* - difference between the category mean and the mean of the No LIPFM category is statistically
different from zero using a two-sided unpaired t-test at the 95 percent level of confidence.
Numbers in parentheses are the number of observations in the category
Ratings analyzed are the average quarter hour rating for persons aged 12+ in the Monday - Sunday
6am - 12m daypart in the Fall ratings period.
Observations are for ratings of stations in the Arbitron Metros the stations are home to as well as
Metros where the stations are physically located.
32. We continue our analysis of the effect of the presence of LPFM stations on fidl-service
commercial FM stations by station format with an examination of the differences in ratings. We compare
the change in ratings of stations of a particular format that had an increase in the presence of LPFM
stations to similarly formatted full-service commercial FM stations that did not have a change in the
presence of LPFM stations. Because stations may change formats during the period in question, we also
limit our analysis to stations that maintained the same program format in 2005 and 2007. Table 8
presents these comparisons. The table presents no significant statistical evidence that the ratings of full-
service commercial FM stations are influenced by the presence of IPFM stations. We do note that the
number of observations available to test hypotheses in this instance is generally quite low. This limits our
ability to make statistical inferences at any reasonable level of confidence.83
