Data exploration

You might have answered or seen /u/AsparagusSoupXB1 MyProtein Impact Whey Protein - Flavor rating survey 2018. I wanted to explore the data a bit and I wanted to know what is the best flavor, so he kindly granted my access to the survey results so I could plot in a bit more intuitive way than th previous piecharts that we had (piecharts are baaaad). Having a first look at the data, it looked pretty messy:

##    Banana Boston Cream Pie Butter Pecan Canadian Maple Chocolate Brownie
## 1:     NA               NA           NA             NA                 4
## 2:     NA               NA           NA             NA                NA
## 3:     NA               NA           NA             NA                NA
## 4:     NA               NA           NA             NA                NA
## 5:     NA               NA           NA             NA                NA

As you can see, lots of NA values (understandably, people didn’t rated all 62 flavors). When plotting the number of answers for each participant, results were expected: The histogram show the number of answers for each person. We clearly can see 2 small peaks at 25 and 62. These people thought they had to fill in every answer to see the results. (The one who stopped at 25 didn’t bother filling results for non US stores). We’ll remove them from our analysis. On average, each participant rated 1.6 flavors.

By looking at the number of answers for each flavor, we also can have a first idea of the most popular flavors: But will the Boston cream pie, Banana and Strawberry cream will hold up when looking at the ratings? By the way, we also can note the huge difference in answer given between US and Non-US stores.

Best flavors

I’ve calculated the mean for each flavor, and ranked them by descending order:

Chocolate smooth, strawberry caramel and chocolate caramel make the podium here! Too bad for Vanilla, only 4th (it’s my personal favorite). To examine the breakdown of ratings for each flavor, I picked the 9 top ones (with an average rating >3) and plotted them together: As we can see, there are a lot of 5 for Chocolate Smooth! It’s a no match here. Salted Caramel seems to have more 4 than the other flavors.

Hope y’all enjoyed looking at the results. And I hope that will help you make your choice when picking the flavor you want. Once again, thanks to /u/AsparagusSoupXB1 for the survey!
