1. Which Kellogg's set has the most players that are also featured in another year (1970 to 1983)?
2. Which Kellogg's set has the least number of players that were featured in another set?
3. Since the number of cards varied in the sets, which sets featured the highest and lowest percentage of players that were also featured in another set?
4. Do the sets with more repeats make them better in your opinion? Do you prefer the sets with more players who appear in only one set?
Here is what I came up with for these sets.
|Year||# repeats||# in Set|
