Exploring Scores
X Step 1: Load both data sets into “data frames”
X Step 2: Show a summary of the data just read
X Step 3: Histogram of the score_1 column ofscores.csv
X Step 4: Evolution of student scores

Exploring Events
X Step 5: Add 5 more columns to the eventdata-frame. Value “1” if event of certain type.
X Step 6: Count the events of each type andaggregate for each user
X Step 7: Merge previous columns with scorefactors. The result has 14 factors (9 scores +5 with number of events).
Can you predict anything?

Exploring data sets
X Do you have an idea about the type of factscollected?
X Is there any new information you discovered?

Potential predictions and interventions
X Which factor (present or new) would you liketo predict?
X What kind of intervention would it prompt?
