The 'control group' is an essential component of an experiment. This is because
1. A control group allows one to determine if a particular result is due to the experimental variable.
2. No, it's not essential in experimentation. A control group is not always necessary it depends on the experiment.
3. A control group allows for multiple variables to be tested at the same time.
4. A control group is required for the development of a prediction.
Which of the following is not correctly linked?a. model: a representation of an object used in an experimentb. standard deviation: a form of statistical analysisc. principle: a theory that is not supported by experimental evidenced. data: the results of an experiment or observation
What are three important thing you will consider when settting up an experiment to investigate a phenomenon? Explain why?

You describe theresults you obtained and then discuss what you learned. There are several ways to write a lab report,and depending on your class or your instructor, the requirements will vary. But this guide is to helpyou understand the reason why writing a lab report is an important part of the science process. It willalso introduce the basic structure of one type of write-up.In college, any science course you take will require you to do a lab report. But they are not just busywork. They actually serve a purpose. You see, a written report is one of the main ways to share information to other scientists. It communicates the major points of an investigation to others who are ina similar field. This is a systematic way to spread information!Lab reports have their own unique style and format, too. Though you may have been taught to writepoetically and with artistry, lab reports require…arrow_forward
