Coinmarketcap.com shows a price per coin. When I browse under markets of a coin, I see mostly a lot of different markets where the respective coin is traded. The prices are mostly different. Not much but sometimes up to 2-3%. Which price does coinmarketcap take? Is it the average of prices of all different markets? Or is it the one with the highest volume?

I always thought it was something like a volume-weighted average, so a mix of both your guesses.

[EDIT] Here:
How are the prices calculated for various the cryptocurrencies?

Price is calculated by taking the volume weighted average of all prices reported at each market. Sources for the prices can be found on the markets section on each cryptocurrency page. For example, Bitcoin's markets.

they collect all exchange's data  and obtain the coin's highest price and lowest price  last 24 hours

There isn't a price set by the exchanges the prices in the exchanges are set by the people there's a by Price there's a sale price and there's a 24-hour average and the information from those exchanges all falls into corn market cap and other sites like that besides don't set the sites they calculated based on simple three pieces or four pieces information.

Thanks a lot. I had already thought of the kind of price definition. This also makes the most sense.
I came up with the question because I had seen some coins (marketcap ranking 200+) that were listed on a few exchanges and which had a huge price difference and yet Coinmarketcap has a completely different price displayed, which did not open to me.

Your question can be compared to how does people appear and talk on the television screen, there are some scripts that pull data from those various exchange and cryptos trading sites then transmit those data to the coinmarketcap website.
