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?

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”
