Real-world Application: These designs are common in real-world settings where random assignment is infeasible, such as in education, policy interventions, and organizational changes.

Random assignment is a procedure for assigning participants in an experiment to either the treatment or control groupMultiple choice question.based on the preference of the participant.based on what group the previous participant was assigned to.on the basis of chance, like the flip of a coin.based on a specific pattern picked by the experimenter in advance.

Provide two examples, with an explanation for each, of real world programming design where classes and inheritance might be important.

When evaluating complex interventions a stepped wedge design is sometimes used. In a stepped wedge design randomisation is built into:Group of answer choicesThe implementation phasingThe group levelThe individual levelWithin an individual

You flip a coin. If heads comes up the next person is in the treatment group. If it comes up tails, the next person is assigned to the control group.
