Day 10 — Anomaly Detection: Spotting the Outliers Before They Hurt 🚨 Data storytelling is powerful — but only if your story is true. Today’s challenge focused on data reliability — finding and flagging anomalies that distort insights. 🔹 Applied Z-score detection in Python 🔹 Replicated validation pipeline using SQL (mean + std deviation) 🔹 Visualized flagged months with spikes Because accurate analysis isn’t about finding patterns — it’s about finding truths. 📂 Repo: https://lnkd.in/diJyvFQg #Python #SQL #AnomalyDetection #DataAnalysis #Analytics #PortfolioProject #DataReliability #Storytelling

Excel is great for quick analysis, but it becomes less effective when your data gets bigger or your formulas become more complex. That’s where Python in Excel comes in. It lets you run Python code right inside your spreadsheet — no switching tools, no manual workarounds. In this DataCamp article, I explore how to use Python in Excel for advanced analytics, visualizations, and even machine learning, all within your familiar workflow.

📈 Exploring Matplotlib in Python Taking data visualization to the next level, Matplotlib is a core Python library for creating dynamic and informative visual representations of data. It transforms raw data into clear, impactful visuals. Key Features: Supports line, bar, scatter, pie, and histogram charts. Highly customizable — control colors, labels, and styles. Works seamlessly with NumPy and Pandas. Useful for data exploration, trend analysis, and reporting. Foundation for advanced visualization tools like Seaborn. #DataAnalytics #Python #Matplotlib #DataVisualization #Learningjourney

Python + EDA = Every Data Analyst’s Rollercoaster Ride Step 1: Load the dataset. Step 2: Feel confident. Step 3: Realize half the data is missing. Step 4: Panic. Step 5: Import Pandas, NumPy, Matplotlib, and Seaborn. Step 6: Start finding patterns, visualizing trends, and suddenly… it all makes sense! That’s the beauty of EDA with Python, it turns chaos into clarity. With just a few lines of code, you can uncover stories hidden in millions of rows. Once you master EDA, you stop looking at data… and start seeing through it. What’s your go-to Python trick during EDA? #Python #EDA #DataAnalytics #DataScience #Pandas #Seaborn #AnalyticsJourney

Just wrapped up a data project analyzing customer behavior, I dove deep into the data using Python for EDA, extracted key insights with PostgreSQL, and built a Power BI dashboard to showcase the results. I've summarized the process and findings in this presentation, built using Gamma AI: https://lnkd.in/geua4ZTv #DataAnalytics #PortfolioProject #Python #SQL #PowerBI #GammaAI #DataStorytelling
