Step-by-step explanation:
The given data is :
195, 194, 191, 190, 238, and 192
Mean = (sum of observations)/(total no. of observations)
[tex]\text{Mean}=\dfrac{195+194+191+190+238+192}{6}\\\\=200[/tex]
So, the mean is the best measure. Also, w can find median as follows.
arranging in order : 190,191,192, 194, 195,238
Here, n = 6
[tex]\text{Median}=\dfrac{\dfrac{n}{2}^{th}+(\dfrac{n}{2}+1)^{th}}{2}\\\\\text{Median}=\dfrac{\dfrac{6}{2}^{th}+(\dfrac{6}{2}+1)^{th}}{2}\\\\=\dfrac{3^{th}+4^{th}}{2}\\\\=\dfrac{192+194}{2}\\\\=193[/tex]
Hence, this is the required solution
