Data collection methods
Data collection methods are divided into primary and secondary collection methods. Under primary, we have:
- Use of interviews
It is a method of data collection that involves oral questioning of a certain population whether individuals or in groups. Response from the interviewee regarding a certain question are recorded either at the time of interview or are tape recorded for later recording and analysis. Questions may be fixed or flexible depending on the target group (Kothari, 2008).
- Use of questionnaires
Questionnaires are structured questions given to respondents who are expected to answer them in written form and then give them back to data collector. The questionnaires can be sent through post, email or faxed to a respondent, they can also be hand derived.
Observation is a data collection method where the researcher uses his eyes and participates in certain activities as he collects data. Observation may be open where the researcher takes data from the occurrence of certain activities or may be closed where the observer takes data from a limited number of people (Axinn & Lisa, 2006).
- Focus groups
Focus groups are groups composed of a population that has the required information. They are collected together and the team leader who is usually the researcher asks relevant questions that lead to data collection in his area of interest. The team leader gives members of a group the chance to discus and gives their views regarding a certain phenomenon.
Secondary data collection
Other than primary data collection method, there is secondary data collection method that involves taking data from literature reviews of related material. The researcher does not go to the field to collect data but reviews data that already exists may be in books, documentaries, internet and media (Patton, 2002).
Importance of examining collected data
After data has been collected, it needs to be examined for quality and reliability. Consistency of data is important for data analysis thus it is important to examine and test the data collected. Extremes data are disregarded to ensure that data used for analysis can be generalized when making final inferences.
