He didn't find a correlation, or rather found that there is no correlation, between proximity to a railway station and how the kebab is reviewed. It's a nice study for a statistics class!
Let x=[-5..+5] and y=[25,16,9,4,1,0,1,4,9,16,25] (that is, x²). The Pearson correlation coefficient, R², will be zero. We know that y is dependent on x, but isn't linearly dependent.
LOL we may need to update the title of this post, half the top level comments right now are assuming the study confirmed the hypothesis. > With a mighty Pearson's correlation of 0.091, the data indicates that this could > be true!

> be true! If you ignore the fact that the correlation is so weak that calling it 'statistically insignificant' would be quite generous. I actually came to a different conclusion than the author. Here is the way I'm thinking about the presented statistics: 1. There is 17 Kebab shops (out of 400 samples) with a google review lower than 3 stars. Let's call them "bad kebabs". 2. All those "bad kebabs" actually located w…
At least here, the majority of 1-2 star reviews are actually complaining about third-party delivery services like Foodora[1].
Of course the fries will be soggy and the burger luke warm when you got a guy who had to pedal a bike for half an hour to deliver it for you. Like what did you expect?

> but you can clearly see that the bottom-right quadrant of the plot is basically empty, which is an important insight. I don't think so? It's mostly a result of the fact that (obviously) the best place to sell food is where there are people, which is also the best place to put a metro station. So on average the kebabs are pretty good and on average they're near a station. In Figure 9 one of the worst reviewed restau…
> but the way you can tell it's the best place for a kebab is how late it's open every night That logic definitely does not apply to SF Bay Area. Most of the places that stay open are all pretty meh. A few pizza by the slice places, Dennys, Grubstake, Orphan Andy's, Mel's. Oakland and LA (SoCal) are no better. AFAIK most places have no interest in staying open late. Maybe they don't want to stay up. Maybe they don't…

TFA mentioned several ways in which Google reviews aren't an ideal tool here. Tossing out a couple more, you (1) don't have the same people giving reviews at each location, and (2) have a bias in those who choose to give reviews. As a point of anecdata about (1): Saturne in Paris (now closed) served some of the best food I've ever eaten, and it had lower ratings than a tourist-trap fish place on a pier near to where…

this reminds me my experience: when I went to Salt Lake City and wanted to try Turkish food and picked nearest Turkish restaurant with the the highest reviews from google maps. Interior was authentic and nice, but the food turned out to be AWFUL, kebab was burnt to ashes, everything food wise was horrible. When I complained, the cook came back and apologized, and I saw the cook was White American. Not saying all Amer…
My family members from Iran and Syria have said that people there cook beef extra because it's usually not very fresh, unless they're rich. So overcooked beef may be the more authentic way, depending on how you look at it. Lamb is more common anyway.

I'm never going to look at ratings. The only use there is photos of menus, food, and the restaurant itself.
I sort ratings by worst but look at the reason. If the 1 stars are "the waitress was rude", then that's fine. I'm there to eat. I don't need them to flatter me. If the 1 stars are "the food smelled foul and I saw them mixing leftover soup back into the pot", I know to avoid it. I've seen both of these types a lot. And I also do a quick sort by newest. If all the newest reviews are tourists, I know to steer clear. Tou…
