## Midterm
+ Min 43
+ Max 90
+ Mean 75.3
+ Median 77
+ Mode 77
+ Standard Deviation 10.2

## Homework: Midterm Corrections
+ Midterm should not be cram-and-forget
+ Correct the mistakes on your midterms
+ Ask questions for problems you don't understand
???
+ Min 43
+ Max 90
+ Mean 75.3
+ Median 77
+ Mode 77
+ Standard Deviation 10.2
---
## Deliverable
+ GitHub pull request:
+ Question # : Correct answer
+ Open book, notes, everything. Cite sources
+ Have slightly more exposition than the midterm requires
???
## Exposition
+ e.g., if the midterm asks 2 sentences, maybe write 3-4
+ If midterm asks for pseudo code, consider writing Python (though syntax
will not be graded)
---
## Why?
+ These questions frequently come up on interviews and in discussions around
data.
+ "How can you describe a distribution?"
+ "Write out a MapReduce job to calculate click through rates."
+ "How can we tell if a review is duplicated?"
