    Calculation of standard deviation of percentages of different base sizes

    Hi,

    I'm looking to calculate the standard deviation of %'s. If they were the same base, i would simply calculate the standard deviation as normal. However, as the base sizes are different for the %, how do i go about calculating the standard deviation?

    Thanks,
