How can you ensure the accuracy of your results which conducting a scientific investigation?
Check if the results are valid
What is accuracy and precision and the difference between them?
The term accuracy describes how far your observation/measurement is from the correct result. Precision describes how repeatable your results are, regardless of their accuracy..
Can accuracy depend on the precision of the instrument?
Of course, if the instrument is flawed so will the results.
Which of the following is an effect of increasing the wavelength of an electromagnetic wave?
Increasing the wavelength results in decreasing the frequency and decreasing the energy.
How zero error affect accuracy?
It will create a consistent shift in all your results; it is a systematic error. Eg, might cause all your results to increase by 5.
How do laboratory tools improve observations made by a scientist?
Primarily by increasing accuracy, and next by increasing efficiency.

When conducting scientific investigations increasing trials also increases what?
accuracy

What is the results of increasing the volume of gas?
Increasing the volume of a gas the pressure and density decreases.
Which is not a preanalytical variable that can affect the accuracy and precision of laboratory test results?
*
What describes how well the results of an experiment agree with the standard value?
Accuracy.
How do you improve accuracy by controlling the variables more carefully?
Accuracy is how close together your results are each time you repeat an experiment, so keeping the variables as constant as you can ensures your results differ as little as possible.
Why did surveyors use plumblines?
Plumblines ensure equipment is vertically 'true' - increasing the accuracy of measurements.
What results from increasing the temperature of a gas?
The gas expands.
What is the meaning of getting the same results on repeated trials?
If you repeat the experiment and you get different results, then the accuracy of your first trial is not correct.
Can accuracy depend on the precision of the instrument?
Of course, if the instrument is flawed so will the results.
