What Is Data And What Are The Types Of Data?

Introduction

“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.

What do you mean by Data?

What-do-you-mean-by-Data

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.

Why is Data of utmost importance?

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-

  • Gateway to the solution of problems- Various types of data allow organizations to effectively determine the root cause of problems. With data, we can develop more accurate theories and implement more effective solutions.
  • Get the results you want- Data enables organizations to measure the effectiveness of a particular strategy: When strategies are put in place to meet a challenge, data collection will enable you to determine the performance of your solution and determine if your approach needs to be modified.
  • No more guesswork- Data will help you to explain decisions to your clients. Good solid data will help you to confidently approach your strategies and decisions and anticipate your results. Put an end to guesswork with solid, firm data.
  • Be strategic in your approach- There is no denying that various types of data are designed to build efficiency. Effective data collection and analysis will guide you to implement data where they are needed. Data will also enable organizations to conclude the priorities that need to be addressed.

Types of Data & Its Characteristics

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-

Types-of-Data-

1. Qualitative 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-

  • Subjective- Describing or classifying in an objective way.
  • Detailed- To give extensive detail in full words.
  • Open-ended- There is no limit or boundary to the description.
  • No numerical- Contains no numbers.

Pros & Cons of Qualitative data-

This kind of data has both benefits and drawbacks. 

Pros of Qualitative data-

  • Qualitative data is affordable and requires a small sample.
  • It provides a specific insight into the development.
  • Focuses on the details of personal choices and uses them as data.
  • Provides useful content.

Cons of Qualitative Data-

  • This type of data can be time-consuming and difficult to scale.
  • It may lead to repetition and creates subjective information.
  • This type of data relies completely on the work of the researchers without any statistical analysis.

Qualitative data collection methods-

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-

  • MAXQDA.
  • Full Story
  • ATLAS.ti
  • Quirkos
  • Dedoose

There are two sub-categories of Qualitative data- Nominal Data & Ordinal Data.

  1. 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.

  2. 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.

2. Quantitative 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-

  • Embedded with numerical values and properties.
  • Can predict outcomes.
  • Usage of measuring instruments.
  • Highly reliable results.

Pros & Cons of Quantitative data

There are both benefits and drawbacks of this kind of data. 

Pros of Quantitative data-

  • Less susceptible to bias.
  • It is easier to collect and quicker than qualitative data.
  • It can be checked and tested without any repetitions.

Cons of Quantitative Data-

  • These types of data generally lack context.
  • Conclusions drawn are generally hypothetical.

Quantitative data collection methods-

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.

Quantitative data collection tools-

There are a variety of tools that are used by data analysts and researchers for these types of data collection. Some of them are-

  • R
  • Python
  • Microsoft Excel
  • Tableau

There are two subcategories of Quantitative data. ThContinuous Data– ey are- Discrete Data and Continuous Data.

  1. 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.

  2. 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.
