Question

Analysis for a measured quantity Let's say, in the 'Free fall motion experiment', you measured the acceleration due to gravity four different times and recorded the data into Table 1. Table 1: four successive measurement of the acceleration duo to gravity g Answer the questions below to analyze the data Calculate the average value of the measured accelerations. Calculate the mean absolute deviation. Describe your experimental result in the standard form* using the results of 4 1 and 4.2. Calculate the percent error. Calculate the percent difference of the acceleration between the average value and its standard value g = 9.80 ms^2 Compare the percent difference to the percent error, and discuss if the measured value of g is consistent with the standard value Standard form means. (the measured physical quantity) = (the mean value) + (the mean absolute deviation)

Explanation / Answer

1. the average value of the mesasure acceleration is 9.77m/s

9.80+9.68+9.88+9.72 =    39.08/4 =   9.77m/s

2. the mean abslolute deviation is 0.07m/s

9.80-977= 0.03    9.68-9.77=-0.09     9.88-9.77=0.11   9.72-9.77=-0.05  

0.03+0.09+0.11+0.05 = 0.28 / 4 = 0.07
