- Title
Predetermining the Necessary Size of a Sample in Marketing Studies.
- Authors
Vernon, Raymond
- Abstract
The article discusses predetermining sample sizes in marketing studies. Market analysts say sample size is critical in accurately measuring market characteristics. Analysts use statistical methods including the arithmetic mean, or arithmetic average and the percentage proportion of a total. These methods present problems of "true" measurement for analysts. A method of obtaining an arithmetic average of a desired accuracy is presented. The equation incorporates the desired number of cases to ensure accuracy, the accuracy necessary for the arithmetic average, and the range of data in which all data will fall.
