Multiple Choice

Use these sets to find the following. Identify any disjoint sets.
-Let $\mathrm { U } = \{ 7,8,9,10,11,12,13,14,15,16,17 \} , \mathrm { M } = \{ 7,9,11,13 \} , \mathrm { N } = \{ 8,10,12,14,16 \}$ , $Q = \{ 7,9,11,13,15,17 \}$ , and $R = \{ 7,8,9,10 \}$ .
$\mathrm { M } \cup \mathrm { N }$

• A) \(\{ 8,9,10,11,12,13,14,15,16 \}\)
• B) \(\{ 7,8,9,10,11,12,16 \}\)
• C) \(\{ 7,8,9,10,11,12,13,14,16 \}\)
• D) \(\varnothing ; \mathrm { M }\) and \(\mathrm { N }\) are disjoint sets.

Definitions:

Alternate Form Reliability

A measure of consistency where different versions of a test produce similar results, indicating the test’s reliability over time.

Concurrent Validity

A measure of how well a particular test correlates with a previously validated measure taken at the same time.

Construct Validity

The extent to which a test or measurement tool accurately measures the theoretical construct it is intended to measure.

Content Validity

The extent to which a test measures all aspects of the concept it intends to measure.
