a) First of all a basic question. I want to know as to what is the expanded form of TRP. I used to think it was television rating points. But I learned from my boss recently that it is Targeted rating points. He seems to be correct as I have this variable TRP for a Radio advertising data. I wanted to confirm this?
b) Second I would like to know as to what exactly does the phrase targeted rating point mean. How is it different from Global rating point. How are these actually measured? Is there a formula representation for the same.
c) Is there a upper limit for TRP, GRP etc (I was thinking these 2 in terms of percentages so thought that upper limit might be 100 but it doesnt seem to be so)
d) Also is it usual practice to add GRP's (sum up) to get consolidated GRP value?
e) When I want to use TV advertising as a variable in sales/volume modelling is it more correct to use GRP's rather than TRP's. Is there any conversion rate/rule between these 2?
Please guide me.
