Introduction to Data Analysis & Mindset
What data analysts do, data analyst vs data scientist vs data engineer, the data analysis process: Define → Collect → Clean → Analyze → Visualize → Communicate. Types of analytics: descriptive, diagnostic, predictive, prescriptive. Data types: structured vs unstructured, quantitative vs qualitative. Data literacy fundamentals.
Excel for Data Analysis (Advanced)
Power Query for data import, transformation, and cleaning automation. Pivot Tables and Pivot Charts: multi-dimensional analysis, calculated fields/items, slicers. Advanced formulas: VLOOKUP/XLOOKUP, INDEX/MATCH, SUMIF/COUNTIF arrays, dynamic arrays (FILTER, SORT, UNIQUE). Excel data visualization: chart selection principles, conditional formatting for heatmaps.
SQL for Data Analysts
SQL foundations: SELECT, WHERE, GROUP BY, ORDER BY, HAVING, JOINs (INNER, LEFT, RIGHT, FULL). Aggregate functions: COUNT, SUM, AVG, MIN, MAX. Subqueries and CTEs for complex business questions. Window functions: ROW_NUMBER, RANK, LAG/LEAD, running totals. Real-world queries: customer segmentation, cohort analysis, funnel analysis.
Python for Data Analysis: pandas & numpy
Python setup for data analysis, Jupyter notebooks. NumPy arrays: creation, indexing, mathematical operations, broadcasting. pandas DataFrames: loading data (CSV, Excel, JSON, SQL), inspecting data, selecting and filtering, handling missing values, data type conversion. Merging, joining, groupby aggregations, pivot tables in pandas.
Data Cleaning & Preprocessing
The 80/20 rule of data analysis: why cleaning matters. Identifying data quality issues: duplicates, missing values, outliers, inconsistent formats. Strategies: imputation, removal, capping, encoding. String cleaning with pandas: regex, str methods. Standardizing dates, currencies, and categories. Data cleaning pipeline design.
Exploratory Data Analysis (EDA)
EDA framework: univariate, bivariate, and multivariate analysis. Descriptive statistics: mean, median, mode, variance, standard deviation, skewness, kurtosis. Distribution analysis with histograms, box plots, violin plots. Correlation analysis: Pearson/Spearman, heatmaps. Matplotlib and Seaborn for Python visualizations.
Statistics for Data Analysts
Probability fundamentals, distributions (normal, binomial, Poisson). Sampling methods and sample size. Hypothesis testing: null/alternative hypothesis, p-values, significance levels. t-tests, chi-square tests, ANOVA. Correlation vs causation. Confidence intervals. A/B test analysis: statistical significance, practical significance, business interpretation.
Power BI – Business Intelligence
Power BI Desktop: data import, Power Query Editor for transformations, data modeling (relationships, star schema). DAX fundamentals: calculated columns, measures, CALCULATE, FILTER, time intelligence functions. Building interactive dashboards: charts, maps, slicers, drill-through. Power BI Service: publishing, sharing, and scheduled refresh.
Tableau – Data Visualization
Tableau Desktop interface, connecting to data sources. Calculated fields, parameters, table calculations, LOD (Level of Detail) expressions. Building dashboards: layout, actions, story points. Best practices for data visualization: choosing the right chart, color theory, avoiding misleading visuals. Tableau Public for portfolio publishing.
Capstone: End-to-End Analytics Project
Complete data analytics project across the full lifecycle: business problem definition, data acquisition and cleaning, SQL-based exploration, Python EDA, statistical analysis, Power BI dashboard, and executive presentation. Presentation skills for data storytelling: structuring insights, communicating to non-technical stakeholders, and recommendations framework.
