What Does A Data Analyst Actually Do?

In todays business landscape the value of data is. Companies are recognizing its significance. Consequently, data analysts play a role, in extracting insights and driving business growth from this vast pool of information.

Some responsibilities of a data analyst:

  • Collecting data from different sources
  • Validating, cleaning and organizing messy and complex data sets
  • Storing and managing data securely in databases
  • Writing queries to analyze data and identify patterns
  • Using statistical models and data visualization tools to interpret data
  • Identifying trends, metrics and insights to drive business decisions
  • Creating reports, visualizations and dashboards to share findings

It’s an exciting career path for those who love working with data, identifying hidden patterns, solving problems and creating visual stories from complex information.

A strong math, stats and analysis foundation combined with critical thinking abilities and the skills to translate analytics into business insights make data analysts hugely valuable.

Why Become a Self-Taught Data Analyst?

Historically data analysis skills were gained through advanced degrees like a masters program. But that is changing fast for several reasons:

High Demand

There is an explosive demand for people who can make sense of ever-growing volumes of data across industries. From tech firms, retail brands to public healthcare systems – every sector now relies on skilled data scientists.

According to Glassdoor, demand has caused data analyst salaries to rise nation-wide. Average pay now ranges from $62k to $117k per year.

Accessibility

Self-guided education makes data analytics much more accessible as a career. Short term certificate programs or bootcamps can provide structure, but can be expensive.

However, all core skills can be learned online through highly affordable (or even free) courses. What you prove you can do matters far more than credentials. Portfolios trump grades and degrees.

This makes data analytics an exciting path for mid-career professionals seeking a switch or returning to the workforce – like parents or veterans.

Alignment With Interests

Self-directed learning empowers professionals to shape the direction of their data science expertise through personalized projects. You can craft a unique learning journey that excites you most whether that is:

  • Sports analytics – using data to determine best plays or value players
  • Financial analysis – modeling investment decisions
  • Business intelligence – identifying growth opportunities
  • Marketing analytics – optimizing campaigns
  • Healthcare analytics – detecting diseases and improving treatments

Matching your learning to your interests keeps you engaged, accelerating growth.

In summary – data analytics now delivers an incredible blend of high-income potential, abundant jobs and the flexibility of self-teaching. This makes it an ideal next career for a wide range of professionals.

Learning Key Technical Data Analysis Abilities

While data analysts collaborate heavily with colleagues in other roles like data engineers and scientists, the position relies on independent analysis skills.

SQL Programming

Here are best practices for gaining core technical abilities:

Build a Strong Math Foundation

“Numbers have an important story to tell. They rely on you to give them a voice.” As data analysts, it is our job to interpret numerical data – recognizing patterns, correlations and trends within it to derive insights.

This requires applying principles from:

  • Algebra– Using variables and equations to generalize relationships
  • Statistics – Quantifying trends, variability and certainty
  • Probability – Measuring likelihood of outcomes
  • Calculus – Modeling how quickly things change

Khan Academy offers free online courses to build and refresh your math skills across these critical topics. Math gymnastics flex mental muscles making complex data analysis easier later.

Master Tools Like Excel, SQL and Python

With math fundamentals squared away, it’s time to start working with real data sets. Excel is likely already familiar – but push your spreadsheet skills farther:

  • Formulas for fast inline calculations
  • Pivot tables to dynamically group, filter and summarize data
  • Charts and basic visualizations

SQL allows querying databases, extracting just the data needed for a particular analysis. Syntax takes practice but it is essential for reliably sourcing clean, consistent data sets to work with.

Python

Many analysts eventually learn Python as it offers unparalleled flexibility for data preparation, statistical modeling, machine learning and analysis automation. But it does present a steeper initial learning curve.

For beginners, Excel and SQL offer plenty to sharpen core analytical skills before expanding into Python’s extensive capabilities.

Discover In-Depth Analysis With Data Visualization Tools

Once data is prepared, reporting tools visually communicate insights making data truly actionable for decision makers. Tableau and Microsoft’s Power BI top the list for analysis visualization.

Tableau makes exploratory analysis intuitive – quickly filtering, highlighting outliers, uncovering correlations etc. Visualizations like colored heat maps or tree maps help spot trends.

Power BI enables building sharable dashboards to present key metrics, KPIs and breakdowns to leadership visually. Interactive reporting makes identifying data storylines engaging.

Learning one or both will make you a well-rounded analyst and extremely employable.

Build a Portfolio of Sample Data Analysis Projects

A designer’s portfolio showcases their style and capabilities better than any resume. Data analysts should curate sample projects too.

Open datasets provide great material to demonstrate analysis skills. Kaggle and data.gov host datasets covering:

  • Finance – like markets, investing, cryptocurrency
  • Sports – team/player performance stats
  • Climate – pollution, emissions, energy
  • Education – test scores, funding, demographics
  • Public health – disease rates, hospital metrics, drug trials

Choose data aligning with your interests. Then conduct analysis, create visualizations and write summaries explaining the data story and insights uncovered just as for a real business stakeholder.

GitHub repositories organize these project samples online for employers. Share not just dashboards but also underlying code in Python or SQL to prove your working process from data prep through analysis and reporting.

Honest feedback from peers helps refine analysis and communication for maximum impact.

These projects demonstrate hands-on abilities that no university grade transcript can fully reflect when applying to future jobs.

Develop Critical Soft Skills

While technical expertise is essential, data analysis creating business value further relies on key soft skills:

Data Analyst

Communication

Data analysts work cross-functionally to answer questions that differentiate top companies. This demands clarity in translating numbers and trends into actionable decisions across departments – from operations to marketing, product development to executive leadership.

Build storytelling skills verbally and visually to compellingly explain what insights imply and recommend data-driven actions fitting next business moves.

Creativity

Standard charts only reveal so much. Innovative approaches enable analysts to uncover the hidden stories within data. Experiment analyzing data uniquely using different statistical models, machine learning algorithms, interactive visualizations or even just new data mashups.

Novel combinations can lead to breakthrough perspectives no one else has identified.

Critical Thinking

Reliable analysis requires understanding context to ask the right questions and design appropriate logic flows.

Hone judgement skills by discussing real world business problems and scenarios with friends. Debate root causes. Determine what further data could help disambiguate truths.

Consider if there are relevant ethical implications surrounding findings as well – an increasingly crucial consideration for data analysts influencing real world outcomes at scale.

Sharpening these abilities prepares you to apply technical data skills for maximum business change.

Finding Your First Data Analyst Job

With broad data skills, analysis samples and soft skills demonstrated – it becomes time to start applying for gigs.

Update Resumes and LinkedIn

Data skills evolve quickly. Highlight new analysis tool proficiencies, portfolio projects and their business insights in your resume and LinkedIn profile. Ask peers to endorse your expertise.

Optimize with relevant keywords so talent scouting recruiters can discover your alignment with open positions.

Seek Entry-Level Data Analyst Roles

Major companies now regularly hire more junior data analysts for their training programs given fierce competition. But be open to contract, internship and temp-to-perm roles too which equally build credentials and confidence.

Data analysis spans nearly every industry so cast a wide net if location permits. Look across functions too – marketing analytics, financial data science, operations analysis etc. Opportunity abounds!

Consider Freelancing

Signing on initial data analysis projects independently further builds real-world experience for the resume. Short term freelancing contracts provide flexibility too as you explore long-term career options.

Data visualization services like visual reporting for executive briefings make great early offerings needing less niche expertise. Provide discounts in exchange for client testimonials.

Over time raise rates and expand niche offerings as your analysis skills and network grow.
