By using colorimeter and have standard to compare it to
Why repeating helps in reliability
To spot anomalous results n to calculate average
…….states clearly what is being investigated
title
……is often extended to a prediction for the particular experiment
hypothesis
…… is an honest assessment of • the limitations of the procedure
evaluation
……….is usually done by identifying by a number the place in the report where other work has been used
acknowledgement
