In this Pantene advertisment, i have noticed that they have used the method of statistical deception which is bad sampling because they mentioned that 89% who they blind tested said the product was effective. By not saying who they tested, and how long they have tested them proves that they are using bad sampling. Another is, by not saying out of how many people they tested was effective and who were not.
In this advertisment, they are not saying any possibilities that anything could go wrong. How could they possibly say that 100% of the dandruff will be gone? How would they know if the costomers hair will be 10 times stronger? Did they test it with a lot of people to prove that it will become stronger than it was before? And if it does become stronger, it does not say how long you need to use the shampoo so that it will become 10 times stronger.
In this Pantene advertisment, how would they know if it would be 100% protected from any damage? and if so, what kind of damage? it says "up to 100% damage protection", which means it could be less than 100% protection of the constumers hair.
Unfortunately, companies that want you to buy their products, use statistics to make it appear that their claims are more valid than they really are. That is why consumers must be more critical and discriminating. This is an example of having basic knowledge about the principles of statistics can help in making day-to-day decisions.
