Is A Picture Worth A Thousand Numbers? An Exploration Of Understanding And Recall Of Data Presentations, Holly L. Roof
Electronic Theses and Dissertations
This dissertation reports results of a study with a quasi-randomized experimental component and a protocol analysis, or think aloud, component. The experimental component was designed to determine if people with no statistical training and people with some statistical training differed in their understanding and recollection of statistical information with varying degrees of complexity. Information was presented using data visualization techniques based on cognitive theory and compared to presentations using APA-style numerical tables of statistical output. The focus was on using empirically-supported graphical displays in PowerPoint presentations such as one might see at a research conference. Classroom groups of beginning and …
Latent Growth Curve And Latent Change Score Modeling Of Developmental Relationships Between Executive Functioning And Math Achievement In Early Elementary School, Kerry-Ann Lewis Pearcy
Latent Growth Curve And Latent Change Score Modeling Of Developmental Relationships Between Executive Functioning And Math Achievement In Early Elementary School, Kerry-Ann Lewis Pearcy
Electronic Theses and Dissertations
The current study compared latent growth curve (LGC) models and latent change score (LCS) models capabilities in modeling complex data in a development framework. Using the nationally representative ECLS-K:2011 dataset, LGC and LCS models explored the dynamic relationship between executive function and math achievement. The relationship between the two constructs has been extensively examined but little is understood about their dynamic relationship. The findings of this study indicated LCS to be more robust than LGC in modeling complex data and in examining dynamic relationship. The findings also suggested that one of the two executive functioning tasks, Dimensional Change Card Sort …
