Determine the populations being investigated
Nielsen ratings are audience measurement systems developed by Nielsen Media Research in an effort to determine the audience size and composition of television programming in the United States. These ratings are determined by way of viewer diaries and Set Meters which are devices connected to televisions in selected homes. The most commonly cited Nielsen results are reported in two measurements: ratings points and share. For example, Nielsen may report a show as receiving a 9.2/15 during its broadcast, meaning that on average 9.2 percent (rating points) of all television-equipped households were tuned in to that program at any given moment, while 15 percent (share) of households watching TV were tuned into the program during this time slot. Describe the two different populations being investigated with these two rating systems.
