“Where there is data smoke, there is business fire.”- Thomas Redman.
This analogy rightly describes the focus and the emphasis that the organizations are placing on Data analytics to continue their “business fire”. But what does this mean? This means that data is the fuel that can get a business on track or at least provide actionable information that can help strategize current campaigns, easily organize the launch of new products, or try out different experiments. But do you know how much data is created per day? Hold your breath because the figure will shock you.
Data is a life-saver, and data science is about dealing with raw or structured data. We are entering into a world of digitization where every component is driven by data. This has led to increasing demand for data science courses among the aspirants. Our online certification training programs let you master the basic and advanced concepts with real-life industry cases that will enhance your candidature in the job market.
So, let us start to navigate on data and the types of data through this blog. Just scroll down your eyes and enhance your intuition.
Since the inception of computers, people have referred to data as a piece of information that is either stored or transmitted. But does it end here? No. Data encompasses the systematic recording of numerical information derived from digital interactions as facts and figures. The continuous data flow has helped millions of organizations all over the world to attain growth. So, in simple terms, data is a huge record of information divided into various categories to get different types of data.
Information on the other hand is organized data that is used to make decisions and is of value to the user. When this data is of so much importance, it becomes inevitable to store this data properly and safely. We use data science to ease our work with data. Data science is defined as a field that combines mathematical knowledge, programming skills, expertise in the field, and knowledge from structured and unstructured data and then applied to a broad range of uses and domains.
Data helps in visualizing relationships in an organization. Data allows organizations to communicate effectively in different departments or systems. Let us see how data serves its importance in an organization-

While dealing with datasets, categories of data play a vital role. It determines which strategy should work best for a particular set to bear effective results or which type of analysis should be done for better output. Let’s quickly discover what are the types of data-
Qualitative data is also known as categorical data which means that these types of data cannot be counted or measured using numbers and therefore, divided into categories of Data. Some examples of Qualitative data include- Case studies, Photographs, Diary Writing, Documents, etc. These types of data answer “why” or “how” after an analysis. It is important to determine traits or characteristics and their frequency. Understanding your data can help you to understand your customers better, which will make you happier in the long run. Qualitative data ensures what problems users face and how they can be addressed or improved.
Some characteristics of Qualitative data include-
This kind of data has both benefits and drawbacks.
Pros of Qualitative data-
Cons of Qualitative Data-
i) Interviews- Personal interviews are one of the most commonly used qualitative data collection methods for qualitative research, because of their personal approach. The interview is often conversational in nature and the interviewer or the researcher collects data directly.
ii) Group Discussions- Group discussions are held with 6 to 10 people where the moderator assigns a particular topic to be discussed. Depending on the qualitative data that is needed, the members of the group may have something in common.
iii) Observation- Observation is a lengthy qualitative data collection method where the researcher simply observes behaviors in a participant. They keep a close eye on the participants and take transcription notes to find innate answers and reactions without inducement.
Qualitative Data collection tools-
Every data collection is incomplete without the right set of tools. Here are some of them-
There are two sub-categories of Qualitative data- Nominal Data & Ordinal Data.
Nominal Data- Nominal data, also called “Labeled” or “Named” data, are the types of data that are used to label or name something without the use of numerical. Data analysts use nominal data to identify the differences among datasets. These types of data are useful while conducting research when there is freedom of opinion. A multiple-choice test of a candidate can be identified as nominal data.
Ordinal Data- Ordinal data is a category of qualitative data which has a natural order while maintaining a class of values. When researchers use ordinal data, the order of the data matters more than the differences. Data analysts might use these types of data while preparing charts or to classify groups. These data help in deciding which coding strategy will work the best for the particular data.

These types of data quantify things by the use of numbers that make them countable in nature. This means you can gather percentages and statistics and analyze your results using graphs and charts. Most of the data found by quantitative methods are less prone to bias and can often accommodate a larger sample size than the data collected. Quantitative data is used when a researcher needs to solve a problem, and answers questions like “what,” “how many,” and “how often.” These types of data are frequently used in math calculations, algorithms, or statistical analysis. Some examples of this category include- Experiment results, time in days or weeks, age in months or years, distance in km/m, etc.
Some characteristics of Quantitative data include-
There are both benefits and drawbacks of this kind of data.
Pros of Quantitative data-
Cons of Quantitative Data-
i) Questionnaires and Surveys- Surveys and questionnaires are commonly used in quantitative research because they are useful for gathering in-depth feedback from users and customers, particularly for finding out how people feel about a certain product, service, or experience. With a wide range of simple-to-use tools, conducting online surveys is a fast and practical search method.
ii) Experiments- An experiment is another common type of quantitative data collection method which includes a control and an experimental group. The data collected is extensive as it pertains to a set of records involved in the experiment.
iii) Sampling- Sampling is the process of selecting a sample of data, which can save both time and resources. There are two ways of this process- Random sampling and Non-random sampling.
There are a variety of tools that are used by data analysts and researchers for these types of data collection. Some of them are-

There are two subcategories of Quantitative data. ThContinuous Data– ey are- Discrete Data and Continuous Data.
Discrete Data- These types of data include numerical data that are integers or whole numbers. These data types used in statistics cannot be measured, they can only be counted as objects that have a fixed value. Some examples of this type of data include- the number of players in a team, the number of employees in a company, etc. Discrete data can usually be displayed by pie charts or bar graphs.
Continuous data can take any numerical and can vary. Unlike discrete data, continuous data can be broken into smaller pieces like fractions and can take any value. Examples of these types of data include- web traffic, wind speed, the temperature of the water, etc. Since continuous data changes over time, they are best represented through graphs or grouped into categories. Continuous data can be subdivided into Interval data and Ratio data. Interval data is always measured in numbers where the distance between two points is equal. Ratio data can be measured on a continuous scale but has a true zero.
After getting deep insights into different kinds of data, it’s time to understand the key differences between these two types of data.
