My favorite cereal! I had many different favorite cereals over the years: Raisin Bran, Krave, Fruity Pebbles. But in the end of my cereal eating era (there are only two I eat from time to time now), it was the Special K Chocolatey Delight that had me in a chokehold.
Have you walked into cereal aisles recently? There are like, a thousand options. That’s a lot of nutrition labels to read…
That’s why the data set I chose for this ‘Data Project’ is a cereal dataset!
My Cereal Data
Admittedly, this project was the bane of my existence and my headache the entire week. I don’t use Microsoft often, much less Excel, numbers are not my jam, and I simply didn’t (genuinely) have time to go to the DKC for help (which was part of my headache). I like making pretty things and looking at pretty things. Very different. I don’t like how my charts or tables look but I am so ready to stop looking at them. I digress, nothing is easy when you first do it, so a little struggle is healthy, but respectfully, I am so glad that this part is over:P
I got my cereal data from Kaggle btw!
Trend
So, I know we all had a moment in our upbringing when someone told us that cereal isn’t healthy and it was like this crazy realization so much so that we went into a rabbit hole of cereal nutrition labels (…no? Just me?), so instead of focusing on things like sugar and carbs which we all know cereals tend to have a quite a bit of, I wanted to see if there were any trends between any other parts of the nutrition labels. What I found (and chose to focus on) was that a strong positive correlation exists between fiber and potassium, indicating that cereals high in fiber are also likely to be high in potassium and cereals manufactured by Nabisco tend to have the highest average fiber content (therefore, they also have a higher average potassium content per serving)! Yay for no muscle cramps and regularity, if you know what I mean…
How?
How did I find this trend? Well, after I loaded the downloaded and loaded the data into Excel, I went through and deleted and columns and rows that I didn’t find relevant or didn’t want to analyze. I made a chart using the ‘Format as Chart’ button in Excel, and inserted a Pivot Table using that button. With the Pivot Table feature, you can make your own perfect storm of variables that you want to look at next to each other so that its easier to compare and well, analyze. I spent the most time doing this. I clicked around, adding and taking away different nutritional variables but always keeping the cereal name present. In the value field, I made sure I always had ‘average’ instead of ‘sum’ that way I was always looking at the averages of the numbers in front of me instead of what they added up to be. Everything I said is basically everything Professor Berge goes over in this video. Once I thought I saw a trend (the one I mentioned earlier), I asked ChatGPT how to calculate a correlation because I wanted to make sure I wasn’t just imagining it (lol) and these are the instructions it gave me:
- Click on an empty cell where you want to display the correlation value.
2. Enter the formula: =CORREL(range_fiber, range_potass), replacing range_fiber and range_potass with the actual cell ranges for the fiber and potassium columns, respectively (e.g., =CORREL(B2:B101, C2:C101)).
3. Press Enter to calculate the correlation. The result will indicate the strength of the relationship between fiber and potassium. A value close to 1 indicates a strong positive correlation.
…To which the value was 0.90! I was not, in fact, imagining it.
That’s when I decided to move some more values around and see which manufacturers cereals tend to have the highest fiber and potassium contents and I landed with Nabisco. I didn’t make a chart for that, however (Remember? Bane of my existence?).
So, All-Bran with Extra Fiber does, in fact, beat the rest of cereals in fiber content. Period.
