How Quantitative and Qualitative analysis helps in Data Analytics?

Look at Data long enough and you will find all sorts of insights, patterns, and relationships some more obvious than others. Data Analytics is the systematic effort to uncover it all-to find information about the information. The goal of Data Analytics is to utilize this insight to help a person or computer program make an objective decision that will most likely yield the desired outcome. It all starts with an analyst who must first decide what data is most relevant to the business objective.

What data should he/she collect to answer a given business question? Next, the analyst must prepare it for analysis by eliminating duplicate data and making sure the remaining data is properly formatted so that the analytics software can work with it. Once this issue of data quality is addressed, the actual analytics begin.

What comprises Quantitative Data?

Quantitative data is interpreted as the value of data in the structure of counts or numbers where each data-set has a different numerical value correlated with it. This data is any quantifiable evidence that can be utilized for mathematical calculations and statistical analysis, such that real-life decisions can be made established on these mathematical derivations. Quantitative data is utilized to resolve questions such as “How many?”, “How often?”, “How much?”. This data can be assessed and can also be conveniently analyzed utilizing mathematical procedures.

For instance, there are quantities conforming to various parameters, for instance, “How much did that laptop cost?” is a question that will collect quantitative data. There are values attributed to most measuring parameters such as pounds or kilograms for weight, dollars for cost, etc.

Quantitative Data: Collection Methods

There are two central Quantitative Data Collection Methods:

  • Surveys: Traditionally, surveys were administered utilizing paper-based procedures and have deliberately unfolded into online fora. Closed-ended questions constitute a crucial portion of these surveys as they are more beneficial in compiling quantitative data. The survey includes answer options that they believe are the most reasonable for a specific question. Surveys are vital in amassing acknowledgment from an audience which is enormous than the formal size.
  • One-on-one Interviews: This quantitative data collection method was also traditionally performed face-to-face but has changed positions to telephonic and online outlets. Interviews propose a marketer the alternative to compile comprehensive data from the participants. Quantitative interviews are enormously structured and influence a pivotal function in obtaining evidence.

What constitutes Qualitative Data?

Qualitative data is interpreted as the data that approximates and characterizes. Qualitative data can be examined and documented. This data type is non-numerical in essence. This category of data is received through procedures of statements, one-to-one conferences, administering focus groups, and related techniques.

Qualitative Data Collection Methods

1.One-to-One Interviews: It is one of the commonly utilized data collection devices for qualitative exploration, primarily because of its subjective strategy. The interviewer or the researcher compiles data immediately from the interviewee on a one-to-one basis. The interview may be informal and unstructured – conversational. Mostly the open-ended questions are asked spontaneously, with the interviewer allowing the flow of the interview to dictate the questions be inquired.

2. Focus groups: This is done in a group discussion environment. The group is limited to 6-10 people, and a mediator is appointed to mediate the continuous discussion.

To understand in a detailed manner about this arena you can enroll in data analytics online training to receive hands-on experience of the same.

How Qualitative and Quantitative Data Helps in Analysis?

Now that we have enlisted the basics of qualitative and quantitative data, it’s time to review which category is beneficial for data analysis and why.

Qualitative data is commonly contemplated as unstructured data or semi-structured. This type of data is loosely formatted with very limited structure. Due to this, qualitative data cannot be assembled and assessed using traditional procedures. Understanding of the qualitative data can be time-consuming and expensive, although there are some procedures of “structuring” this data.

The growth of No SQL databases has made the exhibition and storing of qualitative data much more adaptable, but it's still an upward spurt before being eligible to stifle this data effectively.

Quantitative data is usually perceived as structured data. This kind of data is formatted in a means so it can be instantly composed and searchable within relational databases. Since qualitative data and structured data go hand-in-hand, this kind of data is usually desired for data analysis.

Bottom Line: Data analysis is presumably the most significant element of exploration. The unstable examination generates faulty outcomes that not only impede the genuineness of the study but also make the outcomes unusable. It’s imperative to select your data analysis techniques carefully to guarantee that your discoveries are insightful and actionable. KVCH offers an extensive data analytics online course delivered by trained specialists.
