When is statistics most effective

I find facts and statistics most effective when it’s used to show a big difference in something but it also depends on how the data is used. For example how much sugars are in fruit and candy. The candy will obviously have more sugar and have a bigger negative effect on the consumer. Chapter 7 had an example about comparing the numbers of bike theft. If the numbers were small then people won’t think of it as a big problem but if it was a big number like the thousands then it would seem more problematic. Statistics like I mention at first about the small number of bike theft from chapter 7 would not be as effective. If the numbers are too small then people won’t want to care about it or to take notice.
