1. Charting Your Client’s Progress

2. SSD Graphs Provide visual feedback about a client’s progress
Allow you to interpret client outcomes effectively and efficiently as you monitor and make decisions about his or her progress

3. Line Graph
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

14. Vertical and Horizontal Axis

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

16. Vertical (Y) Axis
In a line graph a solid vertical line perpendicular to the horizontal axis which starts at the left hand 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

17. Conditions

18. Condition
Environmental arrangement (e.g., baseline or intervention) in effect at a given time in a single-case design (e.g., in an A-B-A-B design there are two conditions, baseline and intervention)

19. Phase
Period of time within a single-case design (e.g., in an A-B-A-B design there are four phases, two baseline and two intervention phases)

20. Condition Change Line
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)

21. Goal Line

22. Goal Line
Dashed line in a single-case design line graph which represents an objective as quantified by the outcome measure and provides a visual aid that can be used to monitor and evaluate client progress
“If you don’t know where you’re going, you might wind up someplace else.”
Yogi Berra

24. Goal Line with Time Frame

25. Data Point

26. Data Point
Intersection of a time period and a numerical value of the measure used to quantify the outcome in a single-case design line graph

27. Data Path

28. Data Path
Solid lines connecting consecutive data points within a condition in a single-case design line graph

29. Homework assignments (●) and grades (○)

30. Homework assignments (●) and grades (○)

31. Data Series
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)
