While doing the science experiment in the physics lab, Mary Kom had to take 4 measurements of the temperature and write the average of those as an answer. If the measurements of the temperature is 2, 0, -2, -4, what is the final answer of her experiment?

Given :
Four measurements of temperatures are 2, 0, -2 and -4.
To find :
Average of the measurements
Solution :
We have four different numbers with us i.e. 2, 0, -2 and -4.
We know that,
[tex]Average = \frac{ (Sum \: of \: Observations)}{ (Total \: Numbers \: of \: Observations)} \\ [/tex]
For calculating the average of the temperature measurements, we will use the above formula..
Hence,
[tex]Average = \frac{2 + 0 + ( - 2) + ( - 4)}{4} \\ [/tex]
[tex] = > \frac{ - 4}{4} \\ [/tex]
[tex] = > - 1[/tex]
Therefore, the final answer of her experiment is -1
Hope it helped you...
Thank you !!!
