7. Set 1: Shoreline, State, and North Haven This is not a randomized sample. Although some districts are DRG D districts, generalization to a target population is not appropriate.

27. Set 2 and Set 3 follow. These 2 sets use randomized samples from Branford’s DRG (D). Randomization is a powerful statistical technique which permits generalizing results from a relatively small sample to the larger target population.

39. Bar Graphs of Scale Score Percent Change 4 th Generation CMT Scale Scores Percent Change from 2006 to 2009

40. Percentage Change Calculation Example: State Math Average Scale Score 2006 is 252.6 State Math Average Scale Score 2009 is 262.8 Dividing 262.8 by 252.6 results in an approximate percent change of +4% (less than .04 of one percent (.0004) rounding error)

66. Numerical Tabular Data may have hidden in the rows and columns valuable information that sometimes remains “in the shadows.” Data displayed in a variety of graphical modalities may add clarity by showing the Data On The Surface (DOTS). The responsibility of the reader becomes one of connecting the DOTS. Great care was taken to assure the accuracy of the displayed data. Considering the amount of data and the different display formats, some error may be present and as of yet unidentified. If so, the author apologizes for the inaccuracy and will make an attempt to correct the data as soon as possible.
