A method converts online data into quantitative measures of reach and frequency. Gross Rating Points, Targeted Rating Points, frequency, targeted cost per thousand, and average advertising cost per person may be determined using data to measure the percent of non-country respondents receiving and gathering incidence of age, sex, income and other variables used to define target audience. Data may be merged to calculate GRP delivery by geographic region for the purpose of integrating online advertising into a marketing mix analysis. Over-samples may be used within events to measure different respondents' pre and post the event to measure incrementality of event. The total event attendance may be estimated and used to weight the over-sample back into the overall sample. Discrete media groupings may be used to identify the dilution of effects inherent in scaling thereby increasing the accuracy of projected results.
