I chose the results of US favourite music genres of 2014.

Rock seemed to be the most popular music genre with a lead of 7% more than the next. The second favourite was oldies with 33% of the population that voted. They found these statistics by looking at how many physical copies were sold, but later in 2016 they looked at the genre of songs people were downloading on their devices and noticed that hip hop or rap has taken the lead. I think the influencing factor is bias because they only checked the physical copies that were being sold at the time, this influenced the 0utcome of this poll because the majority of people that purchase cds are the older generation. They should’ve also analyzed the digital downloads and purchases of music because now a days thats what people use to listen to music.
