Equipment had limited display, student ruler can measure up to a mm and for a string of 10 cm it will have error of at least +/- 1mm. An experiment usually required to measure many thing like mass - volume - length - energy and each of these little error would sum up to the experimental error.
all know is that it would be a fair test
The first must be inaccurate because you are sure the second results are correct.
If some of the water splashes out, then the volume that you measure will be inaccurate, in that it will appear to be less than it actually is. This will cause the calculated density to be inaccurate, in that it will appear to be greater than it actually is.

Pregnancy and hemophilia are two main reasons that these tests are inaccurate.
Experimental variables need to be controlled because they can cause the experiment to be flawed. Variables can change the experiment, and even if it's not a very big change, it will still make the experiment unreliable. For example, let's say a person is trying to see which laundry detergent is better. They stain four shirts with grass stains, and then apply detergent to each one. The experimental variable in that experiment is the stains; In order for the experiment to be accurate, the person doing the experiment must make sure that they put the same amount of grass stains on each shirt. Otherwise, it would be a very incorrect, inaccurate experiment.
In an experiment, your control variable will not be caused to vary by the experiment. Think of 'cause and effect'. The independent variable is the cause, the result is the effect, and the dependent variable is the one that you leave to be changed by the experiment.
One possible source of error in a refraction experiment is misalignment of the light source, causing it to not travel directly through the center of the refracting material. This can result in inaccurate measurements of the angle of refraction.

Cause and Effect.
Yes, it is important to have accurate measurements in an experiment because they can directly impact the validity and reliability of the results. Inaccurate measurements can lead to flawed conclusions and unreliable data. Using precise measuring instruments and techniques helps ensure the quality of the experiment.
Avoiding light in the determination of iodine value is important because iodine is light-sensitive and can react with light, leading to inaccurate results. Light exposure can cause the iodine to degrade or evaporate, which would affect the measurement of the iodine value. By conducting the experiment in a dark environment, you ensure the accuracy and reliability of the iodine value determination.

Some sources of errors for a density experiment include inaccurate measurements of mass and volume, temperature fluctuations affecting the density of the substance, and inconsistencies in the sample preparation process. Other errors may arise from equipment limitations and human error during the experiment.
