Ad break is an average of spots within the break. Earlier system reported single TVR for all spots in a minute. In BARC, spots within a minute have different rating. Our observation is that this is the case only if start time of the spot is in previous clock minute and end time is the consecutive minute, how is the spot TVR arrived at for such a spot?
If the ad duration is 40seconds and 10 seconds happen in minute 1 and 30 seconds in minute 2, the spot TVR would be a weighted average of TVR of the two minutes, i.e spot TVR = ((10*minute 1 TVR)+(30*minute 2 TVR))/40
More clarity on the differences between weekly and daily weights elucidated with examples
BARC is going ahead with only daily weights across all their modules. Daily weights is more representative of daily information on viewership vis-à-vis weekly weights where incidence of 'no data' reporting by BARC meter also had to be considered and thus not being a true representation of what's happening at the viewer end.
Will RF module use daily weight or mid-period? Universe reported will be basis which day of the campaign?
RF module uses daily weights. Reach reported will vary as the period of the campaign increases, i.e. week 1 campaign reach taken in week 2 would be different from what's finally getting reported as week 1 reach at the end of the campaign because of the daily moving weights.
So, how is course correction to happen? Will pre and post evaluation have the same weighting method used? What's the method?
Yes, pre & post RF are basis daily weights.
If both are basis daily weights how will duplication in reach be contained?
Duplication in reach is getting contained with changing weights during the campaign.
What happens, when data release day (Thursday) is a Public Holiday
If data release day is a Public Holiday then it will be released on the next working day at 11am.
What is the rural definition taken for data?
The definition of Urban and Rural is as per Census of India 2011 which is as follows :
Urban : Constituents of Urban area are Statutory Towns, Census Towns and Outgrowths.
Statutory Town: All places with a municipality, corporation, cantonment board or notified town area committee etc.
Census Town: Places that satisfy the following criteria are termed as Census Towns. (a) A minimum population of 5,000 (b) At least 75% of the male main working population engaged in non-agricultural pursuits (c) A density of population of at least 400 per sq.km.
Out Growth: Out Growth should be a viable unit such as a village or part of a village contiguous to a statutory town and possess the urban features in terms of infrastructure and amenities such as pucca roads, electricity, taps, drainage system, education institutions, post offices, medical facilities, banks, etc. Examples of Out Growths are Railway colonies, University campuses, Port areas, that may come up near a city or statutory towns outside its statutory limits but within the revenue limit of a village or villages contiguous to the town or city.
Rural : All area other than Urban are Rural. The basic unit for rural areas is the revenue village.
There could be an Urban area with 10000 or 5000 population and a rural area which may have 50k population
We cover all pop-strata units classified as Urban and all pop strata units classified as Rural
We will be reporting our pop strata coverage (Urban and Rural) as under
10-75 lakh towns
<10 lakh urban areas
(All 4 pop strata may not be available for all states/state groups)
