Question

Fransisco and kazuko guess the number of marbles in a jar. Fransisco guesses 50 marbles and kazuko guesses 60. The actual number of marbles is 55. Kazuko says there is less error in her guess because 50/50=10% and 5/60= 8.3%. Explain why kazuko is incorrect

Answer 1

The difference in both the guessed values is 5 unit

Explanation:

The less error computation is done by dividing the difference between the guessed value and the actual value.

Here in this case

Error in case of Fransisco = 55-50 = 5

Error in case of Kazuko = 60 -55 = 5

Hence, both have guessed incorrect value and their incorrect values is either 5 units less or 5 units higher than the actual value.
