Student Data from SimRocket

NOTE: This data was reconstructed from the video tapes. Some data is still missing. The section called "averages" was computed by spreadsheet from this data. The section called "students'" contains the figures computed by the students as reconstructed from the video tapes. The prediction for the height of Rocket #8 is computed below using each set of figures:

Student computations:

rounded nosecone better than pointed by R1 – R2 = 372.95 – 353.65 = 19.3

3 fins better than 4 fins by R3 – R4 = 384.9 – 370.5 = 14.4

painted body better than sanded by R6 – R5 = 282.5 – 271.75  = 10.75

Big Bertha engine better than Giant Gamma engine by R1 – R7 = 372.95 – 312.15 = 60.8

R8 = R1 + pointed + 4 fins + painted = 372.95 – 19.3 – 14.4 + 10.75 – 60.8 = 289.20 vs. 299.75

Spreadsheet computations:

rounded nosecone better than pointed by R1 – R2 = 372.92 – 353.67 = 19.25

3 fins better than 4 fins by R3 – R4 = 384.92 – 370.50 = 14.42

painted body better than sanded by R6 – R5 = 276.92 – 271.21  = 5.71

Big Bertha engine better than Giant Gamma engine by R1 – R7 = 372.92 – 320.25 = 52.67

R8 = R1 + pointed + 4 fins + painted = 372.92 – 19.25 – 14.42 + 5.71 - 52.67 = 292.29 vs. 301.50
