Solution

The function in SQL that returns the average value of a numeric column is AVG(). Here is how you can use it:

  1. First, you need to select the column you want to find the average of. Let's say the column is called "Numbers" in a table called "Table1".

  2. Then, you use the AVG() function. Your SQL query would look like this:

SELECT AVG(Numbers) 
FROM Table1;
  1. Run this query in your SQL environment. The result will be the average value of all the entries in the "Numbers" column.

Remember, the AVG() function can only be used with numeric columns.
