Chapter 5 Flashcards

graph that connects successive data points (e.g., status of an outcome at a particular time) with lines to show changes in the value of a variable (e.g., client outcomes), usually over time Line graph

in a line graph, a solid horizontal line perpendicular to the vertical axis that represents, from left to right, the chronological progression of equal time periods (week 1, 2, 3, etc.) or other units (e.g., intervention sessions) Horizontal axis (X-axis)

in a line graph, a solid vertical line perpendicular to the horizontal axis that starts at the left end of the horizontal axis, and represents a range of numerical values of the outcome measure with equal intervals representing equal quantities and lower to higher values arranged from bottom to top Vertical axis (Y-axis)

environmental arrangement (e.g., baseline or intervention) in effect at a given time in a single-case design Condition

period of time within a single-case design Phase

dashed vertical line drawn upward from the horizontal axis on a single-case design line graph that shows the point when a change is made from one condition (e.g., baseline) to the next (e.g., intervention) Condition change line

dashed line in a single-case design line graph that represents an objective as quantified by the outcome measure and provides a visual aid that can be used to monitor and evaluate client progress Goal line

intersection of a time period and a numerical value of the measure used to quantify the outcome in a single-case design line graph Data point

solid lines connecting consecutive data points within a condition in a single-case design line graph Data path

set of related data points plotted on a single- case design line graph (e.g., data for one outcome, such as percentage completed assignments, or data from one source, such as a single teacher) Data series
