Selecting a method of data collection

Differences in methods of data collection in quantitative and

qualitative research• Most methods of data collection can be used in both qualitative

and quantitative research.

• The distinction is mainly due to the restrictions imposed on flexibility, structure, sequential order, depth and freedom that a researcher has in their use during the research process.

• Quantitative methods favour these restrictions whereas qualitative ones advocate against them.

The classification of a method into the quantitative or qualitative category depends upon your answers to the following questions

• How was the information collected? Was it through a structured or unstructured/flexbile format of data collection?• Were questions or issues discussed during data collection

predetermined or developed during data collection?• How was the information you gathered recorded? Was it in

descriptive, narrative, quantitative form or on a scale?• How was the information analysed? Was it descriptive or numerical

analysis?

Example

• If an observation is recorded in a narrative or descriptive format, it becomes qualitative information, but if it is recorded in categorical form or on a scale, it will be classified as quantitative information.

Major approaches to information gathering

A)primary data (observation>particant/non-participant)(interviewing> structured/ unstructured)(questionnaire> mailed questionnaire/ collective questionnaire)B) Secondary sourcesDocuments (govt publication, earlier research, Personal records, service records)

Examples of primary sources include• Determining the job satisfaction of the employees of an organization• Ascertaining the health needs of a communityExamples of secondary sources• The use of organization’s records to ascertain its activities• The collection of data from sources such as articles, journal,

magazines, and books

Collecting data using primary sources

• Observation• There are two conditions in which conversation can be made:A. Natural. B. ControlledIt is one way to collect primary data by watching and listening to an interaction or phenomenon as it takes place.Examples: when you want to learn about the interaction in a group. OrTo study the behavior or personality traits of an individual

Types of observation

1. Participant observation2. Non-participant observation

Participant observation

It is when you, as a researcher, participate in the activities of the group being observed in the same manner as its members, with or without their knowing that they are being observedFor example, you might want to examine the reactions of the general population towards people in wheelchairs. You can study their reactions by sitting in a wheelchair yourself. Or you might want to study the life of prisoners and pretend to be a prisoner in order to do this.

Non-participant observation

• It is when you, as a researcher, do not get involved in the activities of the group but remain a passive observer, watching and listening to its activities and drawing conclusion from this.

For example, you might want to study the functions carried out by nurses in a hospital. As an observer, you could watch, follow and record the activities as they are performed. After making a number of observations, conclusions, could be drawn about the functions nurses carry out in the hospital.

Recording conversation

• Narrative recording• Using scales• Categorical recording• Recording on electronic devices.

The interview

• An interview involves an interviewer reading questions to respondents and recording their answers (Monette et al 1983)

• It is any person to person interaction, either face to face or otherwise, between two or more individuals with a specific purpose in mind.

Types of interviews

• Unstructured interviewsIt provides complete freedom in term of content and structure.You are free to order the questions in whatever sequence you wishAlso, you are free in the term of word that you are using.You may formulate questions and raise issues during the interview.In quantitative research, you develop response categories from responses which are then coded and quantifiedIn qualitative research, the responses are used as descriptors.

Types of interview

• Structured interviewsThe researcher asks a predetermined set of questions, using the same wording and order of questions as specific in the interview schedule.

The questionnaire

It is a written list of questions, the answers to which are recorded by respondents .

Questions should be clear and easy to understandIt should be developed in an interactive style

Ways of administering a questionnaire

• The mailed questionnaire

• Collective administration

• Administration in a public place

Content of the covering letter

• Introduce you and the institution you are representing• Describe in two or three sentences the main objectives of the study• Explain the relevance of the st

Collecting data using secondary sources

• Government or semi-government publication

• Earlier research

• Personal records

• Mass media

Problems with using data from secondary sources

• Validity and reliability • Personal bias• Availability of data• Format
