To this end, the two Tables below explain how confidence limit calculations can be applied to the findings of the ROI TGI. Since these calculations rest on an awareness of the sample sizes and penetrations of given results, this information is included below primarily for the benefit of direct-users of the TGI database. For non-subscribers of the TGI, detailed information on the particular levels of confidence attaching to any of this report’s findings can be provided on request. The authors of this report have nonetheless focussed on finding which are typically of a significant nature. For interested in further detailed information on this matter: 1 allows the calculation of 95% confidence limits for percentage penetration statistics in TGI. To use this table, look up the percentage to be tested in the appropriate column, and the sample figure in the row. The intersection of the row and column gives the confidence limit figure required. For example, if a magazine has an un-weighted sample of 200 readers, and 30% of these have own a Nokia mobile phone, Table 1 shows that the 95% confidence limits for this percentage are + 7.3%. So, there is only a 1 in 20 chance that the true population figure is outside the range 37.3% to 22.7% (i.e. 30% - 7.3% to 30% + 7.3%). If confidence limits for a 25% penetration are required, an estimate can be taken midway between the 20% and 30% columns.
