MULTIPLE CHOICE
1. A shepherd in the wilds of eastern Nevada is counting his sheep at the end of a work day.
What is another term for what he is doing?
a. Estimating random error
b. Measuring
c. Using an interval level of measurement
d. Calculating risk ratios
ANS: B
Measurement is the process of assigning numbers to objects, events, or situations in accord
with some rule. The numbers assigned can indicate numerical values or categories for the
objects being measured for research or practice.

2. What kind of reliability testing is used extensively in qualitative research?
a. Equivalence reliability
b. Stability reliability
c. External consistency
d. Internal consistency
ANS: A
Equivalence reliability compares two versions of the same paper-and-pencil instrument or
two observers measuring the same event. Determining interrater reliability is a concern when
studies include observational measurement, which is common in qualitative research.
Interrater reliability values need to be reported in any study in which observational data are
collected or judgments are made by two or more data gatherers. Consequently, it is used in
various types of qualitative research in which data or behaviors are coded.

3. Why would interrater reliability be measured in a quantitative research project?
a. A verbal quantitative questionnaire is filled out.
b. Behavior is observed and classified.
c. Phenomenology is the research method.
d. Distances are measured.

4. What is the purpose of determining an instrument’s internal consistency?
a. It establishes face validity.
b. It demonstrates that the instrument is measuring exactly what the researcher thinks it is
measuring.
c. It decreases measurement error.
d. It is a way of establishing test-retest reliability.
ANS: D
Tests of instrument internal consistency or homogeneity, used primarily with paper-and-
pencil tests or scales, address the correlation of various items within the instrument. The
original approach to determining internal consistency was split-half reliability. This strategy
was a
way of obtaining test-retest reliability without administering the test twice.

5. A new tool and very short tool is developed. It is to be used instead of a previously validated
tool that is very long to administer. What kind of validity concept will be used for testing this
new tool?
