A verbal technique for obtaining
data direct from the primary source.
A very systematic method by which
a person enters deeply into the life
Even a stranger and can bring out
needed information and data for the research purpose.

From of strict structural point of view we can identify three types of interview:

B. Unstructured Interview
C. Semi-structured Interview
Types of Interview
![Page 9: Techniques of data collection in qualitative method](https://reader035.vdocuments.site/reader035/viewer/2022062820/58aa9dac1a28ab85678b6693/html5/thumbnails/9.jpg)
The use of a set of pre-determined questions
Highly standardized techniques of recording
The use of fixed, alternative questions
The use of close ended questions
The question order are pre-determined.
Structured Interview
![Page 10: Techniques of data collection in qualitative method](https://reader035.vdocuments.site/reader035/viewer/2022062820/58aa9dac1a28ab85678b6693/html5/thumbnails/10.jpg)

Non-standardize interviewing Do not follow a list of pre-determined question Freedom to talk on whatever events Provide their own definition of the social situation It is very complex process. Use open ended questionnaire
Un-structured Interview
![Page 12: Techniques of data collection in qualitative method](https://reader035.vdocuments.site/reader035/viewer/2022062820/58aa9dac1a28ab85678b6693/html5/thumbnails/12.jpg)

It may not be possible to gather groups of individuals or to visit one-on-one
An asking a small number of general questions
Closed site access Use open ended question
A researcher does not have direct contact with the participant Limited communication to understand the interviewee’s
perceptions of the phenomenon
Telephone Interview

A mode of observation that takes action & observe the consequences of that action. Select a group of subjects Do something to them Observe the effect of what was done It involves 3 components Independent & Dependent
variable, Pre- testing, post-testing, Experimental & control groups
Experiment
![Page 24: Techniques of data collection in qualitative method](https://reader035.vdocuments.site/reader035/viewer/2022062820/58aa9dac1a28ab85678b6693/html5/thumbnails/24.jpg)
Independent variable – cause
Dépendent variable – effect
Example

Independent variable• Depression for
result, relationship• Mixing up with bad
company• Failure in exam• Interest in drugs
becomes habit• Divorced parents• Availability of drugs
Dependent variable
IncreasingDrug addiction among young generation

Pre- testing –measurement before incidentpost-testing- measurement after incidentExampleRate of sharing videos, picture, trolls, statues on social networking sites before & after India vs Bangladesh cricket matchIndicator : Result of the matchIf Bangladesh wins sharing is high before & after the match If Bangladesh losses sharing is less
Pre- testing, post-testing
