There are many data collection methods, but how you ultimately choose to collect data will depend on the design of your study. Below are some common methods of collecting dissertation data and the types of projects for which these methods are most appropriate.
Data Collection Methods Regardless of the topic of your dissertation or thesis, it is highly likely that at some point you will need to collect data.
Below are some common data collection methods. Remember, you will want to collect data in a way that fits your research design and questions. Self-Report Self-report is a type of research design in which participants give their responses to a given set of questions.
The most common types of self-report are interviews or questionnaires. One major limitation of self-report versus other data collection methods is that accuracy of responses cannot be determined, and there are many circumstances in which participants are likely to lie.
Observation Observation is a method of collecting data in which members of research teams observe and record behaviors.
Data collected during observation are explicit and quantifiable. However, observation has many limitations. First, researchers who use observation can only observe behaviors; therefore, observation cannot be used to collect data about attitudes, beliefs, thoughts, covert behaviors, etc.
Another limitation of observation is that it is a known fact that being observed changes behavior. Observation can be either formal e. These types of data are useful because they are quantifiable and accurate.
However, these types of data are sometimes used as secondary measures of latent constructs, which may not always be accurate. For example, someone with a high heart rate may be perceived as being anxious, but it is possible that that person just walked up a flight of stairs.
Interviews Interviews are one of the data collection methods for qualitative research. Interviews consist of meeting with participants one on one and asking them open-ended questions. Interviews can be structured or semi-structured.
In a structured interview, the researcher has a predetermined set of questions to ask and does not deviate from those questions. In a semi-structured interview, the researcher will have prepared questions but has the freedom to ask additional follow up questions as he or she sees fit.
Focus Groups Focus groups are another example of data collection methods of a qualitative study. Using focus groups to collect data is similar to using interviews because focus groups allow participants to freely answer questions; however, as implied by the name, focus groups consist of multiple people all being asked questions at the same time.4 Data Collection Methods: Semi-Structured Interviews and Focus Groups example of this is the census survey, which has historically asked respondents to categorize themselves by race categories that have not always fit the self-identity of the respondents.
Corbin and Straus define theoretical sampling as “ a method of data collection based on concepts/themes derived from data” (, p. ). Theoretical sampling is not something you can determine up front before you begin to collect data. There must always be data that should be collected, organized, analyzed, and interpreted in any research undertaking.
No research activity can be succeeded without necessary data so the data collection is important phase of the research process. As it is indicated in the title, this chapter includes the research methodology of the dissertation.
In more details, in this part the author outlines the research strategy, the research method, the research approach, the methods of data collection. There must always be data that should be collected, organized, analyzed, and interpreted in any research undertaking.
No research activity can be succeeded without necessary data so the data collection is important phase of the research process. CHAPTER 7 DATA COLLECTING METHODOLOGY data collection. When following this method of data collecting, it is essential to as for example those in chapters 2 and 3 of this thesis.
The secondary data for the thesis has been obtained by studying manuals, magazines.
