First, look at what data your statistics are based on. Taking the statistics of kindergartens in a certain district as an example, the following data need to be collected;

1. Total number of kindergartens in the whole district

2. The total number of school-age children in this area

3. Total number of children entering the park in the whole region

4. The total number of preschool teachers in the whole region

5. Total number of registered preschool teachers in the whole region

6. The total number of teachers who have obtained qualification certificates in the whole region.

Second, with the total number of teacher qualification certificates as the statistical point, the following data can be obtained:

1. The number of kindergarten teacher qualification certificates accounts for the average number of certified teachers in the total number of kindergartens in the region (that is, the average number of certified teachers in each kindergarten in the region);

2. The number of certified kindergarten teachers accounts for the average number of certified teachers in the total number of school-age children in the region (that is, there are 1 certified teachers in the average number of school-age children in the region);

3. The number of certified kindergarten teachers accounts for the average number of certified teachers in the total number of kindergarten children in the whole region (that is, there is one certified teacher in the average number of kindergarten children in the whole region);

4. The number of certified kindergarten teachers accounts for the average number of certified kindergarten teachers in the whole region (that is, there are 1 certified kindergarten teachers in the whole region);

5. The number of certified kindergarten teachers accounts for the average number of certified kindergarten teachers in the whole region (that is, there is one registered teacher among the certified kindergarten teachers in the whole region);

Thank you for taking it as a satisfactory answer.
