What describes how well the results of an experiment agree with the standard value?

How well the results of an experiment agree with the accepted value. This is the sum of each number in a set added together and then divided by the total number in the set. You just studied 35 terms!

What is the result obtained from an experiment?

“Results” Means the Ending of a Scientific Story The results are simply the end of the scientific experiment: What you found in your study.

What is an appropriate way to analyze the results of an experiment?

Data Analysis & Graphs

1. Review your data. Try to look at the results of your experiment with a critical eye.
2. Calculate an average for the different trials of your experiment, if appropriate.
3. Make sure to clearly label all tables and graphs.
4. Place your independent variable on the x-axis of your graph and the dependent variable on the y-axis.

When you repeat an experiment do you get the exact same results each time why or why not?

Repeating Experiments Three repeats of an experiment is generally considered the minimum. Why? There are two reasons, the first has to do with the fact that three repeats ensures a two-thirds (66%) probability that the averaged results are more accurate than a single experiment.

Why is more trials more accurate?

Repeated trials are where you measure the same thing multiple times to make your data more reliable. This is necessary because in the real world, data tends to vary and nothing is perfect. The more trials you take, the closer your average will get to the true value.

How do you explain accuracy in results?

You can test the accuracy of your results by:

1. comparing measurement to the value expected from theory for single measurements.
2. comparing the final experimental result to the accepted value for entire experiment’s result.

How do you ensure validity in an experiment?

You can increase the validity of an experiment by controlling more variables, improving measurement technique, increasing randomization to reduce sample bias, blinding the experiment, and adding control or placebo groups.

How do you explain reliable?

deserving trust; dependable: My car is old but it’s reliable.

Why is it important to be reliable and dependable?

Knowing that someone will not only show up, but show up on time, helps us trust each other. Following through on our promises is a way that people know that they can trust and depend on us. Being dependable and reliable tells others that their time is important and that we respect them.
