Answer 1

Correct me if im right or wrong with this problem about statistic

Answer 2

1) Ordinal. You can order the dates (eg: 6/7/2015 comes before 6/8/2015)

2) Nominal. The numbers are simply names. Ways to ID the player. You cannot do math on the numbers.

3) I agree. You can order the planets (mercury, venus, earth, mars, etc etc...)

4) This is actually ratio. We can do math on the distances, intervals make sense, and there is a 0 that makes sense.

5) Correct. Similar to #4

6) This seems too vague. Did you mean the waiting TIME? If so, then that would be ratio (similar to #4 & #5)

7) Correct. You can order the grades as Freshman, Sophomore, Junior, Senior

8) Correct. Similar to #4, #5, and #6

9) You can order the longitudes, and it makes sense to do math on them. So it's actually ratio

10) Agreed. Just like with #2, these numbers are basically a "name" or ID for any given person.
