My Workflow as a Junior Data Analyst 

1. I understand the business problem

Before touching any dataset, I make sure I fully understand the context and the objective. I clarify:

  • what decision needs to be supported

  • which KPIs matter

  • who the stakeholders are

  • what constraints or assumptions exist

This step ensures that my analysis is aligned with real business needs and not just technical exploration.

 

2. I collect the data

Once the objective is clear, I identify and gather the relevant data sources. This can include:

  • CSV or Excel files

  • SQL databases

  • internal dashboards

  • third‑party datasets

  • public datasets

I also check data availability, access permissions, and potential limitations.

 

3. I clean and prepare the data

Data cleaning is often the most time‑consuming part, but it’s essential. I handle:

  • missing values

  • duplicates

  • inconsistent formats (dates, categories, numbers)

  • outliers

  • structural issues

My goal is to build a clean, reliable dataset that can support accurate analysis.

 

4. I explore the data (Exploratory Data Analysis)

I use descriptive statistics and visual exploration to understand the dataset. I look for:

  • distributions

  • correlations

  • trends

  • anomalies

  • patterns that might influence the analysis

This step helps me identify the most relevant variables and refine the direction of the project.

 

5. I engineer and transform features

To improve the quality of the analysis, I create new variables or transform existing ones. This includes:

  • aggregations

  • encoding categorical variables

  • creating ratios or indicators

  • grouping data by time periods

  • normalizing or scaling values

Feature engineering often reveals insights that raw data cannot show.

 

6. I perform the analysis

Depending on the problem, I apply the appropriate analytical methods:

  • descriptive statistics

  • comparative analysis

  • correlation analysis

  • hypothesis testing

  • segmentation

  • trend analysis

My goal is to answer the business questions with clarity and precision.

 

7. I visualize the insights

I translate the results into clear, actionable visualizations using tools like:

  • Tableau

  • Python (Matplotlib, Seaborn, Plotly…)

I focus on readability, relevance, and impact. Each chart must tell a story and support decision‑making.

 

8. I communicate and present recommendations

I summarize the key findings in a structured and accessible way. I highlight:

  • what the data reveals

  • what actions can be taken

  • what risks or limitations exist

  • what opportunities the business can leverage

My goal is to make insights understandable for both technical and non‑technical audiences.

 

9. I iterate and improve

After presenting the results, I gather feedback from stakeholders. I refine:

  • the visuals

  • the analysis

  • the dataset

  • the recommendations

Iteration ensures that the final output is accurate, relevant, and aligned with expectations.
