Temperature coefficient 
NTC - negative resistance coefficient, resistance decreases with temperature
PTC - positive resistance coefficient, resistance increases with temperature

Temperature coefficient: 50ppm/°C
Meaning that the change in value due to a temperature change of 1°C will not be more than 50Ω for every 1MΩ of the resistor's value (or 0.05Ω for every 1KΩ of its value).


Temperature coefficient: 2750K ppm/°C
Meaning that the change in value due to a temperature change of 1°C will not be more than 2750Ω for every 1MΩ of the resistor's value (or 2.75Ω for every 1KΩ of its value).
