchemists used "Sage's stone" to turn a heap of stones into gold. The sixth chapter, should be the most abstract chapter of the book, is to introduce the statistics of "sage stone"-the principle of data simplification. From the point of view of information, the sample contains a

elementary statistics course, the two developed a language, and their first letters were r, so r became the name of the language. As the predecessor of the r language, the s language code can run in the r language environment without any modification. From this perspective, the two languages are almost equivalent. S language was born in the 1970s s by John M. under the leadership of chambers, the department of Bell's laboratory statistics shows the evolution of modern

, determine whether the equation is established, whether the model passed the test. When we import the dependent variable and several independent variable data into the statistic analysis software, in the output result, have R value, T value, f statistic, etc., how do we define whether pass test, the regression equation is feasible? Is it possible to analyze data or make predictions? Now on the study of "Women's tea" experience and engaged in

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 have no comparable functionality with Excel. Visual Studio. NET is also a Microsoft product. Visual Studio. NET is very convenient to

Taking our courses as an example, the teacher spoke very seriously, but many people do not have a statistical basis, which seriously affects students' understanding of the analysis process and results. Analysis software such as SPSS and SAS are excellent, but the results still need to be explained. The value of statistical exp

1. What is statistics: Optimization statistics are collected to describe the database and database objects in more detail. These statistics are used to select the optimal execution plan for SQL statements. The optimized statistics include: Table statistics (Table statistics): number of rows, number of blocks, average row length; Column statistics (column statistics): number of distinct values (Newcastle Disease) in column, number of nulls in column, data distribution (histogram ); Index statisti
