<span>I don't think it makes sense to speak of "long-term" abortion (that would mean a very slow abortion maybe?) and of inclusive abortion. A spontaneous abotion is a name that can be used for a miscarriage, that is when a woman's body rejects the baby. If a woman wants to force this abortion, this is called an induced abortion, induced for example by medicine.</span>
Stratified random sampling is a design that involves dividing a group into smaller division or strata to get a defined result, this division is based on character or shared attitude. This design is also known as proportional random sampling.
