# CH 121L Copiah Lincoln Taking Measurements Comparing with Established Value Lab Report

For the lab report, use the template I added.For the data and calculation for this lab report assume that a dart was thrown at bullseye 3 times with the aim of hitting the middle, the 3 distance from the middle obtain where 3cm, 1cm, and 5cm. Calculate the average, the percent error and discuss in your lab report and emphasize on the accuracy vs precision part

Abstract:
The purpose of this template is to give you all some sort of direction of how this report is
supposed to be written. Today’s procedure called for everyone to read each step and
complete that specific task. The results you should have received were results that allowed
you to get a better grasp of what this experiment was trying to convey. With this data, you
will be able to perform the necessary calculations to complete the datasheet/ report sheet
and draw your final conclusions about the experiment. In conclusion, this is the sentence
in which you will report your final results achieved. Now remember you are able to extent
this paragraph as long as you need to.

Theory:
In this section, you will discuss the background topic that we went over in class today
which dealt with accuracy and precision. For example, accuracy refers to the closeness of a
measured value to the standard or known value. While precision actually deals with the
closeness of two or more measurements to each other. It is usually relative to repetition.
We also mention density and percent error in today’s lab. The formulas for density and
percent error would be nice to see here. More information on these terms would follow
these few sentences, like who came up with these concepts. Lastly, this section should
explain any new ideas associated with your topic. Now remember you are able to extent
this paragraph as long as you need to.

**This caveat is optional, know that you do not necessary need to have the above
statements**
Conclusion:
In conclusion, you mention your final numerical results have with this experiment,
meaning you were able to determine values for average volume, percent error, average
distances of your shots, etc. You were able to gain a better understanding of the topics
discussed, i.e. density, accuracy, precision, percent error. You were able to follow a certain
procedure to achieve your final results. You are able to mention here any difficulties you
encountered. You are also able to mention what you feel would be a better way of
conducting this experiment. Now remember you are able to extent this paragraph as long
as you need to.
