1. First open spss, then click the analysis menu, and then select the factors in dimensionality reduction, as shown in the figure below.
2. Open the factor analysis window and move AC 1, AC2, AC3, AC4 and AC5 into the variable box.
3. Click the Description button to open the corresponding window, and check the initial solution, the correlation coefficient matrix and the coefficients of KMO and bartlett sphericity test.
4. Then click the Extract button to open the window to view the analysis correlation matrix, and display the unrotated factor solution and the gravel map.
5. Click the score button to open the factor score window, select Save As Variable, select Regression, and then click Continue.
6. Finally, set the option, check the missing value to exclude the number of columns, check the coefficient display format to sort by size, and then click Continue.
7. After confirmation, generate factor analysis results, including correlation matrix, KMO and bartlett test.
