Analytics has revolutionized the way businesses operate in recent times. The rise of big data and the need to make data-driven decisions has made analytics a must-have skill for almost every business function. The demand for analytics experts has grown significantly, making it a lucrative career option for many. However, learning analytics can be a daunting task, as there are various tools, techniques, and programming languages to learn. In this article, we will explore how to learn analytics, step by step guide.
Step 1: Know the Basics of Statistics
Before diving into analytics, it is essential to have a basic understanding of Statistics. Knowing statistical concepts like mean, median, mode, standard deviation is fundamental to understanding analytics metrics. There are many online resources available, such as Khan Academy, Coursera, and edX, which provide free courses on Statistics.
Step 2: Get Familiar with Analytics Tools
Learning analytics tools is the second step towards mastering analytics. The most popular analytics tool is Microsoft Excel, which is used to perform most data analysis tasks. It is essential to learn Excel’s advanced functionality like Pivot Tables, Functions, Graphs, and Charts, which will ease data analysis. There are other analytics tools like Python, R, and SAS, which have analytical capabilities far beyond Excel.
Python is an open-source programming language known for its versatility, ease of learning, and vast libraries. R is a statistical programming language popular for its visualization and analysis capabilities. SAS is a proprietary analytics software widely popular with enterprise clients.
Step 3: Learn Data Visualizations
Data visualization is the art of representing data in a graphical or pictorial form, which makes information easily understandable. Analytics is incomplete without data visualizations; it enables easy interpretation of data to drive valuable insights. Tableau is the most popular data visualization tool, which helps create interactive dashboards and reports. Other visualization tools include Power BI, QlikView, Spotfire, and Google Data Studio.
Step 4: Data Wrangling
Data wrangling is the process of transforming data from one format to another for analysis. It involves cleaning data, removing duplicates, and changing data types from columns that are not relevant. SQL, NoSql, and ETL (Extract Transform Load) tools are used for data wrangling.
SQL (Structured Query Language) is a programming language used to manipulate, store, and retrieve data stored in relational databases. NoSql is a non-relational database technology mainly used for unstructured data storage. ETL tools enable users to extract data from multiple sources, transform, and load it into a target location.
Step 5: Learn Advanced Analytics
Advanced analytics is the utilization of complex analytical methods such as machine learning, predictive modeling, and algorithms to generate insights from data. Machine learning is the process of training a model to make predictions based on data input. Predictive modeling is the process of forecasting future outcomes based on historical data. Algorithms are the set of rules or instructions that a computer program follows to solve a problem.
Python and R are the preferred languages for advanced analytics. Some of the popular libraries in Python are Scikit-Learn, TensorFlow, and Keras. In R, libraries like Caret and Zelig are used for predictive modeling.
Step 6: Practice Analytics
To master analytics, practicing on real-world data is essential. Kaggle is a data science platform that provides public datasets for aspiring machine learning engineers and data scientists. By participating in Kaggle competitions, learners can apply their analytics skills to solve real-life business problems.
Step 7: Start Working on Analytics Projects
Gaining practical experience in data analysis is a must-have skill for any analytics expert. Working on real-world analytics problems will help learners hone their analytics skills. Analytics projects can range from predicting customer churn to identifying fraudulent transactions. Start with small projects and gradually increase the complexity.
Step 8: Join Analytics Communities
Joining analytics communities is an excellent way to network with fellow analytics enthusiasts, share your experiences, and learn from one another. Popular analytics communities include Kaggle, Analytics Vidhya, Data Science Central, and Stack Overflow.
Conclusion
Analytics is a skill that requires dedication, practice, and hard work. By following the above steps, learners can quickly become proficient in analytics. Building a strong foundation in Statistics, Analytics tools, and Data visualization is essential. Learning advanced analytics, practicing on real-world data, working on analytics projects, and joining analytics communities will help learners hone their analytics skills. Mastering analytics is a continuous process, as the field is continually evolving with new technologies, concepts, and methodologies.
