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
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
experiments
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
experimental results
Experimental Results

The following scaled GRE scoreresults were collected

i1=represents failing/negative test

i2 =represents passing/positive test

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

  • 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.

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.

conclusion
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 children’s books. Therefore there is no chance that OSU undergraduates will pass the GRE.
