# Excel Statistics for Business Analytics

## What you'll learn-and how you can apply it

By the end of this live, hands-on, online course, you’ll understand:

• What variables are, and how to explore them given their type
• How the central limit theorem provides the “missing link” between descriptive and inferential statistics
• How statistics and visualizations each play a part in effective quantitative analysis

And you’ll be able to:

• Explore a dataset for potential research questions, check assumptions and build hypotheses
• Test formally whether the value of one group is greater than another, on average, given their respective samples
• Make compelling business recommendations using inferential statistics

## This training course is for you because...

• You want to apply more rigorous methods to your business decision-making
• You’re an Excel user interested in learning more about data science
• You’re a researcher or analyst looking to apply statistical methods to business

Prerequisites

• Intermediate Excel skills. You should be familiar and comfortable with relative and absolute cell references, PivotTables, and building bar and line charts.
• No previous statistical knowledge required.

• Presentation: The central limit theorem -- saved by the bell curve. Demonstrate the central limit theorem’s role in providing valid inferences about a population, given a sample.
• Presentation: What is a hypothesis and how do you test it? Introduce the concept of hypothesis testing in statistical analysis and how to craft one.
• Presentation: What is a t-test and when do you use it? Introduce the use case for an independent samples t-test, along with how to check for the necessary assumptions and pre-process the data.
• Exercise: Inspect and prepare a dataset to test
• Q&A
• Break (10 minutes)

T-tests for business impact (50 minutes)
