Quantitative
v/s Qualitative data
Quantitative
data :Quantitative data can
be defined as the data which gives the information in some quantitative form or
in measurable form. We can write the quantitative data in the form of numbers (example
your height, weight, age etc.) and can apply various mathematical and
statistical formulas on it which can help in business decision making at
various levels.This type of data is
closed-ended and is generally easy to analyse. It is important to note that
Quantitative data can be discrete or continuous.
Qualitative data :On the other hand Qualitative data can be defined as the data which gives the information in the form of some descriptions in a language rather than in numbers. This type of data can be observed but cannot be measured (example – color, taste, appearance etc.) but it can also help in taking business decisions under various circumstances.This type of data is open-ended and is more difficult for analysis. It is interesting to know that different analysts can draw different conclusions from the same qualitative data.
Drawbacks and Importance :Quantitative data can provide information about large size of population but does not provide in depth knowledge about a particular entity, so it is backed or supported by qualitative data. Where qualitative data can provide information about a particular thing or issue but is criticized for its unreliability, so it is supported by quantitative data. That is why both qualitative and quantitative type of data is used in any research.
