How to classify Statistical Units in One - Minute
HTML-код
- Опубликовано: 9 июл 2023
- In statistics, a statistical unit is one member of a set of entities being studied. It is the main source for the mathematical abstraction of a “random variable”. Common examples of a unit would be a single person, animal, plant, manufactured item, or country that belongs to a larger collection of such entities being studied. Units are often referred to as being either experimental units, sampling units or units of observation1.
For example, in an experiment on educational methods, methods may be applied to classrooms of students. This would make the classroom as the experimental unit. Measurements of progress may be obtained from individual students, as observational units. But the treatment (teaching method) being applied to the class would not be applied independently to the individual students. Hence the student could not be regarded as the experimental unit. The class, or the teacher by method combination if the teacher had multiple classes, would be the appropriate experimental unit1.

For a study on anaemia in pregnancy:
1. Statistical units/Unit of collection = pregnant women
2. Unit of enumeration = pregnant women
3. Simple Unit of recording = PCV( in %)
4. Compound unit of recording = PCV/Hb level/ MCV/MCH/MCHC
Complex unit of recording = FBC comprising the full complement of the panel.
For unit of analysis:
1. Rate = number of pregnant women with anaemia per 100, 000 women of reproductive age.
2. Ratio = number of pregnant women with anaemia per 100,000 live births
3. Percentage = number of pregnant women with anaemia per 100 pregnant women.
Coefficient could be relationship of parity or interpregnancy interval on anaemia incidence or severity
Much appreciated sir.
