A lot of people are confused about the meaning of data sgp. They think that it is a database of information about the students in a school district. But the truth is that this is not the case. Data sgp actually refers to a specific process of using the student growth prediction model. The SGPT process is designed to help schools analyze current student assessment results and predict how much progress each student is likely to make over time. The purpose of this article is to explain the meaning of data sgp and how it can be used in the SGPT process.
The sgpData data set is an anonymized panel data set of assessment results in LONG format from 8 windows (3 windows annually) across 3 content areas (Early Literacy, Math, and Reading). The first five columns, ID, GRADE_2013, GRADE_2014, GRADE_2015, and GRADE_2016, provide the unique student identifier, the grade level at which the student was assessed during each year, and the scale score that was associated with each assessment result for that year. The final 5 columns, SS_2013, SS_2014, SS_2015, SS_2016, and SS_2017, provide the scale scores associated with each student in each of the previous 5 years.
sgptData_LONG is a slightly different set of data than sgpData, in that it includes demographic/student categorization variables as well. It also contains 5 additional columns: DATE, VALID_CASE, CONTENT_AREA, YEAR, and SCALE_SCORE, which are used by the sgptData function to create aggregates of student data for various analyses, including student growth projections.
In general, using wide-format data with the SGP package is straight forward. However, there are some important considerations when analyzing this type of data that should be taken into account. Please consult the SGP data analysis vignette for more detailed information on using data sets like sgpData and other wide-format data with the SGP package. In addition, a more comprehensive documentation of the use of sgpData and the SGP package is available on the SGP website. The SGP vignette is also an excellent reference for creating your own custom analysis scripts to get the most out of the SGP package.
