QUESTIONNAIRE METHOD
• A questionnaire is a research instrument
consisting of a series of questions and other
prompts for the purpose of
gathering information from respondents.
 Practical
 Large amounts of information can be collected from a large
number of people in a short period of time and in a
relatively cost effective way
 Can be carried out by the researcher or by any number of
people with limited affect to its validity and reliability
 The results of the questionnaires can usually be quickly
and easily quantified by either a researcher or through the
use of a software package
 Can be analysed more 'scientifically' and objectively than
other forms of research
 When data has been quantified, it can be used to compare
and contrast other research and may be used to measure
change
 Positivists believe that quantitative data can be used to
create new theories and / or test existing hypotheses
•
Is argued to be inadequate to understand some
forms
of information - i.e. changes of emotions, behaviour,
feelings etc.
•Phenomenologists state that quantitative research is
simply an artificial creation by the researcher, as it is
asking only a limited amount of information without
explanation
•Lacks validity
•There is no way to tell how truthful a respondent is
being
•There is no way of telling how much thought a
respondent has put in
SCHEDULE METHOD
 Schedule is the tool or instrument used
to collect data from the respondents
while interview is conducted. Schedule
contains questions, statements (on
which opinions are elicited) and blank
spaces/tables for filling up the
respondents.
 The schedule is presented by the
interviewer. The questions are asked
and the answers are noted down by
him. The list of questions is a more
formal document, it need not be
attractive.
 Questionnaire: It is a set of questions
typed or printed and sent to the
respondents through mail are post
which should be returned back after
answering.

