Hi. I'm having a problem with this challenge.
"-- Calculate the average rating for each movie and round it to one decimal place"
Here's my attempt:
SELECT ROUND(0, 1) AVG(rating) FROM reviews;
Output:
Error: near "(": syntax error
I would appreciate any feedback please.

SELECT title, ROUND(AVG(rating), 1) AS average FROM reviews GROUP BY title;

SELECT movie_id, ROUND(AVG(rating), 1) FROM reviews GROUP BY movie_id;
