What happened? How many people bought this product? What percentage of people considered this brand? Quantitative analysis and research methods often include:. Qualitative and quantitative analyses work best when blended together, a method appropriately called mixed method analysis. It begins with qualitative research and analysis to understand the problem broadly, to define what language we should be using.
Suppose we sell coffee. We might start a research process by asking people what they like about coffee in general. Once we know what questions to ask, we switch to quantitative methods to help us understand how many people have answers to our questions and what those answers are.
Suppose, in our example, people said that the top reason for why they made the coffee choices they made was because of price. Once we understand the numbers and math, we switch back to qualitative to ask why.
Why did we receive the results we did in the quantitative research? Why did people make the choices they made? We would survey or interview a representative, random sample of our quantitatively-analyzed audience to understand why. What did the people who answered this have in common — were they in similar professions? Perhaps they shared a common gender, geography, or ethnicity. Understanding the difference between qualitative and quantitative research helps PR practitioners to explain where they are in the research and analysis process.
But most of the times, physical and chemical analysis techniques are used together with some calculations to determine the exact amount of a component in a given sample. However, there can be many interferences and experimental errors that cause faulty final results.
Quantitative analysis of a sample is very important for several reasons. It gives the details about how much reactant should be used to perform a chemical synthesis reaction to get a certain amount of product, hence the waste of chemicals is reduced atom economy is increased , it can be used to determine the quality of food or any other product by indicating the presence of appropriate amounts of ingredients, it is helpful in determining the purity if a sample, etc.
Qualitative and quantitative analysis in chemistry gives the details of a given sample such as chemical composition and the amounts of different components present in that sample. The difference between qualitative and quantitative analysis in chemistry is that the qualitative analysis in chemistry gives the presence or absence of different chemical components in a sample whereas quantitative analysis in chemistry gives the amount of different chemical components present in a given sample.

A quantitive analysis is an assessment of a certain event or a situation by the means of mathematical or statistical modelling. It uses data measurement and comparison to illustrate a given case with a numerical value.
The quantitive analysis is the backbone of any ecommerce business. A qualitative analysis is an assessment of a certain event or a situation by the means of inquiry or observation. It investigates all the data like interviews and freewritten user feedback forms that can not be counted but must be accounted for. By asking your customers to voice their concerns directly you receive priceless insights into how you can make your selling platform and your product better.
Adopting both — qualitative and quantitative analysis — is incredibly crucial to any business that wants to succeed.
