Systematic error

(0,0), however the graph passes though (0,0.069) which is very close. It may be that the relationship is directly proportional and that the small difference is due to systematic errors in the practical. Errors Random errors: A random error is an error in which its effect on measurements vary in each trial. Hence this type of error has an effect on the precision of data. Precision is how close together a set of measurements are regardless of how far away they are from the true value.…

This is the reason behind the identical values observed, and was predicted with the aid of the theoretical proof. Firstly, several errors related to the air hockey table were observed. Primarily, there was the possibility of inconsistent pressure regions on the air hockey table. It is likely that there were regions on the table with high pressure and low pressure regions, which would…

have to take into consideration that the mass of the boat is combined with the mass of the drops. However, we are measuring the combined weight of both and therefore there is no need to measure the mass of the boat by itself. The major possible error is that…

In the past health care was more of a systematic process that was rigid and tightly monitored leaving very little room for error because everything was done by hand, double and sometimes tripled check before a process begun. At that time, most deaths resulted from unformulated systems that were still being invented on how to save a life or to cure a disease. The way physician handled patient care uncertainties was with an open culture by being transparent to the patient’s their families. The…

source of systematic error is parallax error. It is highly likely that measuring the length of the tube was affected by the positioning of the ruler against the tube as well as the eye against the ruler. The absence of millimetre measurements on the ruler also required the observer to estimate to the nearest millimetre which also likely resulted in inaccuracies. The mouth of the tube was also rigid which has possibly had an effect on the end correction value of 0.4d, however this error is simply…

that pH 7 should have the highest enzyme activity. In every experiment, there are random and systematic errors. A possible systematic error might be that the scales are faulty and did not give accurate measurements of the weight, thus making the results unreliable. A systematic error that did occur was the pH concentrations were not close enough to what they were labelled to be, 3, 5, 7, and 9. A random error that may have occurred was when measuring the meniscus of the pH levels, might have…

optimum peak at the pH of 7. However, in consideration of both the error bars and the p values taken from the t-test, there were some inconsistencies between different trials of the same pH as well as inconsistencies between experimental values and theoretical values. This may have been as a result of the presence of both systematic and random errors during the conduction of the experiment. It was suggested that the main systematic error during the investigation was the presence of smaller sized…

cylinder and making sure the water level is read by the bottom of the meniscus will help with the water accuracy. A random error that occurred throughout this practical was a different reaction time of when to drop in the Alka-Seltzer and start/stop the stopwatch. This error may have also impacted on the timing of how long it took the Alka-Seltzer. A way to prevent this error could be to set up each trial one at a time. It is important with every experiment to have at least a minimum of three…
