100% of all or nothing

Up to 100% or up to no good?

Wow, my stats post got more view than my rabbits, I’m so happy to see that! Love when people are interested in stats

So now to the subject:
This one is my favourite and was the reason I wanted to start a blog about sneaky stats:

One day I entered the shower of my gym and saw a huge ad for #headandshoulders: „up to 100% flake free hair“
And I thought, yeah and whats the big deal about that? What is the promise behind that ad?
The promise is zero. Unless you dont’t know the likeliness of achiving 100% flake free hair, this piece of information says almost nothing relevant for your buying decision.
Example: I tried to find any hints how the study they derived the results of was conducted. Unfortunately Icould not find more information, so I’ll choose an example…imagine h&s tested their shampoo on 5000 people. And 4999 experienced no improvement concerning dandruff and only one person had 100 percent flake free hair afterwards. Then this ad would still tell the truth. Crazy, hm?
And does this result sound great enough for you to buy a product? I’m not telling that this is the outcome of p&gs research. I just am stating: as long as we dont know more about the distribution of the results (how often was the result of 100% achived? How often the redult of 50% flake free hair? And so on…), we can’t tell if „up to 100%“ tells us any more than: yup, at least one person that used tge product had no dandruff afterwards.

I want to make clear, that I am not doubting the effectiveness of h&s. This is no product review. It’s a promise review if you want to see it that way. An advertisement review.
