What can be done with EDI data?


Aggregate results on developmental health

EDI results for individuals may be aggregated to various levels of complexity, provided the groupings can be categorized in a clear and meaningful way. The useful results that can be aggregated, averaged, and reported include the following:

Compare results among groups

EDI data may be used to show differences between and among groups. For example, EDI data can be used to:

  • Look at gender differences in developmental health (e.g., average scores of boys and girls in EDI domains; percentage of boys and girls who are vulnerable)—which could be presented using statistics and simple graphics.
  • Compare groups across geographic areas—for example, apart from demographic variables (e.g., gender, age), comparisons of children who did or did not participate in a specific program or did or did not attend preschool.
  • Compare average scores and contrast a range of scores across neighbourhoods—for example, two communities may differ slightly in the overall percentage of children who are vulnerable in developmental health, , but a more detailed comparison could show that the percentage range of vulnerable children across neighbourhoods in one community is much wider than that in the other community.

Examine results in association with other societal indicators

Macrolevel aggregations of EDI scores are useful data in association with other societal indicators. For example, EDI data on developmental health could be studied in relation to:
