Which of these would not improve accuracy?  A)Taking a bigger sample size

B)Using a bigger range of the independent variable

C)Using measuring instruments that can read to a greater number of decimal places

D)Remove anomalies

hypothesising or postulating

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
