- The use of statistics can help in the whole process of outcomes based teaching and learning. If you wishes to teach about abstract ideas such as PATROITIC LOVE, RELIGIOUS FANATICISM, and POLITICAL PATRONAGE, it is good to know that statistics can help clarify such concepts. Ideas that you want to communicate are actually idea-images, not the physical or social realities themselves which are the subject of learning. This is the same as saying you don’t communicate external ideas, rather concepts about external realities.
- COLOR OF DRESS or HEAT OF FIRE Requires indirect observation. IDEA OF FEMALE – SIGN OF GENDER IQ (Intelligent Quotient)
- Visiting a home for the aged can be an indicator of human compassion. Then we can assign numbers, as indicators of levels or intensity of compassion to individuals, possibly judged by the way of the number of visits they made: ex 5 for Hermione 4 for Ginny 3 for Luna 2 for Ron 1 for Harry 2.
