SPSS is a professional data statistical analysis software that has many practical calculation functions in addition to statistical analysis. Similar to statistical analysis, the mathematical calculation function of SPSS is also designed for variables. After users define and input variables, they can use the built-in mathematical functions to perform mathematical calculations on the variables. Given the area of a square, how to solve for its side length is the simplest square root calculation. This article takes it as an example to explain how to input SPSS square symbols and calculate SPSS squares.
1. Enter data file
Open SPSS and the interface is shown in Figure 1. Click on File, New, Data, and create a new SPSS data file.
Figure 1: Creating a New Data File
Open the variable view, change the name of the first variable to square area in the default numerical format, and then click on the data view to enter square area data into the data file.
Figure 2: Setting Variable Attributes
Enter the square area value, as shown in Figure 3.
Figure 3 Enter square area
2. Calculate data files
After entering the data, click on "Convert" to calculate the variable. Enter the square edge length in the target variable, which represents that the calculation result will be output as a variable. The variable name is "Square Edge Length". Double click on the square area to add the variable to be calculated to the numerical expression. Then enter the expression "sqrt (Square Area)" shown in step 3, and click "OK". The system will perform square root calculation.

Figure 5 Calculation results
The calculation results are shown in Figure 5. SPSS has created a new variable called square edge length, and the calculation results correspond one-to-one with the square area.
For the convenience of users, SPSS has explained the built-in functions by selecting arithmetic from the function group shown in Figure 4, and then selecting SQRT from the functions and special variables below. This displays the format and requirements of the square root function of SQRT, as shown in Figure 6.

In addition to square, SPSS has a large number of built-in function calculation formulas. Interested users can use the method described in this article to view the meanings and expressions of functions for future use.
