Percent error is a statistical tool used for evaluating precision. It is expressed as:
Percent error = | (experimental value - theoretical value) / theoretical value | x 100%
Experimental value represents the calculated value while the theoretical value represents the known value. A percent error value which is approaching zero means that your experimental value is close to the known value. Which can possibly mean that you have precise measurements. Calculations are as follows:
Percent Error = | (2.54 - 2.70) / 2.70 | x 100 =5.93%
Thus, the answer is b. 5.93%.
Balance improves
Balance is the ability to maintain a controlled body position during performance of task. Age appropriate balance and coordination allows the child to be involved in the sports participation with a reasonable degree of success as it helps the body fluid movement for physical skill performance. <em />With good balance and posture injury and fall can be prevented. This can also help maintain appropriate controlled body movement.
