SPCE 630 Final Exam Questions and
Answers | Latest Update
Visual Analysis


✓ Involves systematic procedures used to evaluate specific data patterns

and evaluates the presence of a functional relation.




What is visual analysis used for?


✓ -Can be used to evaluate data of individuals or small groups depending

on the unit analysis specified in the research question.

✓ -It is a dynamic process in that data are collected repeatedly, graphed as

they are collected and analyzed frequently.

✓ -Visual analysis focuses on analysis of individual data patterns, thereby

facilitating individualization, rather than group -based generalizations.

✓ -Permits discovery of potentially interesting findings that may not be

directly related to the original research question or program objective.




Formative visual analysis


✓ conducted within and across conditions to identify behavior change

during the course of a study




Behavior change

1 | P a g e | G r a d e A + | 2 0 0 2 5

✓ occurs when data patterns in one condition are different from data

patterns in the subsequent, adjacent condition for the same variable(s).




Summative visual analysis


✓ conducted following study completion, across multiple opportunities to

demonstrate behavior change to determine whether a functional relation

exists between the independent variable and the dependent variable.




Adjacent conditions


✓ when data in one condition differ from what is predicted based on the

preceding condition, behavior change is demonstrated




Within condition visual analyses


✓ Conducted to discern patterns within a single condition during a study.

-You should look for stability of data across a minimum of at least 3-5 sessions prior to

changing conditions (beginning with the initial condition, baseline)




Level




1 | P a g e | G r a d e A + | 2 0 0 2 5

✓ Refers to the amount of behavior that occurs, as indicated by the

ordinate scale value. Is often the characteristic of the highest interest for

behavior change, generally described as low, moderate, or high.




Trend


✓ The slope and direction of a data series or th e direction data are moving

over time (increasing, decreasing, or remaining).

-Referred to as accelerating (increasing in ordinate value), decelerating (decreasing in

ordinate value), or zero celerating (data series is parallel to the abscissa).


-Can also be characterized by magnitude, is often described as steep or gradual and paired

with direction.




To increase confidence in functional relations...


✓ Trend and direction and stability should align with hypothesized data

patterns.




Variability


✓ Fluctuation from one data point to the next and is the opposite of

stability.

Can be summarized as the range of data values within a condition or as the percentage of

data points falling within a given stability envelope.

Stability


✓ Predictability and consistency of data values within a condition or lack of

fluctuations in adjacent.




The objective of between conditions visual analysis (conditions analysis)


✓ To identify if behavior change has occurred




Functional relations


✓ Unequivocal demonstrations that an independent variable (intervention)

produced reliable and consistent change in a dependent variable (target

behavior)




Immediacy of change across adjacent conditions


✓ The degree to which behavior change occurs as soon as the intervention

is introduced.




Overlap


✓ Refers to the values of data in one condition that are in the same range

of values of the data in the subsequent adjacent condition.
