Here’s a quick summary of what we discussed in class: We’ll have (at least) two dashboards both based on the same underlying pool of data. Dashboard 1 is just one graph with three (or more) lines on it showing retention, persistence, and persistence to graduation rates
By Tuesday, use index cards to sketch out charts (and take notes about questions/problems) for the two dashboards.
Dashboard 1: Overall Line Chart
A line chart with three lines: current year, one year back, two years back. The line chart covers six full years so the user can see retention (student completed first year), persistence (completed years two through six), and persistence to graduation (student actually graduated in six years).
The user should be able to determine what categories are used for that data (see the Dashboard 2 categories on the Resources page), based on the long list of categories (ethnicity, first-year, gender, etc.). So in addition to the dashboard the user will need some way to select the categories (and—see below—possible combinations).
They’ll probably need to be able to combine categories on the line charts (e.g., gender + international student, which will have four possible values (male + international, male + non-international, female + international, female + non-international).
Questions: Are there categories that won’t fit easily onto this format? How many lines can we show on the chart and still have it be readable—the gender + international example above would have 12 lines on it (four possible values x 3 years)?
Dashboard 2: Six Categories on One Dashboard
The second dashboard would let the user select up to six categories from the long list Cathy described. Each of the six charts would show resistance, persistence, and persistence through graduation for that category. The KPI would be current year with a text label showing if that rate is below or above the previous year. Most of the charts would be KPIs, but some categories might not work well. If we need more info about the category, note that so we can ask for more info.
Questions: What categories won’t work as KPIs? Will another format work for those? Would we allow users to click somewhere on a chart to enlarge that chart (possibly show all 12-15 charts in very small size and allow the user to click one to zoom in)?
