Electrical discrimination is to do with selecting the correct protection in the fault path of an electrical circuit.
To illustrate, if you have a machine at the end of an electircal circuit and that is protected by a 13A fuse lets say, and then you have a 20A circuit breaker protecting that at the consumer unit (fuse board), and then the main switch on the consumer unit is a 10A circuit breaker, then every time the machine uses more than 10A of power the main switch will trip and disconnect everything connected to it, that is where discrimination is not achieved.
Basically it is where the circuit protection closest to the macine is smaller and it gets bigger as it goes boack to the source, then discimination is achieved.
I hope that helps. If not then it probably need a drawing to help answer.

What is the Q factor in electrical and electronics engineering?
Q is the general idea of component quality, mainly in AC circuits. It is equal to reactance divided by resistance. The Q factor of an entire circuit can also be computed the same way. In general, adding resistance decreases the circuit or component Q. The "Q" factor is a empirical number to imply the acuteness of a circuit to discriminate surrounding influences and act on the Q of the circuit. The higher the Q THE SHARPER THE RESPONSE.
The power factor of a purely resistive circuit will be?
The power factor of a purely resistive circuit is 1.0.
What is power factor of resistor?
A resistor doesn't have a power factor. However, if a circuit is pure resistance in nature the power factor will be one when a voltage is applied and a current flows in the circuit. The power factor is a measure of the relative phases of the current and voltage in a circuit.
What is a transformer and what principle is used in transformer?
A transformer is a static device which converts electrical energy from one circuit to another circuit without changing frequency, power, power factor. It works on the principle of faradays laws of electro magnetic induction.

What are the differences between resistive load and inductive load in terms of their impact on an electrical circuit?
A resistive load directly resists the flow of current in an electrical circuit, causing a voltage drop. An inductive load, on the other hand, creates a magnetic field that can store energy and cause a delay in current flow. This can lead to power factor issues and voltage spikes in the circuit.
