Course Description:
The course is designed to introduce our students to some various method of data collection such
as personal interview, postal (mail) questionnaire, telephone interview, results of experiments,
methods of registration and transcription from records (use of secondary data) that they may
likely utilize while collecting data for analysis in the field and the likely sampling and non –
sampling errors they may come across. It also highlights the problems usually encountered and
solutions to some of them.
Course Justification:
The use of data by people all over the world can never be over emphasized. This course will
enable the students to generate data of their choice based on method of data collection being
embarked on and how to provide remedies to the likely errors and problems they may come
across.
