Messing with Data March 3rd, 2009. My Expectations. “I think you should be more explicit here in step 2.”. The Take-Aways. ?. The Take-Aways. Aggregation - making it meaningful. Dis-Aggregation - making it useful. Triangulation - making it defensible. Let’s start with a simple example.

MyExpectations “I think you should be more explicit here in step 2.”
The Take-Aways Aggregation - making it meaningful Dis-Aggregation - making it useful Triangulation - making it defensible
Let’s start with a simple example First, I start with my question:
Follow-on Questions: * What about NC breweries? * What about ENC breweries?
A little closer to home… What’s up with retention at CCC? Females? Took ACA? Males? Minorities? Non-Traditional? Fall-to-Fall? Nursing? Cosmetology? Fall-to-Spring? Used AS? DL? Applied? Transfer? GOT?
A little closer to home… What’s up with DL at CCC? Do DL students drop as much as traditional/seated students? Related but separate question: Do DL students succeed as much as traditional/seated students? If NO, then what’s going on?
DL @ CCCFA’08 • 270 seated sections • 73% success / 22% failed or withdrew (15% W) • 61 internet sections • 65% success / 33% D, F, WD (16% W) • 15 hybrid sections • 81% success / 18% D, F, WD (9% W)
Grade Distributions (Fall 2008) Aggregation
Dis-Aggregation Computer Literacy - FA ‘08 5 Sections: CIS 110 3-WB; 2-IN • Attrition • IN01: 35% • IN02: 26% • WB03: 17% • WB04: 28% • WB05N: 18%
Dis-Aggregation Computer Literacy - FA ‘08 5 Sections: CIS 110 3-WB; 2-IN
Dis -Aggregation Students in CIS110 - IN02 taking multiple courses
Dis -Aggregation Students in CIS110 - IN02 taking multiple courses
Now, what about Triangulation? Historical Data • FA 08 internet: 61 sections • 33% D, F, WD (16% W) • FA 07 internet: 59 sections; 34% D, F, W • FA 06 internet: 48 sections; 34% D, F, W
Now, what about Triangulation? Historical Data • FA 08 internet: 61 sections; 33% D, F, WD (16% W) • FA 07 internet: 59 sections; 34% D, F, W • FA 06 internet: 48 sections; 34% D, F, W • FA 08 hybrid: 15 sections; 18 % D, F, W • FA 07 hybrid: 22 sections; 16% D, F, W • FA 06 hybrid: 20 sections: 27% D, F, W
Now, what about Triangulation? Nothing wrong with Qualitative Data- Surveys, Evaluations, Focus Groups What do you think about online courses? Where have you succeeded with online? Where have you struggled online courses? Where have you succeeded with this course? Do you prefer Hybrid or Full Internet?

In Sum… • Think about your question(s)…Outcomes? • Where’s the data? • How can you aggregate it for meaning? • How can you dis-aggregate it for usefulness? • How can you triangulate it for validity?
The Important Stuff Was this what you expected? Suggestions for improvement? Would you attend follow-up sessions (on drilling deeper)…(or something else)?
