What Skills Should You Focus on With Your Data Analytics Project?

Regardless of your level or skillset, data analysts can always improve on the following skills:

  • SQL  – SQL is mainly used for storing and retrieving data from databases, writing queries, and modifying the schema (structure) of a database system. In your data analysis project, be sure to make use of some of the most important SQL commands, such as SELECT, DELETE, CREATE DATABASE, INSERT INTO, ALTER DATABASE, CREATE TABLE, and CREATE INDEX. 
  • Programming – While data analysts don’t need to have advanced coding skills, the ability to program in R or Python lets you use more advanced data science techniques such as machine learning and natural language processing. 
  • Data Cleaning Skills – Data cleaning is the process of preparing data for analysis by removing or modifying data that is incomplete, duplicated, incorrect, or improperly formatted. Fixing spelling and syntax errors, standardizing naming conventions, and correcting mistakes are key skills. 
  • Visualization – As a data analyst, it’s important to communicate your findings with strong visuals that appeal to both technical and non-technical stakeholders. To visualize your data effectively, you need to know the specific use cases for each type of visual, from bar charts to histograms and more. 
  • Microsoft Excel – Data analysts use Excel and other spreadsheet tools to sort, filter, and clean their data. Excel is also a useful tool for doing simple calculations (eg: SUMIF and AVERAGEIF) or combining data using VLOOKUP. 
  • Familiarity With Machine Learning, AI, and NPL – Data analysts with machine learning skills are incredibly valuable, even though machine learning is not an expected skill for most data analyst jobs. While data analytics is primarily concerned with data modeling and applied statistics, machine learning algorithms go a step further in obtaining insights and predicting future trends.

How To Present and Promote Your Data Project

A strong data analytics portfolio doesn’t just showcase technical skills—it tells a clear, compelling story. Each project should demonstrate your ability to solve real problems, communicate insights, and use the right tools effectively.

For every project, include:

  • A clear problem statement: What question were you trying to answer?
  • Tools and methods used: Explain why you chose specific languages, libraries, or platforms.
  • Your process: Outline your steps—data collection, cleaning, analysis, modeling, and visualization.
  • Key findings and recommendations: Summarize the results and what actions they support.
  • Challenges and solutions: Briefly describe any obstacles you encountered and how you solved them.

Aim for variety in your portfolio. A well-rounded collection should include:

  • One exploratory data analysis (EDA) project
  • One data cleaning project
  • One SQL-based project
  • One focused on data visualization

If possible, include one end-to-end project that takes raw data all the way to a final recommendation or model.

To promote your work:

  • Upload code and documentation to GitHub with clear, readable README files.
  • Use Tableau Public for dashboards so employers can view your visualizations online.
  • Post summaries of your projects on LinkedIn, linking to GitHub or Tableau.
  • Consider creating a personal website or portfolio to organize your work in one place.

Presenting your work with clarity and purpose helps you stand out—and signals to employers that you’re ready to work in a professional data role.
