2. The History of Analytics

In 1785, William Playfair introduced the concept of the bar chart, one of the most basic and widely used data visualization features. In 1890, Herman Hollerith invented the “tabulating machine,” which recorded data on punched cards. This allowed for faster data analysis, accelerating the US Census counting process from seven years to just 18 months. In the 1970s-1980s, the development of relational databases (RDB) and Structured Query Language (SQL) software allowed for the extrapolation of data for customized analysis. By the late 1980s, William H. Inmon proposed the concept of a “data warehouse,” where information could be quickly accessed and repeatedly used. In the 1990s, the concept of data mining allowed businesses to analyze and explore patterns in large datasets.

Data analysts and data scientists flocked to programming languages like R and Python to develop machine learning algorithms, work with large datasets, and create complex data visualizations. By the 2000s, innovations in web search led to the development of MapReduce, Apache Hadoop, and Apache Cassandra to help explore, prepare, and present information.

II. What is Data Analytics?

1. Definition of Data Analytics

Data Analytics refers to the process of examining, cleaning, transforming, and modeling data. The goal of Data Analytics is to uncover useful information, inform conclusions, and support decision-making. There are various methods and techniques for data analysis, but analysts choose the most appropriate method depending on the industry and purpose.

2. Some Terms in Data Analytics

  • Data Visualization: Presenting information in graphs or images to clearly and attractively illustrate trends and patterns. This skill is essential when analysts need to present key conclusions to upper management.

  • Exploratory Data Analysis: A method for interpreting data using various statistical charts, encouraging testing and experimentation before making assumptions.

  • Data Model: A way of organizing and structuring data elements, establishing relationships between different types of information to create visual models.

  • Analytical Database: Software that maintains and facilitates data manipulation.

  • Data Cleaning/Data Cleansing: The activity of identifying and removing inaccurate, faulty, or irrelevant data points. Data cleaning is often the first step in the analysis process.

III. Distinguishing Data Analytics and Data Analysis

The main difference between Data Analytics and Data Analysis lies in their scope. Data Analytics is a broader term, while Data Analysis is just one component. Data Analytics is a comprehensive field or discipline that includes the management of entire datasets.

This encompasses not only analysis but also the collection, organization, storage of data, and all the tools and techniques used. Data Analysis, on the other hand, refers to the process of examining, transforming, and organizing a specific dataset in particular ways to study its individual components and extract useful information.

IV. Benefits of Data Analytics in Business

1. Improved Decision Accuracy

Thorough data analysis helps business owners make well-informed decisions based on solid foundations, eliminating subjective guesswork when proposing plans. Moreover, this process provides a detailed understanding of customer problems, enabling decisions to improve relevant programs and plans. With the advancement of modern data analytics technology, you can continuously collect and analyze new data, updating the latest information in real-time.

2. More Effective Marketing Campaigns

A successful and effective marketing campaign always starts with a deep understanding of the target customers. Data Analytics plays a critical role in helping marketers collect and analyze customer data to uncover insights, understand needs, and consumer behavior, thus proposing marketing campaigns that resonate with the target audience. Nowadays, there are many Data Analytics tools that help gather insights and identify which group is likely to engage with campaigns and have a higher conversion potential.

3. Better Customer Service

Thanks to data analysis, businesses gain a better understanding of customer needs, enabling them to provide more relevant services that improve customer relationships. Moreover, modern Data Analytics tools can also personalize information, showing customized interfaces for each customer group in the behavioral classification funnel.

4. More Efficient Operations

Data Analytics helps businesses streamline operations, save costs, and optimize business results. Once you know what customers want, you can save more time by designing advertisements that align with the needs of your target audience.

V. Types of Data Analytics

  • Descriptive Analysis: Descriptive analysis helps summarize large datasets to describe outcomes for stakeholders. By developing performance indicators (KPIs), return on investment (ROI), and other specialized metrics to monitor performance, success, or failure in specific industries. This process involves collecting relevant data, processing it, analyzing it, and visualizing it to provide insights into past performance.

  • Predictive Analysis: Predictive analysis helps answer questions about what will happen in the future. These techniques use historical data to identify trends and determine if they are likely to recur. Predictive tools provide valuable insights into potential future events, utilizing various statistical and machine learning techniques, such as neural networks, decision trees, and regression.

  • Diagnostic Analysis: Diagnostic analysis helps answer questions about why something happened. These techniques complement basic descriptive analysis. From the findings of descriptive analysis, you can dig deeper to identify the causes. Performance metrics are further examined to determine why they improved or declined. This process generally consists of three steps: Identifying anomalies in the data, collecting relevant data about these anomalies, and using statistical techniques to find relationships and trends that explain these anomalies.

  • Prescriptive Analysis: Prescriptive analysis helps answer questions about what you should do. By using insights from predictive analysis, businesses can make data-driven decisions. This enables companies to make informed decisions when facing uncertainty. Prescriptive analysis techniques rely on machine learning strategies, computer science, and mathematics. By analyzing past decisions and events, you can estimate the likelihood of various outcomes.

VI. Data Analysis Process

  • Data Requirement: The first step is to identify the type of data needed for the task or problem to be analyzed. For example, if you want to know the purchase conversion rate, you need to know the total number of users who visit the site and the total number of users who make a purchase.

  • Data Collection: After determining the necessary data, you will need to gather the data using various methods. The collected data must be highly accurate and error-free. If the collected data is inaccurate, the conclusions drawn will be incorrect.

  • Data Processing: The raw data collected must be organized and distributed in a scientific manner. You can organize the data in Excel using rows and columns.

  • Data Cleaning: Not all data is useful; some data may contain errors. Therefore, at this stage, data is cleaned, corrected, or errors are removed. To ensure accuracy, this step must be handled carefully.

  • Data Analysis: This is arguably the most mentally demanding step because you need to use the analyzed data to draw conclusions. You can use data analysis tools and techniques to visualize data, analyze correlations, and perform regressions.

  • Communication: After completing the data analysis, you need to transform it into useful information, simplifying it in the form of charts, tables, or graphs to interpret, present, discuss, and communicate with the stakeholders who need to use the analysis results, such as leaders, directors, and project managers.
