Interviewer influences on the ratings given "values" questions by farmers

This thesis is an investigation of interviewer bias. The data upon which this thesis is based were collected from two surveys which were conducted in Bradley and White Counties, Tennessee. A survey was conducted at the beginning and one at the termination of the “Trial-Acre Fertilizer Demonstration and Education Experiment.” The terminal survey, it was anticipated, would measure the change that had taken place since the experiment was initiated. A brief background of the “Trial-Acre” program is given before the problem of interviewer bias is approached.
