To determine a distance by Pacing

Can you help me with this, I just need sample so, I can follow how to do this. Thank you

1. B) To determine a distance by Pacing

Procedures:

1. Establish the end points of another level course and mark it C and D. The distance of CD is to be determined by pacing.
2. Start walking on a straight line over the course at a natural pace from point C to point D.
3. Repeat procedure No. 2 until five trials are completed. Tabulate the results.

DATA:

.

1. Compute the mean number of paces and write it in column 4 of the above table.

1. Compute the paced distance.

Paced distance = mean x pace factor (previously determined in objective A).

Write the result in column 5 of the above table.

1. After the field data is recorded (above table) make an actual taping of line CD by using the tape. In our data, the tape distance was recorded to be 61m (column 6). This is the measured length of line CD using the tape.

1. As you will notice, there is a discrepancy between the taped distance of line CD and the paced distance of line This discrepancy is called error.

1. Determine the error.

Error = taped distance – paced distance

1. Compute the relative precision. Relative precision refers to the accuracy of the measurement. It is the ratio between the error to actual distance of the line. The actual distance is he taped distance.

From the above computed data:

Relative precision  =    

             *Note: Reduce the numerator to unity so that relative precision will the form of

                (e.g.    )

                    This means that the error of our measurement is 1 meter for every 1500 meter.

                     You can do it by dividing the numerator by itself and dividing the denominator by            

                     the numerator.

10. Tabulate the result in the last column.
