Je hebt niet de juiste calculator gebruikt. De calculator die jij hebt gebruikt toont geen grafische weergave van de verwachte en werkelijke waarden. Dit is niet totaal fout, maar je kan zo geen volledige analyse maken. Je moet de calculator Chi-Squared and McNemar Tests gebruiken.

Een voorbeeld voor deze vergelijking: http://www.freestatistics.org/blog/index.php?v=date/2010/Nov/19/t1290168026hfit7pa1ktue626.htm/

Je analyse is wel goed. Er is namelijk geen samenhang, het is berust op toeval. Daarom hoeven we in dit geval niet meer te kijken naar de grafische output.

Je kon ook gebruik maken van de verfijnde indeling (a,b,c,d) ipv de groffe indeling (Hi, Lo). Ik had het gedaan volgens de groffe indeling.
