Field Methods Lesson 3

Type of construct validity that is demonstrated by a strong relationship between the scores obtained from two (or more) different methods of measuring the same construct.

• Convergent Validity

• Discriminant Validity

• Criterion Validity

• Content Validity

Which modality of measurement is the most objective?

• Physiological Measures

• Self-Reported Measures

• Behavioral Observations

• Qualitative Interviews

This graph shows the amount of consistency between two different measurements, the two scores being represented as a single point.

• Bar Chart

• Line Graph

• Scatter Plot

• Pie Chart

The clustering of scores at the low end of a measurement scale, allowing little or no possibility of decreases in value.

• Ceiling Effect

• Floor Effect

• Normal Distribution

• Skewed Distribution

Participants have identified the hypothesis of the study and are trying to act contrary to the investigator’s hypothesis.

• Negativistic Subject Role

• Conformity Bias

• Experimental Control

• Observer Effect

Participants attempt to follow instructions to the letter and avoid acting on any suspicions they have about the purpose of the study.

• Faithful Subject Role

• Skeptical Participant Role

• Passive Observer Role

• Inquisitive Subject Role

A measurement of reliability in which different versions of the instrument are used for the test and the retest.

• Test-Retest Reliability

• Internal Consistency

• Parallel-Forms Reliability

• Split-Half Reliability

It specifies a measurement procedure for measuring external, observable behavior and uses the resulting measurements as a definition and a measurement of the hypothetical construct.

• Operational Definition

• Conceptual Framework

• Theoretical Model

• Empirical Evidence

Scale:

It tells us the direction of the difference (which is more, and which is less).

• Ordinal Scale

• Nominal Scale

• Interval Scale

• Ratio Scale

This validity examines whether a measure is positively related to other measures of the same or similar constructs.

• Convergent Validity

• Discriminant Validity

• Criterion Validity

• Face Validity
