Gerald says that the most common measurement is 14 quarter inches. is he right? why or why not?

Length of roots in cm        No. of plants
2 cm                                            2
2 1/4 cm                                     0
2 2/4 cm                                     2
2 3/4 cm                                     3
3 cm                                            4
3 1/4 cm                                     4
3 2/4 cm                                     5
3 3/4 cm                                     3
4 cm                                           1

The most common measurement is 3 2/4 cm or 14 quarter centimeters. 

((3*4)+2)/4 = (12+2)/4 = 14/4 or 14 *1/4 cm or 14 quarter cm.

Gerald is wrong because he said 14 quarter INCHES. It should be 14 quarter CENTIMETERS.
