What’s the expected value of your Powerball ticket?

As the Powerball jackpot grows to over $300 million, we start to wonder if maybe buying a ticket is “worth it.” While the lottery is “worth it” in that ticket sales goes to things like state education, buying tickets is typically not worth it for yo because the projected payoff is far less than the ticket price.

What are the chances a Little League baseball player gets to the Major Leagues someday?

baseballIt’s that time of the year when Little League World Series coverage heats up on ESPN, and viewers get to see a miniaturized version of baseball played at the highest level. This year has been especially impressive with a super-team from Las Vegas that rarely makes errors, the Chicago team that beat them, and of course the sensational female pitcher Mo’ne Davis, who throws as hard as some high school pitchers. Every Little Leaguer dreams of making it to the big leagues, someday making a career of playing the game they love.  But how hard is it to get there? This is a question that we will try to solve this week with the help of a spreadsheet.

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

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”

Should schools adopt B.Y.O.T?

A new trend across schools has emerged:  B.Y.O.T for Bring Your Own Technology.   Recently, an article in the New York Times describes the debate of whether schools should adopt B.Y.O.T.   Are you a fan or a critic of B.Y.O.T?  Do the advantages of adopting this policy outweigh the drawbacks, or do they not?  How can we think about this?  Before you answer our poll, let’s first discover how we can use a spreadsheet to develop a logical framework to better inform our opinion!

Pythagoras and SUMSQ

Ever heard of the philosopher and mathematician, Pythagoras of the 6th century BC? Perhaps you’ve come across one his most famous theorems during your geometry class. The Pythagorean Theorem states that in a right triangle, the sum of the legs squared is equal to the hypotenuse squared.

How Analytics & Spreadsheets are changing the NBA

“‘Most teams are using spreadsheets or just using our reports,’ says Brian Kopp, executive vice-president at STATS. ‘The Raptors go a step beyond that, which only a few teams are doing, and their visualizations are the best I’ve seen.'”

This quote is taken from a piece describing how technology, statistics, and analytics are changing basketball.
