Flashcards in Chapter 5 Deck (22):
1

Which IOA is recommended for behaviors that occur at relatively low frequencies?

scored interval IOA

2

Which IOA overestimates agreement?

interval by interval IOA

3

Calibration

any procedure used to evaluate the accuracy of a measurement system and, when sources of error are found, to use that information to correct or improve the measurement system

4

Reliability

describes the extent to which a measurement procedure yields the same value when brought into repeated contact with the same state of nature (consistent measurement)

5

Accuracy

in terms of measurement, it is the degree to which it corresponds to the true value of the thing being measured

6

Convention for acceptable IOA

80%

7

Discontinuous measurement

measurement conducted in a manner such that some instances of the response class of interest may not be detected

8

Measurement bias

nonrandom measurement error (error in measurement that is likely to be in one direction)

9

Indirect measurement

occurs when the behavior that is measured is in some way different from the behavior of interest. considered to be less valid.

10

DIrect measurement

occurs when the behavior that is measured is the same as the behavior that is the focus of the investigation.

11

What is a more conservative/meaningful assessment of IOA?

mean duration per occurrence

12

The most stringent IOA for most data sets obtained by event recording?

exact count per interval IOA

13

Total duration IOA is computed by?

shorter of two durations reported by the observers/the longer duration

14

3 techniques commonly used to calculate IOA for interval data

interval by interval IOA, scored interval IOA, unscored IOA

15

Most common convention for reporting IOA

percentage of agreement between observers

16

IOA recommended for behavior that occurs at relatively high frequencies

unscored-interval IOA

17

Continuous measurement

measurement conducted in a manner such that all instances of the response classes of interest are detected during the observation period

18

Observer reactivity

measurement error resulting from an observer's awareness that others are evaluating the data he reports

19

Naive observer

a trained observer who is unaware of the study's purpose and/or the experimental conditions in effect during a given phase or observation period

20

Observed value

what is seen; quantitative label produced by measuring an event

21

True value

measurement that yields data that are directly relevant to the phenomenon measured and to the reasons for measuring it

22

Observer drift

unintended changes in the way data are collected - may produce measurement error
