    Use the Chi-square (X^2) method.

    X^2 = ∑ (O-E)^2/E, where O = observed frequency and E = expected frequency.

    ∑ = sum of all the cells.

    E = (column total * row total)/grand total

    df = n - 1, where n = number of cells

    Look up value in X^2 table in the back of your textbook.
