What things must you do after your experiment is complete be specific?
After conducting experiments, the laboratory, especially the work areas, must be kept clean and organized . Make sure that all the electrical equipment must be unplugged and returned to its proper place or cabinets. More importantly, proper waste disposal must be followed.
Why do you need to prepare all the materials needed before the experimentation?
You need to familiarize yourself with the entire experiment, including the equipment you will be using (shown in the experiment section and/or in this section). Two major purposes of the lab notebook are: (1) to guarantee the integrity of the data ; and, (2) to ensure repeatability of an experiment.

Which two things are needed for every experiment?
An experiment is a procedure designed to test a hypothesis as part of the scientific method. The two key variables in any experiment are the independent and dependent variables . The independent variable is controlled or changed to test its effects on the dependent variable.
What makes a good experimental procedure?
A good procedure is so detailed and complete that it lets someone else duplicate your experiment exactly ! Repeating a science experiment is an important step to verify that your results are consistent and not just an accident. For a typical experiment, you should plan to repeat it at least three times (more is better).

- Step 3: Design your experimental treatments. ...
- Step 4: Assign your subjects to treatment groups.
How do you redirect an experiment?
- Create an experiment and set up the targeting.
- Add the redirect to your variation.
- Set up a page to track events across all URLs. Create a click event.
- Select metrics and audiences for your experiment.
- QA and publish your experiment.
- Best practices.
What recommendations can you make to improve the results of your 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 can you improve the reliability of an experiment?
Improve the reliability of single measurements and/or increase the number of repetitions of each measurement and use averaging e.g. line of best fit . Repeat single measurements and look at difference in values. Repeat entire experiment and look at difference in final results.
