sql server - Is there an appropriate way to show correlation or causation from a SQL query? -


If there is a way that can provide a function to show correlation or earnings from Microsoft Access or SQL Server SQL, then I Be curious and select the results and its results.

This is basically a case scenario:

Assume that you have two tables, table student carservehys and table online course review . At the forefront, most of these two tables are unrelated, but the curriculum may be based on name, for example "England 101".

studentCourseServveys is a table that captures the data that students submit to their individual course surveys at the end of one semester. For example, in the last days of class students, on the basis of those things, the form is obtained to rate the train such as "the exams were related to the actual lecture material", "the trainer was ready on time" and then the end They have short answer opportunities to give them additional comments in

Online Counselio is a table used by the internal department which reviews content on the online component of the courses. For example, there are individual teaching designers in this department who have submitted various courses to the Blackboard for review. They review the content, delivery, curriculum structure and so on and so forth. After this the course is given its comments, scores, etc.

As already mentioned that most of the tables will be unrelated but we say that someone wants to show a relation that the results of online course reviews can in some way indicate that these online reviews Due to the quality of the overall course was better and it was shown in the students' reactions on the basis of their survey. result. (Basically, there are course surveys in the curriculum with an online course review score of 10, where a great majority of students evaluated it as excellent, the content was relevant, the teacher was ready, etc., to indicate That improvement in the online course has been translated to improve the quality of the individual and the overall category.)

It is almost a statistician A looks like a unique job, but I want to know whether this query can be shown on a query basis, in Access or SQL Server, I know that you can easily easily have two tables with a foreign key And then in a statement can get the results of a survey and review of the online course, but it does not really say anything. I think that in order to show any kind of relationship you will need to clarify any trend in any given period.

Thank you.

I would suggest creating a query with three values ​​- the name of the course (for example, ENG101 ), Student ratings and online course rating. In SQL Server, you can save the result as a .csv file. Do this, then open it in Excel and use R-Square to find two or three columns. Closer to R Square 1, close to two matches. 1 means a complete correlation of 0 does not mean any relation, and 1 means related, but in a polar opposite way
