Question

When the balls are dropped they produce the rebound heights given below Data: reb hht 1 rb height2rb ht3 Avg rb ht Tennisball 3 ft dp ht 26 28 in 29 in in Rubber Ball 3 ft dp ht in 3 4 in 5 in Results Use the average rb ht to find the deviations, the average deviation and the percent deviation for both data sets. Report average be ht +/- percent deviation for both data sets.

Answer 1

DATE PAGE Tennis ball Reb bt = 28 in Reb bt 2 = 26 in Reb bt 3 29 in 28 +26+ 29 Average Rob bt = 3 20.666 in 28-27.666 0.333 ... 26-27.666... I 1.6.66 ... 3 = 29-22.666 1. 333.. Dey + Dey 2 + Dev3 3 Av.deviationx100, Peacentage deviation = Av. Reb ht 4.01%

foo Rubber ball, Avesage Reb bt Dev 3 AV dev. 23 Percentage deviation = x 100 16.666 7. foo tennis ball, AV Reb ht 27.666t 4:017 in for subbes ball, AV Reb ht= 4 in 16.6667
By finding the difference between each measured value and the average value, the absolute error in measurement is found. The average deviation is the mean of absolute deviations.
