This week, you will have the opportunity to put your visual analysis skills into practice by conducting a within condition analysis of a set of data. After selecting a study from the options provided, you will provide an explanation of the process that you used to identify the stability, level, and trend of the data in your set. You should refer to the resources provided in your readings to help you calculate the stability envelope and the split middle line of progress for your set of data.
The following articles include graphs that can be used for the purpose of conducting a within condition visual analysis. Once you access the article, review the graphs, select a graph from the article, and conduct a within condition visual analysis of ONE condition within the selected graph. You should not select a condition that has a straight set of data points or has less than five data points.
Effects of behavioral skills training on teachers conducting the recess-to-classroom transition (Smith & Higbee, 2021)
On the utility of within-participant research design when working with patients with neurocognitive disorders (Steingrimsdottir & Arntzen, 2015)
Please respond to the following:
Identify the article, figure number within the article (include page #), and which condition you are analyzing (first baseline, second intervention, etc.).
Calculate the stability envelop of the data set (remember you only need to use the last five data points within a condition).
Calculate the split middle line of progress of the data set (using the full set of data in a condition).
Analyze your data and provide a summary of the stability or variability, and the trend of the data.
Reflect on the process of the analysis. Identify your areas of strength and note any specific challenges that you had with analyzing the data set and explaining the results.

Title: Effects of Behavioral Skills Training on Teachers Conducting the Recess-to-Classroom Transition
Figure: Figure 1, page 634
Condition Analyzed: Demi's second intervention condition (post-training).
Calculating the Stability Envelope
According to Cooper et al. (2020), stability envelopes can be calculated for trended and non-trended data. Stability is defined as 80% of values within ± 25 of the median value within a condition. Then, check if 80% of the points fall within this range.
The data points are 83%, 80%, 94%, 100%, and 100%.
Arrange the data points in ascending order: 80%, 83%, 94%, 98%, 100%.
Median = 94%.
±25% of the Median
25% × 94% is:0.25×94=23.50
94% ± 23.5% = (70.5% and 117.5%)
stability envelope range is from 70.5% to 117.5%.
Because all five data points fall within the stability envelope from 70.5% to 117.5%, the data is therefore considered stable based upon an 80% criterion.
Calculating the Split-Middle Line of Progress
Data Points: 98%, 80...
