Arduino PWM Outputoutput cannot drive MOSFET 0-12V

On an ArudinoArduino Uno, the PWM pin 3 is connected to the gate pin of an N-channel MOSFET STP16NF06L. The source pin is connected to ground of a 12V12 V power supply and drain pin connected to a multimeter. The other end of the multimeter is connected to the positive terminal of the power supply.

Question: When Arduino varies its PWM output from 0 to 255, the multimeter reading goes from 11.50V50 V to 12.10V10 V. Why isntisn't it 0 to 12V12 V?

When the FET gate is connected to the ArudinoArduino pin that outputs either 0V0 V or 5V5 V, the multimeter reading is as expected at 0V0 V and 12V12 V respectively.
