It's important to control your experiment so that you can be sure the results are due to the experimental variable (independent variable) and not something else.
Experimental data is an important component of any scientific paper.After looking at the data, we can compare that to our hypothesis and see if it matches to our tentative idea.Analysis of experimental data also helps us to draw a conclusion of an experiment.
Accounting for errors in an experiment will determine the validity and reliability to the experiment. This, in turn, will either support the experimental results by accepting the null hypothesis or to discard the experimental results by rejecting the null hypothesis
Because we need to find the temperature of the surroundings
Science is based around experimentation and then creating a theory to support the evidence found through your experiment. Therefore with out experiments you have no science.
The control experiment allows a standard of comparison for the experimental group

A control group is the standard of comparison between what happens with the experimental variable and without the experimental variable.
if you could only record a single temperature reading in a freezing point determination experiment, which temperature should you record

STP stands for Standard Temperature and Pressure, whereas ETPis Experimental Temperature and Pressure.All laboratory experimental data should should include the ETP. This is especially important when studying reproducibility of results, and in Kinetics and Catalysis studies.
so the solution will not be contaminated or changed during the reaction
When doing experimental research, it is important to limit
While conducting an experiment, it is important to have a experimental control. Suppose you are conducting an experiment to determine what factors affect the rate of evaporation of water. If you want to determine if presence of wind affects evaporation, you can take two containers of water and place one in a windy place and the other in a place with no wind. However all other factors should be identical like surface area of containers, surrounding temperature, liquid quantity and temperature etc. Hence, the need for a controlled experiment is to eliminate bias and to ensure that the data is valid.
