This course will teach you how to use large datasets to make critical decisions.

Unit 1: Exploring Data with Excel

Understanding the Value of Data

  • Explore the value of data.
  • Work your way through the data analytics workflow.
  • Unlock the power of Microsoft Excel to utilize its analytical tools — no matter your experience level.
Preparing Data in Excel
  • Learn best practices for collecting and cleaning data in Excel to ensure accurate analysis results.
  • Manipulate real-world data sets using advanced nested logical functions (IF, OR, and AND).
Cleaning Data in Excel
  • Clean large, unruly data sets by removing duplicate rows and performing text manipulations.
  • Transform and rearrange columns and rows within spreadsheets to prepare data for analysis.
  • Gain insight into data analysis by manipulating data formats.
Referencing Data in Excel
  • Use the VLOOKUP and HLOOKUP functions to manipulate data sets.
  • Look up values in other tables using the functions INDEX and MATCH.
Aggregating Data in Excel
  • Summarize data using pivot tables.
  • Execute Excel aggregation commands (SUM, AVERAGE, COUNT, etc.) and their conditional variants (COUNTIF, COUNTBLANKS, etc.) to summarize data sets.
Visualizing Data in Excel
  • Derive insights from data by highlighting cells based on conditionals.
  • Use scatter plots, bar graphs, and histograms to visualize data.
  • Explore color theory and how it applies to data visualization.
  • Build your own data dashboard using industry best practices.
  • Apply visual design principles to your dashboard to present your findings clearly.
Applying Statistics for Data Analysis
  • Understand the value of descriptive and inferential statistics.
  • Learn to describe data and identify outliers using its mean, median, mode, range, and variance.
  • Make predictions about larger populations using sample data.
Building Data Narratives
  • Learn best practices for describing analysis techniques.
  • Communicate insights and implications for stakeholders.
  • Deliver short, effective presentations sharing your findings.
  • Provide context for your audience by identifying and presenting the salient statistics.
Unit 2: Managing Data with SQL

Understanding the Fundamentals of Databases and SQL
  • Practice the fundamentals of Structured Query Language (SQL).
  • Use database schema to design appropriate queries using SQL.
  • Explore the differences between relational databases (tabular data storage) and document-based databases (key-value pairs).
Querying Large Databases in SQL
  • Collect data using standard SQL commands (Create, Update, Truncate, etc.).
  • Filter data using advanced SQL commands (Where, Group By, Having, Order By, Limit).
  • Obtain data by creating relationships between tables using Joins.
  • Gather filtered data using SQL Boolean operators (AND and OR) and SQL conditional operators (=,!=,>,<,IN, and BETWEEN).
Aggregating Data in SQL
  • Create relationships between tables and data points (including has_many and many_to_many) using Join tables.
  • Write Boolean statements with SQL conditional operators (=,!=,>,<,IN, and BETWEEN) and null functions (“IS NULL,” “IS NOT NULL,” and “NVL”).
  • Clean data using SQL mathematical functions (ABS, SIGN, MOD, etc.).
  • Summarize data sets by employing aggregation commands (“Sum,” “Average,” “Count,” etc.).
  • Determine data trends by applying aggregation methods.
Writing Efficient, Dynamic Queries
  • Use CASE statements to structure data and create new attributes.
  • Combine multiple subqueries into one using “WITH AS.”
Creating a Local Database
  • Create a local database using data sets you bring into the classroom.
  • Upload and export data using a local database.
Unit 3: Communicating Data Analysis with Tableau

Exploring the Fundamentals of Tableau

  • Get hands-on, practical experience navigating the Tableau software interface.
  • Connect your data to Tableau and identify the best ways to visualize and display your results.
Visualizing Data and Mapping in Tableau
  • Use bubble graphs to visualize data.
  • Display geocoded information for your data.
Designing Data Dashboards in Tableau
  • Contextualize analysis results by creating Tableau dashboards.
  • Incorporate charts and conditional formatting into your dashboard using supporting information specific to a particular data set.
Working with Data Across Excel, SQL, and Tableau
  • Understand the use of specific data analysis software.
  • Apply all the tools and skills you’ve acquired in Excel, SQL, and Tableau to analyze a data set from start to finish.
Final Project Presentations
