5 Essential Data Analyst Skills in 2024 and Beyond: A Guide

Data is the new oil; it is now a ubiquitous fact. It is everywhere, and rapid digitization is enabling organizations to gain insights into their internal processes, business outcomes, and even customer behavior. But in the ever-evolving landscape of 2024, simply collecting data isn't enough.

Approximately 328 million terabytes of data are created every day, but this cannot be used as is for analysis or training ML models. That's why data analysis is one of the most promising career options in 2024 and beyond. A data analyst collects, cleans, and interprets data to help organizations use it for their specific business requirement.

Here is a guide to help you understand the top data analyst skills, from technical to soft skills, that will help you future-proof your career.

Understanding the Landscape of Data Analysis

Data analysis as a career or business function has gained traction recently, as organizations today need tools and resources to help manage large volumes of data. Today, a data analyst typically works on managing data from the time it is collected in the data lake or warehouse to the time it is refined and cleansed for analytics and reporting.

But as technology and digital mediums increase, it creates new complexities. Data today is largely unstructured and in disparate formats. This is because of the multiple inflows of data sources - be it social media, sensors, or smart devices. This sheer volume and variety demands powerful tools and techniques to extract meaningful insights.

Data and AI technology expert Fredric Jacquet says, “Data scientists still spend too much time cleaning data instead of creating actionable insights.” This is because as technology usage increases, so does the level of data complexity and diversity.

This is where Artificial Intelligence (AI) plays a major role. AI can learn from patterns within data, uncovering hidden relationships and predicting future trends. AI platforms then leverage these insights to automate tasks, optimize processes, and even make intelligent decisions.

In this changing future, data analysts are no longer simply analysts; they are becoming architects of intelligent systems, bridging the gap between human ingenuity and algorithmic power.

Master the Core Skills of a Data Analyst

Now that we have touched upon the current landscape of data analytics, let us dig into the must-have skills for a data analyst in 2024. Data analyst skills today no longer just focus on programming or core platforms; they encompass multiple avenues. Let's have a look at the few core skills of a data analyst.

Technical Proficiency: Core Tools and Technologies

Since most of the data handled by organizations is stored in particular formats, data analysts need to be well-versed in the technology that the organizations use. The most common is the use of SQL (Structured Query language), a database management platform, which is required by 90% of data analyst jobs. Others include BI Tools, Excel, Python, R, ETL Tools, NoSQL, and other platforms.

Some of the key data analyst skills include:

• SQL Expertise: No data analyst thrives without understanding the language of databases. SQL empowers you to retrieve, filter, and join data within structured databases, building the foundation for insightful analysis.
• Mastery in Python: This versatile language, with its robust libraries like Pandas and NumPy, lets you manage, manipulate, and analyze data with ease. This forms an essential skill required for data analysts.
• Proficiency in ML Tools: In addition to the database and Business Intelligence (BI) tools, data analyst technical skills also require a strong understanding of ML platforms. Platforms like MarkovML can help unlock the power of probabilistic modeling, allowing you to forecast future trends, analyze textual data with unprecedented accuracy, and uncover hidden patterns. This is crucial for succeeding in a world where AI and digital technologies are constantly evolving, and data analysts must match this expectation.

Statistical Knowledge: Unraveling Data Patterns

12% of all companies require data analysts to know statistics. While this is a small number, it can help significantly as the scope of data analysts moves beyond data cleaning and preparation toward analytics, visualization, and insights.

Data analysts today need to grasp concepts like hypothesis testing, regression analysis, and probability distributions to decipher the story data tells. They also need to identify correlations, assess significance, and avoid statistical pitfalls, making statistical understanding a crucial data analyst skill in 2024.

Data Visualization: Communicating Insights Effectively

Data insights are worthless if they remain locked in spreadsheets or cryptic code. The art of data visualization lies in transforming complex findings into compelling narratives that resonate with your audience. Master tools like Tableau or Power BI to create captivating charts, graphs, and dashboards that illuminate patterns, highlight trends, and tell the story of your data with clarity and impact.

Soft Skills: Navigating the Human Side of Data

Technical expertise is only half the story. The successful data analyst is also a master communicator, storyteller, and collaborator. So, in the future, data analysts need to have:

• The ability to present and communicate insights clearly and concisely, both verbally and in writing.
• Problem-solving abilities to tackle unforeseen challenges and navigate data roadblocks with creativity and resilience.
• Data analyst soft skills like learning to work effectively with diverse stakeholders and translating technical jargon into actionable recommendations.

Continuous Learning: Staying Ahead in a Dynamic Field

Since the data analytics landscape is changing rapidly, data analysts need to stay updated to be relevant. This requires continuous learning and upskilling to stay updated with emerging trends in AI, ML, and data management. Embrace a growth mindset, actively seek out new tools and technologies, and never stop learning and evolving.

Impact of AI and ML on Data Analysis

AI and ML are not just impacting traditional business processes but also redefining the landscape of data analysis. Some of the ways AI and ML are currently being used in data analysis include:

• Automation and Efficiency: Repetitive tasks like data cleaning, feature engineering, and model training can now be automated using robust AI solutions. This frees up data analysts to focus on higher-level activities like strategic analysis, model interpretation, and decision-making.
• Uncovering Hidden Insights: Traditional analysis methods can miss out on complex patterns and subtle relationships within data. Data analysts must focus on training AI algorithms on specific data points that can be implemented in the real world. This model can learn from vast amounts of data and uncover these hidden insights, leading to better decision-making.
• Improving Predictive Analysis: Forecasting future trends and behaviors is crucial for informed decision-making. Data Analyst skills in ML empower analysis to be done using ML models, which can be trained to analyze historical data and identify patterns to predict future events with remarkable accuracy.

Future Directions for Data Analysts

Given the disruption caused by AI, data analysts, too, must embrace this new technology to remain relevant. In the future too, data analyst skills in AI will be the top priority for organizations, and will focus on:

• Domain-Specific Expertise: Data analysts will no longer just be data-specific but need to have a deeper understanding of a specific industry or niche. This can help them tailor and train ML models to help address their unique challenges and optimize business processes. For example, healthcare data analysts can train ML models to detect anomalies in blood samples, helping speed up the detection and prevention of health issues.
• Collaborative Intelligence: As AI evolves, it will not disrupt humans completely. Instead, the future will be about humans and machines working together. Data analysts will be the ones who facilitate this seamless collaboration between AI models and human expertise and can help build robust frameworks for data management and analytics.
