Twitter vs Yougov



I've never said that polling Twitter is going to be a total replacement for traditional polling far from it but I do think it could be a useful addition is certain circumstances. So I was interested to see how yesterdays Twitter poll compared with the Yougov poll on the London Mayoral election that came out yesterday. I tested the correlation between the two and it came back at 89% quite a bit higher than I was expecting.

> cor(a,b)
