How to rank with the rank function
Steps to rank with the rank function are as follows:
Tools/materials: LenovoG700, Windows 10, Excel2021.
1, select the cell to enter the excel software interface, next to your data, select a blank cell, double-click on the cell until the cursor begins to blink.
2, enter the function in the cell to enter the equal sign, in the input rank, double-click the first function that pops up.
3, enter the sorted data select your first data cell, enter a comma, and then select all your data, all the data in the letters and numbers before the symbols connected.
4, press the Enter key can then press the Enter key, hold down the bottom right corner of the cell to pull to the end you can see the results calculated with this function.
rank function:
rank function is a ranking function. rank function is most commonly used to find a value in a region of the ranking. rank function syntax form: rank (number, ref, order).
Function name behind the parameters of the number for the need to request the ranking of the value or cell name (cell must be digital), ref for the ranking of the reference value of the region, the order of 0 and 1, the default do not have to enter, get the rankings from the big to the smallest, if you want to ask the penultimate, the value of the order, please use the value of 1.
Positive ranking: in cell B2 for 20 the value of the ranking. B2 cell for the value of 20 in the A1: A5 region of the ranking, and did not enter the order parameter, do not enter the order parameter, the default order value of 0, that is, from high to low ranking. In this example, the positive ordering of 20 in the A1:A5 region is 1, so the displayed result is 1.

rank function ranking how to use (use methods)
In the process of data analysis and data processing, it is often necessary to rank the data in order to better understand the distribution and ordering of data. In the SQL language, you can use the rank function to realize the ranking operation on the data. In this article, we will introduce the use of the rank function, and give detailed steps.
I. The basic concepts and functions of the rank function
The rank function is a window function that is used to perform ranking operations on data. It can sort the data and assign the corresponding rank value according to the specified sorting rules. the basic syntax of the rank function is as follows:
“`
RANK()OVER(PARTITIONBYcolumnORDERBYcolumnASC/DESC)
“`
Which , the PARTITIONBY clause is used to specify the columns to be grouped, and the ORDERBY clause is used to specify the columns to be sorted and the sorting method (ascending or descending). the rank function will return an integer value indicating the rank of each record within the specified grouping.
Second, using the rank function to rank the steps
The following will introduce the use of rank function to rank the specific steps.
1. Create a data table
First of all, you need to create a table containing the data to be ranked. You can use the CREATETABLE statement to create the table and use the INSERTINTO statement to insert data into the table.
2. Write a SQL query statement
Next, you need to write a SQL query statement to rank the data using the rank function. The basic structure of the query statement is as follows:
“`
SELECTcolumn1,column2, … ,RANK()OVER(PARTITIONBYcolumnORDERBYcolumnASC/DESC)ASrank_column
FROMtable_name
“
Which column1,column2, etc. denote the name of the column to be queried and table_name denotes the name of the data table.
3. Execute the SQL query statement
Execute the written SQL query statement in the database management system to get the result set containing the ranking information.
4. Viewing the ranking results
Finally, you can view the query results to understand the ranking of the data. The ranking information will be presented in the result set as rank_column.
Three examples
In order to better understand the use of the rank function, the following is a specific example demonstration.
Suppose that there is a table of student grades, containing the names and grades of students. Now you need to rank the student grades in order to know the rank of each student in the class.
1. Create a data table
First, create a data table named “student” with two columns, “name” and “grade”. You can use the following SQL statement to create the table:
“`
CREATETABLEstudent(
Name VARCHAR(20),
GradesINT
);
““
2. Insert data
Then, insert data into the table “student”. student” table. You can use the following SQL statement to insert the data:
“
INSERTINTOstudent(name,grades)VALUES(‘Xiaoming’,90);
INSERTINTOstudent(name,grades)VALUES(‘Xiaohong’,85);
INSERTINTOstudent(name,grades)VALUES(‘Xiaogang’,95);
INSERTINTOstudent(name,grades)VALUES(‘Xiao Li’,80);
INSERTINTOstudent(name,grades)VALUES(‘Xiaohua’, 88);
“`
3. Ranking using the rank function
Next, write a SQL query statement that uses the rank function to rank students’ grades. The query statement is as follows:
“
SELECTName,Grade,RANK()OVER(ORDERBYGradesDESC)ASRank
FROMstudent;
“
4.Execute the query statement
Execute the above in your database management system. query statement to get the result set containing the ranking information.
5.Viewing the Ranking Results
Finally, view the query results to see the name, grade and ranking information for each student.
Through the above sample demonstration, you can see how to rank using the rank function. By specifying the sorting rules and grouping columns, you can perform flexible ranking operations on the data, making it easy to analyze and understand the data.
In summary, the rank function is a very useful data processing function that can easily perform ranking operations on data. Through the methods and steps introduced in this article, I believe the reader has mastered the use of the rank function, and can be flexibly used in the actual data analysis work.
rank function ranking how to use
rank function ranking can be used in Excel. rank function is mainly used for sorting, you can return to a column of numbers of the number of figures ranked, the number of its ranking is relative to the size of the other values in the list; grammatical format is “RANK (number, ref, [order]) “. Simply do a demonstration, then here is = RANK (E15, E15:E22). Finally, because to batch processing operations, then you can area references can be added to the absolute reference, then there is =RANK(E15, $E$15:$E$22), and finally drop down to complete.
rank function example
Positive ranking in this case we are in cell B2 for the value of 20 in the A1: A5 region of the ranking, we did not enter the order parameter, do not enter the order parameter, the default value of the order is 0, that is, from the highest to the lowest order. In this example, 20 in the A1:A5 region of the positive ranking is 1, so the results displayed is 1.
Inverse ranking in this case we are in the case of the above example, the value of order will be entered into the 1, found that the results have changed dramatically, because the value of the order of 1, meaning that the ranking of the inverse of the request for the 20 in the region of the inverse of the ranking of the A1:A5 is 4.

The method of ranking using the rank function is as follows:
1, open the table.
2, select a blank cell.
3, click the menu bar in the formula.
4. Select the Insert Function option.
5. Enter the rank function in the Find Function toolbar.
6. Click on the OK button.
7. In the Value column, select the parameter for ranking.
8, in the reference column box to select the parameter range of the ranking.
9, and then click OK.
10, and finally the results will be automatically filled.
In summary: the use of rank function ranking method is in the formula menu bar to insert the rank function, in the numerical menu bar to select the parameters of the ranking, in the reference to a column of the box to select the ranking range, and finally click OK to rank.
