Exercise 2,
Continued.
7. Forget all about questions one through six, above. Assume
you see shape 28c for the first time. You go to the woods and
collect a sample of similar shapes. When you examine them you find
equal numbers of shapes 28b and 28c. What might explain this?
Explain your answer.
8. Same facts as seven, above, except the shapes are all
different colors. What might explain this? Explain your answer.
9. Forget all about the questions above. You go to some nearby
woods and find the shapes all look like 28c. Then you travel to
some woods in a nearby state. All the shapes found here look like
28b, except they are a blueish color. What might explain this?
Explain your answer.
Exercise 3 - Quizzing Others About Categories For Species
Go to page 18 and find the slide that says "Cryptic
Tropical dwelling" on the top.
Show the slide to an older member of your household. See if he or
she can correctly match the terms shown on the slide. See if he or
she can guess that the terms refer to a way of classifying
species. If the person doesn’t know the answers, be a good
teacher and help them learn! Talk about your experience in class.
Exercise 4 - Using Nominal, Ordinal and Interval Categories
In class we discussed six different types of categories for
classification systems: Objective and subjective Qualitative
Nominal Categories, objective and subjective Quantitative Ordinal
Categories, and objective and subjective Quantitative Interval
Categories. (See pages 15,
16, and 17
for review.) In this exercise we will practice making these
categories.
1. Go to page 21 and fill in the blanks on the "To
Classify is to Sort Worksheet." Think of objective and
subjective ways people and jobs can be classified nominally,
ordinally and intervally.
2. Pick a room in your house–your bedroom, for example. Look
at the things in the room. Use the items you see to create six
classifications. After you have created them, label each of them
according to one of the six types of classification systems we
have discussed.
3. Using one of the classifications you created in number 2,
above, and referring to the mind map "Some Purposes of
Classification" on page 20, write two or three paragraphs
explaining how your classification of objects serves the general
purposes of classification and one or more special purposes of
classification. (Note: You may create a new special purpose if you’d
like to.)
