Qualitative analysis and quantitative analysis are two basic methods of receiving and interpreting data in research. These methods can be used separately or even together. However, they have some errors individually, and these errors can be covered up if they are used concurrently to give a quality result.
Qualitative analysis is frequently used when you carry out research that has to do with numeric values, after which data is generated, classified, and calculated using some statistical methods. Qualitative analysis is said to be more objective in approach. Conversely, when data cannot be quantified, then the qualitative analysis is put into use.
The kind of data usually calculated with qualitative analysis is about the insights and understanding of the attributes and properties of the objects involved. Qualitative analysis is known to be subjective, exploratory, non-statistical, and descriptive in nature. Data are collected in unrepresentative and small samples when it comes to qualitative analysis; whereas, data are collected in representative and large samples.
