Lesson 2: Data Management Challenge and Opportunity What is data management? Why data management is important? Data management is the practice of collecting, Data management is a crucial first step to employing organizing, protecting, and storing an organization’s effective data analysis at scale, which leads to data so it can be analyzed for business decisions. As important insights that add value to your customers organizations create and consume data at and improve your bottom line.

Clearly communicating data usage policies to customers to build trust and foster transparency. Heat Maps Example: Providing a detailed privacy policy that Visual tools that represent data density or activity explains how guest data is collected, used, and levels, highlighting areas of high and low protected, reassuring guests about their data concentration. privacy. Example: A heat map of a hotel's floor plan reveals high-traffic areas, guiding decisions on layout adjustments and staffing needs to improve guest experience. Graphs and Charts Various formats such as bar charts, line graphs, and pie charts that present data in an easily interpretable manner. Example: A pie chart showing the percentage of bookings from different marketing channels helps allocate marketing budgets more effectively. Geospatial Mapping Maps that display data based on geographic location, providing spatial context to data analysis. Example: A map illustrating guest origins allows a hotel chain to tailor marketing efforts to specific regions, enhancing targeted advertising and promotional campaigns. Lesson 4: Data Handling in Analytics Visualization Types and Creating Powerful Visualizations Introduction to Data Handling Purpose: Display trends over time by connecting data Definition: Data handling encompasses the methods points with a continuous line. and practices used to collect, process, and manage Usage: Best for illustrating temporal changes and data efficiently. trends. Collecting: Gathering raw data from various sources. Example: Monthly revenue growth. Processing: Cleaning, transforming, and organizing Advantages: Good for showing trends and patterns. data. Drawbacks: Less effective for comparing individual Managing: Storing, retrieving, and maintaining data data points. integrity. Pie Charts Importance: Proper data handling is crucial for deriving accurate insights and making informed decisions. Visualization Types Bar Charts Purpose: Show proportions or percentages of a whole. Usage: Useful for displaying relative sizes of categories. Example: Market share distribution among competitors. Advantages: Visually appealing; easy to understand Purpose: Compare and visualize quantities across proportionate data. different categories. Drawbacks: Less effective with many categories; can Usage: Ideal for showing discrete data and be hard to compare similar sizes. comparisons. Scatter Plots and Correlation Example: Sales figures across different regions. Advantages: Simple to understand; effective for categorical comparisons. Drawbacks: Can be misleading with too many categories. Line Charts Purpose: Explore the relationship between two quantitative variables. Usage: Identifying correlations and patterns between variables. Example: Relationship between advertising spend and sales. Advantages: Useful for detecting correlations and outliers. Drawbacks: Less intuitive for those unfamiliar with scatter plots. Heat Maps Design Principles Clarity: Ensure the visualization is easy to understand at a glance. Avoid clutter and unnecessary elements. Consistency: Use consistent colors, fonts, and styles to make the visualization cohesive and easier to interpret. Highlight Key Insights: Use annotations, Purpose: Represent data density or magnitude using colors, or labels to draw attention to color gradients. important data points or trends. Usage: Visualize data density and patterns in larged Example: atasets. Interactive Elements User activity on a website. Filters: Allow users to interactively filter Advantages: Effective for visualizing complex data data to view specific segments or time periods. sets and identifying patterns. Tooltips: Provide additional context or details Drawbacks: Can be difficult to interpret if not when users hover over data points. designed properly Drill-Downs: Enable users to click and explore Histograms more detailed data or related information Use of Color Contrast: Ensure there is enough contrast between different data series or categories to differentiate them clearly. Color Blindness: Use color palettes that are distinguishable by individuals with color Purpose: Show the distribution of a dataset by blindness, or provide additional visual cues grouping data into bins. (e.g., patterns). Usage: Analyzing the frequency distribution of continuous data. Best Practices for Data Visualization Example: Distribution of customer ages in a survey. Keep it Simple Advantages: Useful for understanding the Focus on the Message: Ensure the visualization distribution of data. clearly conveys the intended message without Drawbacks: Bins can influence interpretation; not unnecessary details. ideal for comparing distributions. Avoid Clutter: Limit the amount of information presented to avoid overwhelming the viewer. Creating Powerful Visualizations Understand Your Data Label Clearly Data Analysis: Perform exploratory data analysis Axes and Titles: Clearly label axes, titles, and (EDA) to understand key metrics, distributions, and legends to ensure the viewer understands the relationships. context.
