Right, i've got a chi squared test to do, but i've only been given the observed values, and have no idea how to work out the expected values, does anyone know how to get the expected values?

    I still dont get it lol (stats is not a strong point of mines)
    the data we've been given is like Child (1-25) Blood Group, Pathology (severe or uncomplicated) and Rosette Frequncy (which is a percentage)

    Lol this is due at half 4 today so all help much appreciated

    Also

    the actual question is

    "calculate the 2 statistic and report a p-value in order to test the hypothesis that those children with blood group O are less likely to have severe malaria than those of blood group A. Do the same test comparing blood groups O and B and blood groups O and AB."
