# Day 177: Skittles

Last night I went and bought 8 pounds of Skittles; I had a fun conversation with the cashier.

Algebra looked at the color distribution of the different sized bags of skittles and made some conclusions on the data.

Here’s how things went.

I threw up this picture and asked ’em how many Skittles thy thought were in the package, then their estimated percent breakdown of each color.

After, I put this up and asked if it changed any if their answers.

They saw the number of each color and calculated the percentage of each.

111 Skittles isn’t a great size to make any conclusions, they asked for a larger bag and then made the same estimations.

389 Skittles isn’t really enough to make conclusions either… the data was everywhere.

Then, I pulled out a 2 pound bag of Skittles, broke students into groups of 2 and had them find the frequency of each color.

I put together a quick Excel document and had running totals throughout the day.

The results of each 2 pound bag were different, but when we put them together and looked at a sample size of 4338 some interesting talking points emerge.

I am excited to hear what students have to say/conclude from this data on Monday.

# Day 171: Graphs

The last week of algebra consists of an introduction to statistics. They start the whole process by reviewing (for most) how to interpret graphs. Normally, this isn’t a very exciting process but I found some fun graphs to spice things up.

First I put up a blank slate and them ’em guess what it could be:

Turned out to be something like grams of fat for ingredients of a sandwich.

After we went through all the different types of graphs, here are my favorite examples of each:

Gotta keep content interesting with the end of the year looming….
