Introduction to Power Pivot

  • Speaker: Kevin
  • Purpose: To demonstrate how to use Power Pivot for data analysis in Excel.
  • Resources: Sample files available in the description.
  • Key Features:
    • Analyze data across multiple tables.
    • Handle large quantities of data.
    • Create data models, calculations, and visualizations with pivot tables and charts.

What is Power Pivot?

  • Definition: An Excel add-in that allows for advanced data analysis, unlike standard pivot tables which are limited to one data table.
  • Benefits:
    • Analyze data from multiple sources.
    • Create relationships between different data sets.

Enabling Power Pivot in Excel

  1. Click on the File menu in Excel.
  2. Go to Options at the bottom.
  3. Select Add-ins on the left pane.
  4. In Inactive application add-ins, find Power Pivot.
  5. Select COM Add-ins from the drop-down menu and click Go.
  6. Check Microsoft Power Pivot for Excel and click OK.
  7. A new Power Pivot tab will appear in the Excel ribbon.

Sample Data Overview

  • Data Files Used:
    • Customers: Customer information, contact details, notes.
    • Orders: Customer ID, order ID, product details, quantities, order dates.
    • Cookie Types: Types of cookies, revenue per cookie, cost per cookie.

Creating a Data Model

  • Definition of Data Model: A collection of tables that relate to one another.
  • Steps to Create a Data Model:
    1. Open Power Pivot and click Manage.
    2. Use Get External Data to import data from Excel files.
    3. Define relationships between tables (e.g., customers to orders, orders to cookie types).

Establishing Relationships

  • Diagram View:
    1. Click on Diagram View in Power Pivot.
    2. Drag and drop to create relationships (e.g., Customer ID from Customers to Orders).
    3. Create one-to-many relationships (one customer can have many orders).

Adding Calculations

  • Calculating Revenue, Cost, and Profit:
    1. Add columns for revenue, cost, and profit in the Orders table.
    2. Use formulas to calculate these values based on relationships defined (e.g., revenue = units sold * revenue per cookie).

Using Measures for Summaries

  • Creating Measures:
    1. Go back to the main Excel sheet and define measures (e.g., total customers, total profit).
    2. Use the Measures option to create new calculations.
    3. Examples:
    • Total number of customers.
    • Total profit across all orders.
    • Average profit per customer.

Visualizing Data

  • Inserting Pivot Tables:
    1. Go to Insert > Pivot Table.
    2. Select Use this Workbook’s Data Model option.
    3. Choose fields to visualize data (e.g., customer names, count of orders).
  • Using Pivot Charts:
    1. Insert a Pivot Chart to visualize data graphically.
    2. Utilize slicers to filter data (e.g., by cookie type).

Key Performance Indicators (KPIs)

  • Creating KPIs:
    1. Define target profits per customer.
    2. Use color coding (red, yellow, green) to indicate performance against targets.
