Case 16.1 Who's Fishing? Washington

Case 16.1 Who's Fishing?
Washington Times columnist Gene Mueller writes about fishing and other outdoor sporting activi-ties.'3 Mueller commented recently that although interest groups express concerns about the impact of saltwater fishers on the fish population, no one really knows how many people fish for recreation or how many fish they catch. This situation would challenge mar-keters interested in the population of anglers. How could a researcher get an accurate sample? One idea would be to contact residents of coastal counties using random-digit dialing. This sampling frame would include many, if not all, of the people who fish in the ocean, but it would also include many people who do not fish—or who fish for business rather than recre-ation. A regional agency seeking to gather statistics on anglers, the Atlantic Coastal Cooperative Statistics Program, prefers to develop a sampling frame more related to people who fish.
Another idea would be to use state fishing license records. Privacy would be a drawback, however. Some people might not want their records shared, and they might withhold phone numbers. Further complicating this issue for Atlantic fishing is that most states in the Northeast do not require a license for saltwater fishing. Also exempt in some states are people who fish from the shore and from piers. A political action group called the Recreational Fishing Alliance suggests that charter fishing businesses collect data.

Questions
1. Imagine that an agency or business has asked for help in gather-ing data about the number of sports anglers who fish off the coast of Georgia. What advice would you give about sampling? What method or combination of methods would generate the best results?
2. What other criteria besides accuracy would you expect to con-sider? What sampling methods could help you meet those criteria?

Kasus 16.1 yang adalah Memancing? Washington Times kolumnis gen Mueller menulis tentang memancing dan Kamea olahraga lain kolam-ikatan.'3 Mueller baru-baru ini berkomentar bahwa walaupun kelompok-kelompok kepentingan mengungkapkan kekhawatiran tentang dampak dari air asin nelayan pada populasi ikan, tidak ada yang benar-benar tahu berapa banyak orang ikan untuk rekreasi atau bagaimana banyak ikan yang mereka menangkap. Situasi ini akan menantang mar-keters tertarik pada populasi pemancing. Bagaimana bisa seorang peneliti mendapatkan sampel akurat? Satu ide akan menghubungi warga pesisir County menggunakan panggilan acak-digit. Frame sampling ini akan mencakup banyak, jika tidak semua, dari orang-orang yang ikan di laut, tapi itu juga akan mencakup banyak orang yang tidak ikan — atau yang ikan untuk bisnis daripada recre-ASI. Agen daerah yang berusaha untuk mengumpulkan statistik tentang pemancing, Atlantic pesisir koperasi Statistik Program, lebih suka untuk mengembangkan kerangka sampling yang lain yang berkaitan dengan orang-orang yang ikan. Gagasan lain akan menggunakan catatan lisensi negara memancing. Privasi akan kekurangan, namun. Beberapa orang mungkin tidak ingin berbagi catatan mereka, dan mereka mungkin menahan nomor telepon. Yang lebih rumit masalah ini untuk Atlantic Memancing adalah bahwa sebagian besar negara di timur laut tidak memerlukan lisensi untuk memancing air asin. Juga dibebaskan di beberapa negara adalah orang yang ikan dari pantai dan dermaga. Sebuah kelompok aksi politik yang disebut Aliansi Memancing rekreasi menunjukkan bahwa Piagam Memancing bisnis mengumpulkan data. Questions 1.
