Flashcards in Interpreting Data Deck (33):
What are three purposes of graphs?
Communicate the data
Assess data correctly
I/D- IV/DV: Shows how IV and DV are realted
What are five types of graphs in ABA?
Scemilograrthighmic- Standard Celeration
Equal Interval Graphs are AKA
Arithmetic Charts, Add-Subtract charts
What is an equal interval graph?
The intervals are all equal
What are four types of equal interval graphs?
scatterplot, line, bar and cumulative record
What are non-equal interval charts?
Line graphs are AKA
What are the most common graphs in ABA?
When should you use a line graph?
When you want the data to effectivley communicate data the is scaled along some dimension
What are the seven parts of a line graph?
Condition change lines
When are times that data points should NOT be connected?
When there has been a break in time, but no data collected. Across phase change lines, Follow up, post check data.
Bar graphs are AKA
What is a Cartesian Plane?
2- dimensional area formed by 2 perpendicular lines that intersect
When do you use bar graphs?
When you want to represent data that are not related to one another.
What is a downside of bar graphs?
They do not allow for the analysis of variability and trend . They can also not be used with time
Who developed the Cumulative record?
BF Skinner, 1957
What is a cumulative record?
Keep adding on responses, it never goes down in trend. They are generally used for rate or frequency
What are two types of cumulative Record?
1. Overall Response Rate
2. Local Response Rate
What is Overall Response Rate Cumulative Record?
An average rate of response over a given time period.
Divide the total number of responses recorded by the number of observation periods.
What is Local Response Rate Cumulative Record?
Rate of response during a time smaller than than for which an overall response rate has been given.
What is a semilogarithmic graph?
Graphs in which ONE axis is scaled proportionally
Why would you use standard celebration?
When you are looking at rate of responding.
What do data points look like in a scatter plot?
How should you display your data, graphically speaking?
In the most valid way possible. You need to display your data in a way that appropriately represents the behavior and the data.
What are the three fundamental properties of behavior change?
Level, trend and variability
What is the level of a graph?
It is depicted as flat or level line in a graph.
Value on the vertical axis.
What does a change in level mean?
The datas average value changes
How do you find the level?
Examine the mean, median and range.
What is the mean level line?
A horizontal line drawn through the data points on the vertical axis which is the average or mean of the data.
What is the median level line?
Horizontal line drawn through the data points on the vertical axis. Calculate the median of the data points.
Better option than mean level line if you have outliers
What is trend?
The overall direction of the data. It can increase, decrease, zero. It can be gradual or steep. It is a straight line through the middle of the data.
How do you make a trend line?
Count, divide, mid rate, mid date, quarter and split
