This is a common issue and no matter what you set the T-stat on, the outdoor unit will continue to run. It could be caused by bugs, loose wire causing overamperage, or just an old contactor. Unfortunatley, you should call a repair man or if you know someone with some mechanical ability, they could install a new one without problem.

If you have a mercury bulb thermostat it has to be perfectly level or it will not work right. Good luck. Another simple thing you may want to check is be sure your thermostat is level.

If it is a wall unit, then it could be that the compressor was not on but the fan was on (which is OK). If the compressor was on (the coils were ice cold), then the thermostat is the prime suspect. Ensure the knob is mounted correctly while you are at it. While the power is off, turn the thermostat knob through it's full travel and see if you can hear/feel it click on and off at the ambient temperature. No click? Then bad Tstat.
