    This question is difficult to answer without the use of figures, so look here:

    Pay particular attention to the polarity of the hall voltage and how you connect the voltmeter.

    In particular, the polarity of the Hall Voltage depends on the sign of the majority charge carriers. eg: p-type => holes are majority charge carriers => positive charge.
