CPE Data Analysis 3

Question 1

In Backster's scoring system, a score of '-1' on a relevant question indicates:

Accepted Answer

A slight response favoring the relevant question

Answer

A strong deceptive response

Answer

A slight response favoring the comparison question

Answer

No discernible physiological reaction

Question 2

Which analysis method requires a blind examiner to score charts without knowledge of the case facts or prior analysis results?

Accepted Answer

Blind chart analysis

Answer

In-house verification

Answer

Confirmed chart review

Answer

Spot scoring

Question 3

When analyzing electrodermal activity (EDA), what response feature is most significant for scoring comparison versus relevant question reactions?

Accepted Answer

Amplitude and duration of response onset relative to question stimulus

Answer

Baseline skin resistance level

Answer

Total number of spontaneous fluctuations

Answer

Tonic SCL during the inter-question interval

Question 4

During spot analysis, a polygraph examiner compares the physiological response to a relevant question against:

Accepted Answer

The response to the immediately adjacent comparison question

Answer

The examinees resting baseline only

Answer

The average of all relevant question responses

Answer

The response during the pre-test interview

Question 5

What is the primary purpose of calculating 'Total Chart Minutes' (TCM) in polygraph data analysis?

Accepted Answer

To quantify the amount of physiological data available for scoring

Answer

To measure examiner fatigue during the session

Answer

To determine how long the examinee was attached to the instrument

Answer

To track the duration of each individual question

Question 6

When using the Numerical Scoring System, an 'inconclusive' determination is typically rendered when the total score falls within which range?

Accepted Answer

-5 to +5 using a ±6 decision rule

Answer

-5 to -2

Answer

-1 to +5

Answer

+6 to +10

Question 7

Which of the following best describes 'inter-rater reliability' in the context of polygraph data analysis?

Accepted Answer

The degree of agreement between two or more independent examiners scoring the same charts

Answer

The consistency of an examiner's scores across multiple sittings

Answer

The correlation between EDA and cardiovascular channels within a single chart

Answer

The repeatability of physiological responses across multiple test presentations
