Data Analysis
Data Gathering: Collecting data from various sources such as databases, web services, surveys, IoT devices, and external data providers.
Data Cleaning: Removing or correcting incomplete, inconsistent, or inaccurate data to ensure the dataset is accurate and ready for analysis.
Data Transformation: Structuring data into a format suitable for analysis, such as normalizing, aggregating, or encoding categorical variables.
Descriptive Statistics: Summarizing data using mean, median, mode, standard deviation, and other statistical metrics to provide a basic understanding of the data distribution.
Visualization: Creating graphs, charts, and plots (e.g., histograms, scatter plots, box plots) to visually explore relationships, trends, and outliers in the dataset.
Correlation Analysis: Identifying relationships between different variables to understand how one variable impacts another.
Forecasting: Using historical data and statistical models to predict future trends, such as sales forecasts, demand predictions, and stock price movements.
Regression Analysis: Identifying relationships between dependent and independent variables to predict outcomes or determine factors driving performance.
Time Series Analysis: Analyzing data points collected or recorded at specific time intervals (e.g., stock prices, sales data) to forecast future values based on trends and seasonality.
Classification and Clustering: Implementing machine learning algorithms like K-Means, decision trees, or neural networks to categorize data or group similar data points.
Predictive Modeling: Building models that learn from historical data to make predictions about future events (e.g., customer churn, credit scoring, fraud detection).
Natural Language Processing (NLP): Analyzing text data to extract insights, sentiment, or key themes from unstructured data such as reviews, social media posts, or customer feedback.
