Question

Four students all do the same experiment for the science fair. They test reaction times for pushing a button when a specific color is shown. Their data is as follows:
⎡⎣⎢⎢⎢⎢⎢⎢⎢⎢Student 1Student 2Student 3Student 4Reaction Time (seconds)Trial 10.440.350.410.42Trial 20.410.430.520.43Trial 30.470.380.570.41Trial 40.390.390.460.42Trial 50.460.420.550.41Trial 60.420.440.490.42⎤⎦⎥⎥⎥⎥⎥⎥⎥⎥
[
Reaction Time(seconds) Trial 1 Trial 2 Trial 3 Trial 4 Trial 5 Trial 6 Student 1 0.44 0.41 0.47 0.39 0.46 0.42 Student 2 0.35 0.43 0.38 0.39 0.42 0.44 Student 3 0.41 0.52 0.57 0.46 0.55 0.49 Student 4 0.42 0.43 0.41 0.42 0.41 0.42

Put the students in order from most to least reliable data.

A. Student 1, Student 2, Student 3, Student 4
B. Student 4, Student 1, Student 2, Student 3
C. Student 2, Student 1, Student 4, Student 3
D. Student 3, Student 2, Student 1, Student 4

Answer 1

Sorry, Cant really tell how to differentiate the students and trial times
