Why is it better to align the meterstick with edge of the object at the 1 cm mark rather than at the end of the stick?
meter sticks give precise measurements and in order to get the full precise answer you should start where the numbers start at on the meter stick.
Why when you make measurements should the answer only have the same number of significant figures as the measurement with the fewest significant figures?
This is because the uncertainty in your answer is determined by the least precise measurement. It's no use expecting your answer to be known to 4 decimal places if you are only measuring to the nearest whole mile.
What determines the accuracy and precision of data?
These two qualities are quite different. First off, the concept of 'true value' should be accepted. This is the value to which a large number of measurements tend. Preferably measurements made by different experimenters and by different methods. 'Accuracy' is the closeness to which an individual measurement approaches the 'true value'. 'Precision' is closely related to resolution. And one may have a very precise answer, but still be well away from the true value. Resolution is the number of digits in the answer - and may well have an illusory value.
How do scientists decide which unit of measure they should use?
There are national and international standards for measurements. In America it is the ANSI system, in Europe it is SI.
An experiment was set up to measure the distance a snail would travel in 5 minutes Which of these rulers should be used to give the most precise measurement?
the ansewr is h
Why should your calculations never be more precise than your measurements?
Your calculations can be more precise, but the final result should be rounded, to avoid giving the impression that it is more exact than is justified by the measurements.
What should all scientific experiments have in common?
They all have to exact measurements for everything to make it fair
Why should a burette be read at eyelevel?
Reading a burette at eye level helps minimize parallax error, which occurs when the liquid level appears higher or lower than it actually is due to the angle of viewing. This ensures more accurate and precise measurements when conducting experiments.
Researchers performing a well designed experiment should base their conclusions on?
The conclusion is based on the data that you got from the experiment (experimental results). To write a conclusion you should tell if your hypothesis was correct or incorrect then support your answer from your data. You should always use Quantitative details from the data.
Why is it better to align the meterstick with edge of the object at the 1 cm mark rather than at the end of the stick?
meter sticks give precise measurements and in order to get the full precise answer you should start where the numbers start at on the meter stick.
What is the miniscus?
mEniscus is the curve or crescent of the surface on a liquid or substance and can be concave or convex. The meniscus should be taking in to account when a readings made to make precise measurements.
What are the steps when doing experimental research?
Form a hypothesisDetermine what variables can be varied that should or should not influence results when varied if the hypothesis is correct and if it is incorrectdesign experiments where those variables can be controlled for, and the results measureddetermine the a statistically valid method for running the experiments while controlling for different variablesrun the experiments, recording the resulting measurements and observationsanalyze the results and compare to the results predicted by the theory.
What should the conclusions include?
Conclusions should summarize the key findings of the research, emphasize the significance of the results, and suggest potential implications for further study or real-world applications. Avoid introducing new information in the conclusion and make sure to tie back to the main objectives of the study.
Why should experiments be conducted?
We learn a lot by doing experiments.
Is it true scientists should not repeat experiments to see if thir data is reproducible?
no. experiments should be repeatd
What should be used to make a precise measurment of liquid volume?
A graduated cylinder or a volumetric flask should be used to make a precise measurement of liquid volume. These tools have calibrated markings on the side that allow for accurate measurements to be made. It is important to ensure that the liquid level is read at eye level to minimize any parallax error.
Which should good conclusions do?
