Hi Harin
According to Patton (2001) Qualitative Research is "putting your self into the shoe of the respondent"
Qualitative Research and Evaluation Methods.
In qualitative Research we use
Interview techniques based on open ended questions, observations, through various other participatory techniques ie PRAs. Then reports are generated through the collected information casestudies, themes and than data entry/coding.
However in Quantitative Techniques we normally use Description, Estimation and regression and apply various tests.
One has to be clear and aware of the cost of the survey we are planning to organize.
The Human Resource
Cost of the Survey
and data collected from the survey.
The Researchers in most cases also applies qualitative and quantitative techniques to gather accurate data and reduce the chances of any further errors.
More Simple: The quantitive data collection tells us how many girls are not attending the school but it is the qualitative techniques which cleary elaborate the reasons why girls dont attend schools ie cultural reasons, economic, lack of washrooms through observation, informal meetings, transit walks, word of mouth.
To put it in the most simple terms:Qualitative risk analysis will provide you with the nature of risk and uncertainty you are dealing with, you can label them in a way that in a graph you'll see the treaths such as construction accidents or the absentiesm of workers... while quantitative risk analysis deals with a lot of probabilities and more mathematical tools, such as Monte Carlo simulation and such, in order to have answer like we have a30% chance for a delay in a shipment, or a loss of a supplier..
Qualitative Analysis - is the study of date that can be observed But not measured
Quantitative Analysis - is the study of data that can be measured
