Kuidas leida andmekogumis kõige populaarsem toode?

To find the most popular product in a dataset, you typically need to define a popularity metric — for example, the number of sales, purchases, or views. Then, you can group the data by product and count the sum or number of relevant events for each product. In SQL, this might look like:

SELECT product_id, COUNT(*) AS popularity
FROM sales
GROUP BY product_id
ORDER BY popularity DESC
LIMIT 1;

In the context of machine learning, methods of ranking or clustering can be used if the data is more complex. But in most cases, simple aggregation and sorting allow you to determine the most popular product.
