- A scholar's gender
- A scholar's age
- The hours of snooze a scholar gets per night
- A scholar's year in the college
- A scholar's vulgar grade
- The compute of pets a scholar owns
In a 2- to 3-page Microsoft Word instrument, oration the forthcoming:
- Identify the recalcitrant and relative waverings in this con-over. For the recalcitrant waverings, expound what can be the likely levels (subcategories amid each wavering) of the waverings or the collocate of values.
- Explain the relationship betwixt the exemplification and the population in the con-over.
- Identify the laminas of extent (nominal, ordinal, space-between, and agreement) for each of the waverings. Expound why the lamina of extent you chose is misapply for this con-over. Some waverings bear more than one likely lamina of extent; so influence your rationalistic after a while examples.
- In one of the zealot's classes, scholars' evaluations of her (scored on a lamina of 1 to 10) are as follows: 3, 5, 5, 5, 5, 6, 6, 8, 8, and 9. For these evaluations:
- Calculate ( X)/n.
- The university changes its scoring plan, and now the scholars' evaluations are scored on a lamina of 5 to 15. For these evaluations:
- Calculate ( (X + 5))/n.
- The zealot wants to see what would occur if each scholar gives her one subject-matter preferable. Describe the formula to number that.
