Ms. Cheritha, the advertising manager for Chemical Topics magazine, is responsible for selling advertising space. The magazine is distributed solely by subscription to engineers and technical professionals in the chemical processing industry. Major advertisers are companies that produce chemical processing equipment.
Ms. Cheritha wants to collect more detailed data on the readership to provide more value to potential advertisers. She has circulation figures but believes they understate the exposure of ads since issues are likely shared with others in a subscriber's firm. She wants to determine the size of this "secondary audience" and gather more reader details like education, job role, and hierarchy level.
