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.
According to the scientific method, any scientific experiment must be done at least 3 times. Also, only one variable can be changed in an experiment (the independent variable). Any more changes will will ruin your dependent variable (your results) and make your data unreliable. If your experiment fails, learn from it, redo the experiment, and change another variable.
Scientists use technology to have another way to look at things.You use technology to look at planets,cells,etc.
you mean method for getting a result (as in finding your pulse?) 2 places are your neck (alot more difficult to find) and your wrist...on your left hand...on the left side of wrist...just below where it joins your hand...a nice strong signal to be found here!
Redo the experiment multiple times. If the results are consistent, the experiment becomes more accurate. minimize errors of the experiment by controlling and characterizing the errors beforehand
To improve your reaction time ,try dropping a ruler and catching it
There are a number of different things which can improve the estimate:select an appropriate estimation method,repeat the experiment more times,Improve the accuracy of your measurement,ensure that other variables are properly controlled.

Guarding against hidden or unexpected variables is important to ensure the reliability and validity of study results. These variables can introduce bias and confound the relationships between variables of interest, leading to inaccurate conclusions. By identifying and controlling for these variables, researchers can improve the quality and credibility of their findings.
Limit variables. Use accurate measuring equipment. Use multiple trials to obtain data that can be averaged. Observe intently.
