Observational Study Len: Length of songs in my music folder Artist: Number of letters in artist’s name, length. Size: Size of that file Who: Jean What: music files Where: inside Jean’s computer When: for 3+ years How: Measured by looking up its property Songs are selected randomly from my music folders. I selected 10 of them, and then I measured the length (number of letters) of the artist’s name whom performed that song and also the size of the file in MB.Length of the songs/melody will be in minutes. Possible studies include relationship between length of songs and file size, also relationship between length of song and the length of artist’s names. It would be interesting to see some correlations.
