have the error between 10-20%; 17 observations show 20-50% error; while 27 observations have more than 50% error. The following Pie chart shows the distribution of the errors in carrying out
the experiment.
Observations that are more than
ference of the Earth is 40,075 km. Thus, from the observations, it was
inferred that more the distance and bigger the apparatus, the better is the accuracy. Accuracy in observations also depends on precision in making platforms parallel to the ground and precision in making the gnomon perpendicular to the platform.
We would like to thank every mem- ber of the VIPNET club who participat- ed in this experiment, invested their time, and made it a success. In future, we will do many more experiments together, involving more clubs to explore the wonders of science.
80% accurate (i.e., having less than 20% error rate) were only considered for further calculations. If we considered
observations that are more than 90%, then
the circumference of Earth was calculated as 38,446 km (96% correct), whereas if we consider observations which are more than 80% accurate, then the circumference
of Earth was estimated as 37,636 km (94% correct). With modern science observations, we know that the average circum-
