Introduction
Companies all over the world, be they small or medium, or large, store huge amounts of data. This data is usually raw. To be precise, raw data is that form of data that is vast, unorganized, and not yet processed by a machine or a human. The sources of raw data include satellite images, mail, audio, video, or texts.
Data Analytics is all about converting raw data into a well-organized meaningful form of data and effectively interpreting them. In this process, unimportant data is cleansed or eliminated. Whenever a business identifies particular questions or challenges affecting its business, data analysts address these questions or challenges by visualizing their findings in the form of dashboards, charts, or graphs.
Flashback
Data was manually analyzed in the past, i.e., till the era of black-and-white cinema. This was often expensive and time-consuming. It was only from the 1970s, businesses started using technology in the field of data analytics. As years passed, machine learning algorithms, data warehouses, data visualization, and other tools were involved in the process.
Benefits and Uses of Data Analytics:
Now that we understand what data analytics is, let us find out the benefits a company can enjoy because of data analytics:
- Predict future sales of the organization
- To protect the organization against fraud
- To analyze the effectiveness and efficiency of ad and marketing campaigns
- To improvise supply chain efficiency
- To boost customer retention
After understanding the benefits of Data Analytics, let us now try to find out what are the types and tools used for Data Analytics.
Types of Data Analytics
There are mainly four types of data analytics. They are
Descriptive Data Analytics
Diagnostic Data Analytics
Predictive Data Analytics
Prescriptive Data Analytics
It is important to note that all these types are interconnected and interdependent. Let us try to understand each of the types in detail.
Descriptive Data Analytics: It is a type of analytics that addresses the question of ‘what happened in the past?’ It involves studying present and historical data to identify trends and observe changes over time. It is considered the simplest form of data analytics. Descriptive Data Analytics can be applied to Demand trend analysis, or financial statement analysis are some examples of descriptive analysis.
Diagnostic Data Analytics: This type of analytics tries to answer the question of ‘why did it happen?’ In other words, it is also called root cause analysis. Methods like time series, probability theory, and regression theory are used in this type of data analytics. It tries to get more information from any report by identifying the root cause of several issues, changes, etc. Diagnostic Data Analysis can also help in alerting or notifying some issues even before it occurs in an organization.
Predictive Data Analytics: This type of analytics tries to answer the question of ‘what might happen in the future?’ Historical data is used to understand and forecast future trends and events. Regression analysis is one of the tools used.
Prescriptive Data Analytics: This type of analytics addresses the question of ‘what can be done in the future?’ Based on the results of predictive data analytics, organizations can make informed decisions on what can be the best course of action to tackle risks and improvise their efficiency in the future. It is considered a complex type of data analytics as it involves the usage of algorithms.
Process of Data Analytics
Data Analysts follow 5 main steps when they are working on a project. They are
- Define the question that the organization wants to answer:
A Data Analytics professional should know why they are conducting a particular analysis. Which problem to address? The analyst will make a research question or hypothesis based on this. Here, the analyst should be very clear on what type of data he/she requires and what is the source of that data. For example, a data analyst may want to know why the new product of their organization is not able to increase their sales.
- Collect the data:
In order to collect the data, they may use primary or secondary sources. They can use CRM measures to know the opinions of the customers, analyze trends, conduct online surveys, or try to get data from government websites, or international websites like IMF, World Bank, WHO, etc.
- Cleansing of the data:
Once the data is collected, it should be prepared for analysis. But before analyzing, the collected data might be unorganized and raw. The raw data can contain some unwanted information, or missing information that can be unnecessarily misinterpreted. Data cleaning is a tedious and time-consuming task.
- Analyzing the data:
Once the data is edited, the data will be ready for analysis. In this step, analysts make sure that their research questions will be answered. Techniques like Regression Analysis, Cluster Analysis, Cohort Analysis, Factor Analysis, and Time Series Analysis are used. These techniques are explained in the subsequent section.
- Interpret and share the result:
It is the final step where the data analysts interpret their understanding in the form of a chart, a map, a table, etc after their research. This process is called Data Visualization. With this step, organizations will make their decisions on how to move forward.
Techniques used in Data Analytics
Data Analytics can either be qualitative or quantitative.
Quantitative data can be measured. For example, analyzing the number of responses answered by customers in an online survey. Qualitative data cannot be measured. For example, analyzing how people answer an interview.
Though data analysts mainly work with quantitative data, they are expected to have an understanding of both methods. Broadly, the field of Data Analytics uses 5 methods. They are
Regression Analysis
Cohort Analysis
Time Series Analysis
Cluster Analysis
Factor Analysis
Regression Analysis: It is a technique used to estimate the relationship between dependent and independent variables. Such insights can be very helpful to study historical trends and develop forecasts. An example of regression analysis can be, analyzing the exam scores of students who study for 6 hours a day. Based on these two variables (study hours and scores), analysts can understand if 6 hours of study is fruitful for the students or not.
Cohort Analysis: It is a technique of data analytics where a specific group based on common characteristics is analyzed over a period of time. The behavior of this group is studied. For example, organizations use cohort analysis to understand the customer life cycle which helps them recognize important trends. This type of behavioral analytics can save a lot of time as cohorts with common characteristics rather than analyzing individuals.
Time Series Analysis: It is a technique where data that is recorded over a regular time period is analyzed to discover causes of certain patterns or trends. Time series data is widely used in studying stock prices or weather forecasts. By studying time series data, analysts can come to a conclusion to understand the behavior of different industries.
Cluster Analysis: In this technique, data points are grouped into clusters based on common characteristics, and the patterns of these homogeneous groups are studied. This technique does not require prior knowledge. For example, customers can be divided into different groups based on their geographical location, age, or different factors and the purchasing behavior of each group can be analyzed. This can help business organizations find costumers of high value.
Factor Analysis: In simple words, it is the technique of condensing lots of data variables into a few data variables and a smaller set of factors. It is heavily used in the field of marketing and psychology as it helps in identifying undiscovered and inactive variables which influence customers’ preferences. For example, an organization wants to understand customer preferences for denim jeans, cargo jeans, ripped jeans, slim-fit pants, joggers track pants, gym-wear track pants, and solid track pants. Factor analysis can reduce all these variables into two main variables- Preference for Jeans pants and Track pants.
