Questions

3. Data Mining Defined
The process of examining large amounts of data to generate new information
Answer questions
Explain changes
Establish patterns

4. Data Mining How to data mine? No single answer
Dig into data, looking for
Oddities/unusual results
Patterns you haven’t seen before
Breaks in existing patterns
Always looking for ‘Why?’
Goal of data mining is to better understand the data you have, so you can make better inferences from it.
Example: GRPS 9th Grade elevated enrollment - Don’t fully explain
Ask group: What would you do to try to figure that out?
Explain
Example: 2005 demand from Superintendent – Each school to enroll 10 new students (80 schools)
Principals all produced lists of new student in their schools, District enrollment still down.
How would you data mine that?
Most of this session, is giving you tools and techniques for data mining, take through some examples.

5. Data Mining Sources of Data Your SIS CEPI submission downloads
MiSchoolData
Other sources

6. Sources of Data Your SIS Details not captured any other place
Attendance details
Historical data
Discipline data not meeting reporting threshold
Other?
Home address mapped out (bus routing system) – Boundary dispute between two schools about a line with no kids living there.

7. Sources of Data CEPI Submission Downloads
Files submitted and edited during submission process
NOT just submitted files
CEPI staging area
CEPI clears staging area annually

8. Sources of Data CEPI MSDS login https://cepi.state.mi.us/msds/
Discuss FTE reports – Can pull anyone's FTE report

9. Sources of Data MiSchoolData Site maintained by CEPI
Public AND Private data
Primarily summarized, charted data

10. Sources of Data MiSchoolData login https://www.mischooldata.org/
Sample problems: #1
High school enrollment dropped at GRPS in 2003/04, but came back up a year later. can you figure out why?
Look at 2004/05, all grades comparison, trend
#2:
It’s spring on 2013/14 at GRPS, and my Superintendent wants to know if I can accurately predict how many residents will go to other Districts next year. Can I? How? Would I have been right?
Look at Non-resident Status in 13/14 for whole District K-12, all non-resident reasons, trend.
Then shift to 14/15 to see if I was right.
Emphasize “Data files” under “Other Data”

11. Sources of Data Other sources?
What other sources of data have you used? Where do you go to get data?

12. Data Mining Tools XML editors
Best for opening, reviewing specific data
Not really data extraction tool

13. XML Editors XML editors XML Notepad Notepad ++ Free applications
Simple interface

14. XML Editors

16. XML Editors
(open sample file in XML Notepad)

17. Working with MS Access MS Access Powerful database program
Easy to create queries, reports
Not included in all versions of MS Office
Steeper learning curve that Excel
How many use Access? Do you like it? Thoughts for those not into it yet?

18. MS Access (open sample file in MS Access) Data Mining.accdb
Explain structure - tables, queries, forms, reports
Explain sample data tables
Stucourse – Open and work with
Add numbergrade and comp status
Compute average GPA by course
Compute same for 9th grade only
Percent failed by teacher
Excel exporter

19. MS Access Testcnt: iif([field being evaluated]=“test condition”,1,0)
“Sum” in Total row

20. MS Access Failcnt: iif([comp status]=“failed condition”,0,1)
“Sum” in Total row

21. Working with MS Excel Excel Spreadsheet program Easy to use
Pivot tables – Very powerful
As powerful as Access, easier to use
How many use Excel? Do you like it? Thoughts for those not into it yet?
How many have used Pivot tables?
How many are scared of pivot tables?
