The following graph is to visualize these differences between Ed-Fi states. On the horizontal axis it shows the number of entities each state uses from the Ed-Fi UDM (Ed-Fi Core APIs) and the number of entities created as state extension are shown on the vertical axis.
The size of bubbles represents the API level extension dependency rate of each state. This rate is calculated by dividing the number of core entities each state uses by the total number of entities they had in their implementation of Ed-Fi model. The median number of extensions among states is calculated as 16 were median number of Ed-Fi API used was 36. As seen in the graph Michigan has the highest extension dependency rate while South Carolina has the smallest. The median extension dependency for these states has been calculated as 37%.
