For 3 collections, the mode was 126 and the range is 26. What are the 2 possibilities for the number of items in each collection?

Answer 1

I'm not sure what you are asking.

126 what?

If the mode is 126 and the range is from 120 to 146, you have a positively skewed distribution.

If the mode is 126 and the range is from 104 to 130, you have a negatively skewed distribution.

If the range is 133-159, then it approximates a normal distribution.

Does this answer your question?

Answer 2

No it is not the answer
