  1. Calculate the percent error if the true value and observed value are 60 and 35 respectively.


    Step 1 :  

    The given parameters are

    True value=60 and observed value=35



    Step 2 :  


    The percent can be calculated using the equation,


    Percent Error=$\frac{True\ value-observed\ value}{True\ value}$$\times$ 100


    Percent Error=$\frac{60-35}{60}$$\times$ 100


    Percent Error=41.66%



    Answer  :  

    Percent Error is given as,

     

    Percent Error=41.66%



  2. Determine the percent error if the true value and observed value are 100 and 90 respectively.


    Step 1 :  

    The given parameters are

    True value=100 and observed value=90



    Step 2 :  

    The percent can be calculated using the equation,


    Percent Error=$\frac{True\ value-observed\ value}{True\ value}$$\times$ 100


    Percent Error=$\frac{100-90}{100}$$\times$ 100


    Percent Error=10%



    Answer  :  

    Percent Error is given as,

    Percent Error=10%
