Make-up question for Aug 27, 2010

X is a form of rating system developed in the 1950s, and is the primary method of measurement in the field for which it was designed. Data for the ratings can be gathered either by getting the "consumer" to self-record, or by using a meter that automatically records data, with the added advantage of increased granularity. These ratings are used to decide which "products" are more in demand, and also to appropriately charge for advertising. Calculation of X involves sampling of a subset of people, and is therefore prone to sampling bias. Also, people's behaviour might change due to awareness of being in the sample population. Another criticism is that X does not reflect "total consumption". More recently, newer modes of "consumption" have rendered the old system more inaccurate. A plan has since been announced to revamp the entire methodology.

Identify X. If not the name, atleast identify what is being described.

Nielsen ratings.

In relation, I remember this vignette from a "This American Life" episode where this person actually thought "Nielsen families" were some privileged clan whose opinions were considered indicative!

The answer is Nielson Ratings, developed to determine what TV audiences are watching. Since internet viewership of TV shows is increasing, Nielson ratings do not capture actual viewership numbers for programs.

Congrats to Angelus, Rahul, Nikhil and Anangrawat for the correct answer.
