This will help them maximize their winnings and make the most out of their bets. Moreover, the sgp prize data that we provide is free to use and available to all. This means that a bettor can access the sgp prize data even if they do not have an internet connection.
The SGP system utilizes longitudinal student data to produce statistical growth plots (SGPs). SGPs are graphical displays of students’ standardized test score histories that depict how they rank in relation to peers with similar prior achievement levels. SGPs can be more useful and meaningful than unadjusted tests scores because they offer a more holistic picture of student achievement.
In addition to displaying student progress in percentiles, SGPs can also display the likelihood that a student will reach proficiency within a given time frame, depending on their current performance level and projected growth trajectory. To generate these projections, SGPs analyze the history of students’ standardized test scores and determine what additional scores are required to meet or exceed a proficient standard. SGPs are updated periodically, ensuring that the student growth predictions are based on the most recent data available.
When using SGPs to predict student proficiency, you can choose a specific window of time in which to project student growth by selecting a previous or current school year during report customization (in the Timeframe drop-down list). SGPs are based on historical student performance so that your projections will not be affected by changes in student demographics.
While the SGP project is focused on the development and maintenance of a permanent repository of data, our goal is to facilitate access to significant portions of this dataset that would not otherwise be accessible without an incentive for collaborative research projects. We are able to provide researchers with access to legacy and unpublished data through the SGP database as well as through guest instruments at our Central Facility located southeast of Lamont, Oklahoma.
There are two common formats for representing longitudinal student data: WIDE and LONG format. The SGPdata package installed when one installs the SGP package includes exemplar WIDE and LONG data sets (sgpData and sgpData_LONG, respectively) to assist in setting up your data for running SGP analyses. The SGP package includes wrapper functions prepareSGP and updateSGP that combine these steps into a single function call, simplifying the source code associated with operational SGP analyses.
