The group who takes the placebo would be the control group.

How do you identify a quasi experimental design?
Like a true experiment, a quasi-experimental design aims to establish a cause-and-effect relationship between an independent and dependent variable. However, unlike a true experiment, a quasi-experiment does not rely on random assignment. Instead, subjects are assigned to groups based on non-random criteria.

What is a quasigroup?
There are at least two structurally equivalent formal definitions of quasigroup. One defines a quasigroup as a set with one binary operation, and the other, from universal algebra, defines a quasigroup as having three primitive operations.
Is an associative quasigroup empty or a group?
An associative quasigroup is either empty or is a group, since if there is at least one element, the invertibility of the quasigroup binary operation combined with associativity implies the existence of an identity element which then implies the existence of inverse elements, thus satisfying all three requirements of a group.
What are the best books on quasigroup theory?

How do you know if two numbers are the same quasigroup?
In other words: Multiplication and division in either order, one after the other, on the same side by the same element, have no net effect. Hence if (Q, ∗) is a quasigroup according to the first definition, then (Q, ∗, \\, /) is the same quasigroup in the sense of universal algebra.
