Qualitative And Quantitative
Data
Qualitative
Quantitative
Data is in the Numerical form. e.g. number of
years experience of the interviewees, age of the
interviewee, Number of project department handles
etc.
Data that is difficult to measure, count or
express in numerical terms in a sensible fashion.

• It may be possible to record or express
  qualitative data in a numerical form, but that
  does not mean that it is sensible to do so.
• There is a assumption that certain forms of data
  gathering techniques will result in only
  qualitative or quantitative data.
• But this is a fallacy.
• e.g. Questionnaires and Observation

• Quantitative analysis uses numerical methods to
  ascertain the magnitude, amount or size of
  something.
• e.g. Describing population.
• The average person is 5 feet 11 inches tall,
  weighs 180 pounds and is 45 years old.
• Qualitative analysis focuses on nature of
  something and can be represented by themes,
  patterns and stories.
• e.g. Describing population.
• The average person is tall, thin and
  middle-aged.

The First Step in Analyzing Data

• After data gathering sessions are performed,
  there is some initial processing of the data
  normally required before data analysis can begin.
• In different data gathering techniques we have
  different ways in which initial processing of
  data takes place.

Usual Raw Data Qualitative Data Quantitative Data Initial Processing steps
Interviews Audio recordings. Interviewer notes. Video recordings. Responses to open questions. Video pictures. Respondents opinions. Age, Job role, years of experience. Responses to the closed questions. Transcription of recordings. Expansion of notes.

Observation Observers notes. Photographs. Audio and video recordings. Data logs. Think-aloud. Records of behavior. Description of a task as it is undertaken. Copies of informal procedures. Demographics of participants. Time spent on a task. The number of people involved in an activity. Expansion of notes. Transcription of recordings. Synchronization between data recordings.
