Introduction

• The power of data analysis using Excel
• What you should know

1. Foundational Concepts of Data Analysis

• Calculate mean and median values
• Measure maximums, minimums, and other data characteristics
• Analyze data using variance and standard deviation
• Introducing the central limit theorem
• Analyze a population using data samples
• Identify and minimize sources of error

2. Visualize Data

• Group data using histograms
• Identify relationships using XY scatter charts
• Visualize data using logarithmic scales
• Add trendlines to charts
• Forecast future results
• Calculate running averages

3. Test a Hypothesis

• Formulate a hypothesis
• Interpret the results of your analysis
• Consider the limits of hypothesis testing

4. Utilize Data Distributions

• Use the normal distribution
• Use the exponential distribution
