When you do an experiment is it important to have all measuring accurate?
It would be pointless doing the experiment and not measuring accurately
Degree of precision?
average +/- the highest minus the lowest value/2 would be the final answer
What is precision measure?
Precision measurement is that which has maximum uncertainity
Explain the illustration of precision and accuracy?
Precision is a measure of how much tolerance your observation has. If you measure time in an experiment as 1.7 +/- .3 seconds, then you are saying that the obervation is anywhere from 1.4 seconds to 2.0 seconds. On the other hand, if you say 1.70 +/- .05 seconds, you state a range of 1.65 seconds to 1.75 seconds. The second observation is more precise than the first. Accuracy is a measure of how correct a measurement is as compared with a standard. If the instrument that measured 1.7 seconds was actually 1.6 seconds, then it would have an accuracy error of .1 seconds. Precision is related to random error. Accuracy is related to systematic error.
What do you call a factor that confuses the result of an experiment?
If there is a factor that confuses the result of an experiment, I would call that a design flaw in the experiment. It might also be an uncontrolled variable.
When precision increases does uncertainty increase or decrease?
I would assume that with am increase in precision there would be an increase in accuracy and less variables. Therefore I would say that there would be a decrease in uncertainty. The more attention to detail the less chance for mistakes.
How can you increase the precision of the double in c?
no you cannot increase the precision of double itself in C
What is concerned with the reproducibility of measurements?
The term repeatability is usd for an experiment realized by a single person.Reproductibility is used for an experiment realized by two or more persons.
If the experiment animals in the chamber were engage in physical activity such as running how would the experiemnet change the result in metabolism experiment?
It would increase heart rate and breathing
What causes the bubble increase in yeast fermentation experiment?
why is it reasonable that, of the three sugars, glucose would result in the most activiity suring the fermentation experiment
Poor precision in scientific measurement may arise from?
poor precision in scientific measurement may arise?
What can help to increase study precision?
Increasing your sample size might help
Which variables affect solubility?
Heat will increase solubility of solids but not for gases, pressure will increase solubility of gases, surface area of solids increases solubility, agitation increases solubility. __________________________________________________________ Well it depends on what experiment you are doing but i say it would be between the independent variable and the dependent variable.
What is an open experiment?
an experiment where the subjects know what is going on. they are not tricked or fooled with any tactics to increase validity such as placebos etc.
Design an experiment that students can perform to verify the prediction that coffee will increase heart rate in daphnia?
desing an experiment that students can perform to verify the prediction that coffee will increase heart rate in daphnia
WHich action would most likely increase the rate of an enzyme-controlled reaction during an experiment?
raising the temperature from 20°C to 30°C
What scientific equipment would most directly help increase the accuracy and decrease the bias in an experiment?
For example is a pH-meter.
