Answer: The possible source of error in this activity is " the accuracy of making and recording measurements"
The height of each and every student in the class has to be taken very accurately. Even if there was a single error in either making the calculation or even recording it, the average height will take a hit and will result in the entire exercise being a failure.
Hence, it’s very important to accurately measure the height and record and even have a second person do the same activity so that the numbers recorded are accurate.
