Data sgp is an analysis tool for longitudinal student assessment data that creates statistical growth plots (SGPs) which provide visual evidence of student progress relative to academic peers. SGPs are created by combining students’ standardized test scores with covariate information using an established “growth standard”, determined through prior testing history. This approach is more accurate than traditional percentile scores in assessing students’ performance. SGPs can also help educators and administrators better understand a student’s strengths and weaknesses and target specific areas of improvement.
SGP is a new generation of statistics software designed to assemble and analyze enormous datasets that would overwhelm conventional relational database applications. Although it is often referred to as “big data” it does not reach the size and complexity of many modern applications of this term, such as analyses of global Facebook interactions. This is why the SGP software has been developed as a streamlined, easy to use relational application that works with the data you have in your hands, rather than trying to impose an artificial, esoteric structure on it.
As a result, the SGP user interface is simple and intuitive, with a familiar set of buttons and menus for common functions such as importing the data and performing basic operations such as calculating percentiles. The software is also designed to work efficiently with long formatted data files, leveraging embedded SGPstateData meta-data in the sgpData_LONG formatted data sets for faster and more accurate calculations. Higher level SGP functions have been tailored to take advantage of the extra space provided by the sgpData_LONG formats, enabling them to perform complex calculations that would be difficult or impossible with short formatted data.
In addition to providing a consolidated view of student performance, the SGP software provides a series of reports that allow users to easily compare the results from multiple schools or districts. The reports can be used by teachers and administrators to identify trends in student performance, as well as to determine which schools/districts are making the most progress in a given area. These reports are also useful for assessing the effectiveness of a particular program, school or teacher and making adjustments as necessary. Lastly, SGP can also be used to identify gaps in student achievement and make strategic decisions regarding student support and intervention. This is especially valuable for identifying at-risk students and targeting services to meet their needs.
