GINO DEZIRE NEAL MEASUREMENT 1 357.4 MEASUREMENT 2 339.6 MEASUREMENT 3346.2 MEASUREMENT 4349.2 348.1 322.6 324.7 323.5 326.9 324.4 1.61 0.93 340.6 347.6 345.8 342.6 344.15 2.72 1.57 MEAN STANDARD DEVIATION STANDARD ERROR 3.69 6.39 Assume the true value of the speed of sound in air at 25 C is 346.5 m/s. Three students name Gino, Dezire and Neal made the following measurements (in m.s) of the speed of sound in air at 20°C. Comment on the accuracy and precision of each student's measurements and indicate which students (if any) seem to have a systematic error a). which student is the most accurate? Why? b.) Which student is the most precise? Why? c.) Which student has a systematic error in his/her measurements? Why?Explanation / Answer
a) Student Gino is most accurate as Mean value of gino is most close to the true value of speed of sound.
b) Student Dezire is most precise than others because the its measurent vaues has minimum variations as we can see through deviation also.
c)Student Dezire has systematic error because he is the most precise one but his error is very high. this can be possible because of systematic error.
