Cumulative record
- NEVER shows decreasing data, always goes up
- zero-rate of response on cumulative record is a flat line-horizontal. No new responses have been added/observed #flatzero
- increasing trend line on a cumulative record shows that there is responding occuring. #increasingresponse
- A steeper slope : an increasing rate of responding. = more rapid responses.
- a flatter slope : responding is slowing down/decreasing
- are used when a target behavior can be measured in cumulative units, when the total responses over a period of time is important
- is an equal interval graph, rate/frequency data as it collects a cumulative amount of responses over time = rate
- the most important consideration when analyzing a cumulative record is the steepness of the slope, this tells us how fast or slow the response rate is of a behavior #responserate
- is most appropriate when the target behavior occurs once per observation period, this kind of graph shows the number of responses accumulation over time and how the rate of responding changes.
Minor Condition changes in the independent variable(#intervention) of a program
- should be displayed using a DOTTED condition change line
Major condition changes ing the independent variable(#intervention) of a program
- should be displayed using SOLID condition change line
Display on Graph
- The measurement of the behavior(#dependetvariable) should always be plotted on the y-axis(e.g. duration).
- The observation period(#indepedndentvariable) shoule always be plotted on the x-axis(e.g. running occurrence number).
- you should also ensure that your selected observaion periods and measurement systems align with your graph
- the vertical axis(Y-axis) should be approximately 5/8 the length of the hrozontal axis(X-axis)
Data points should be connected when they are:
- in the same phase,
- with no scale breaks between them,
- when they show consecutive,
- continuous observation
If they are seperated by consition change lines,
- there is a discontinutiy of time on x-aix,
- there was lost data,
- or data was not collected after time passed then wo do not connect them
Reflect instances of property destruction per day(kind of rate)
: standard celeration chart, line graph, equal interval graph
- no cumulative graph, no bar graph, no scatter flot
Reflect sucessive measurements of behavior across time
: line graph, equal interval graph, cumulative record.
Bar Graph
- to display data that are UNRELATED to each other(i.e. different categories of data)
- Bar graphs do NOT dispaly data trends or variability in data, they only display the levels of data.
Line Graph
- are used to analyze the relationship between data scaled on the same dimention(e.g. comparing percentage to percentage)
Celeration Chart
- the change of the rate od a response over time is displayed on.
