Fibonacci and the Golden Ratio in Spreadsheets
What do sunflowers, shells, honeybees, the Parthenon, and human arm length measurements have in common? All reflect a remarkable pattern of numbers. Now just where does this intriguing sequence of numbers come about? Let’s discover the Fibonacci sequence and the Golden Ratio and how we can use spreadsheets to calculate them!

Breaking it down: Sample Standard Deviation
We have a set of data and want to understand its characteristics. A great starting point is to measure the central or typical value and the dispersion around that value. In this post, we will focus on the latter – specifically a standard measure of spread known as the sample standard deviation!

Hypothesis Testing with Spreadsheets – Part II
Is the “height success rate” for seeds grown in organic soil significantly higher than that for those grown in the non-organic soil? Let’s use a statistical test to find out! But before we delve in, let’s review the amazing Central Limit Theorem (CLT). Why so remarkable, you may ask? Continue reading “Hypothesis Testing with Spreadsheets – Part II”
Hypothesis Testing with Spreadsheets – Part I
What is the impact of organic soil on a seedling’s height? Will an organically-grown seedling be taller than one grown in non-organic soil? Armed with data, we’ll now tackle these questions by performing a statistical test in a spreadsheet!
To see how we our experimental design and data collection method, please see: www.spreadsheetsolving.com/posts/experiment-spreadsheet Continue reading “Hypothesis Testing with Spreadsheets – Part I”
Design & Conduct Experiments with Spreadsheets
Seeking science experiment ideas? Want to conduct an experiment? Curious about hypothesis testing? Understanding how to design and test an effective experiment is an essential skill. Let’s investigate this research question: What is the impact of organic soil on a seedling’s height?
Spreadsheets are a platform to test an experiment or conduct a research study. With spreadsheets, we can collect & organize data, compute summary statistics, and even test hypotheses!
So, let’s begin our experiment with spreadsheets, statistics, seeds, & soil! Continue reading “Design & Conduct Experiments with Spreadsheets”
Introducing VLOOKUP & College Education Value
A good friend introduced me to a site by Payscale that compares the “value” of a college education through a measure called the ROI (Return on Investment), broadly calculated as the difference between the expected future income stream of a college graduate and the actual cost of attending college. Continue reading “Introducing VLOOKUP & College Education Value”
