Discovering why OSU students have the lowest
national GRE scores

• By David Hines
• Stephen Kerns

2
Motivation

• Dean Buck has been reviewing OSU GRE scores and
  noticed that they are well below average, and
  much lower than their northern rival
• Based on www.ets.org statistics from 2003-2006

What is wrong with OSU Students

• After speaking with leading scientist, Dean Buck
  thought there are 3 possible reasons
• Students are genetically stupid
• Students drink to much and therefore have no
  brain cells
• Students never learned to read

4
Experiments

• To test his three hypothesis the following tests
  were conducted on 3 different groups of OSU
  students
• A blood assay to determine the presence of the M
  intelligence gene
• CT scan to determine active brain cells
• Asked each student to read Go Dog Go

5
Experimental Results

• The following scaled GRE scoreresults were
  collected
• i1represents failing/negative test
• i2 represents passing/positive test

6
Yates Algorithm Solution

• Create table with experiments listed in specific
  Yates Algorithm order in first column and Totals
  listed in second column.

7
Yates Algorithm Solution (contd)

• For the next column add the pairs of rows in the
  first column to obtain the first four rows and
  subtract the same pairs to obtain the next four
  rows.

8
Yate Algorithm (contd)

• Repeat for the number of factors (i.e. fill out
  the 3rd 4th columns in the same fashion as the
  2nd). Ignoring the 1st row, the highest value in
  the final column indicates the row with the
  combination of levels of the factors with the
  strongest effect.

9
Conclusion

• Dean Buck wept for many moons as he came to the
  realization that OSU students are genetically
  inferior and never learned the proper skills to
  read even the simplest of childrens books.
  Therefore there is no chance that OSU
  undergraduates will pass the GRE.
