Descriptive research or statistical research provides data about the population or universe being studied. But it can only describe the “who, what, when, where and how” of a situation, not what caused it. Therefore, descriptive research is used when the objective is to provide a systematic description that is as factual and accurate as possible which is further classified into two types:
- Longitudinal study – A study that involves repeated observations of the same variables over long periods of time often many decades.
Examples:- GDP, Unemployment rate, population ,etc.
- Cross sectional study- Also known as cross-sectional analyses, which involves data collection from a population, or a representative subset, at one specific point in time.
Example:- Television rating point (TRP)
How RFID is used in Wal-Mart?
Wal-Mart, the world largest retailer, is also a leader in pioneering technologies to achieve operational efficiencies that ultimately bring saving for its customers. Recently it started using RFID for its clothing instead of barcode. RFID transfers data stored on tags of clothes (like its price, size) which facilitates reading and identification, along with this it also helps in tracking people. But the use of this technology has lead to major issues like, RFID can be used for tracking purpose which has lead to privacy concerns among its customers. Here’s the video showing this
Other than Wal-Mart, Harley Davidson and Toyota also use RFID to track the parts of motorcycle and automobiles.
How shows or channels are rated in India?
Television Rating Points – TRP is the criterion that indicates the popularity of a channel or programme and this data is very useful for the advertisers. Presently, INTAM (Indian Television Audience Measurement) is the only electronic rating agency functioning in India. INTAM uses two methodologies for calculating TRP. First is frequency monitoring, in which ‘people meters’ are installed in sample homes and these electronic gadgets continuously record data about the channel watched by the family members. ‘People meter’ is costly equipment, which is imported from abroad. It reads the frequencies of channels, which are later, decoded into the name of the channels and the agency prepares a national data on the basis of its sample homes readings. But there is a drawback in the technique, as cable operators frequently change the frequencies of the different channels before sending signals to the homes. It may be very misleading to read a channel according to a particular frequency even if the down linking frequency is same all over India.
Second technique is more reliable and relatively new to India. In picture matching technique people meter continuously records a small portion of the picture that is being watched on that particular television set. Along with this agency also records all the channels’ data in the form of small picture portion. Data collected from the sample homes is later on matched with the main data bank to interpret the channel name. And this way national rating is produced.
A.C Nielsen- The Nielsen Cross-Platform Homes Panel is the only single source measurement panel that delivers analytics to maximize value of cross platform strategies. Nielsen measures GRP, reach & frequency to understand TV & Internet behavior to enhance online campaigns and improve cross platform ROI. The methodology provides vital insights and helps clients understand how consumers engage with media across all platforms they us
