Explanation:
The given data is :
195, 194, 191, 190, 238, and 192
Mean = (sum of observations)/(total no. of observations)
![\text{Mean}=(195+194+191+190+238+192)/(6)\\\\=200](https://img.qammunity.org/2022/formulas/mathematics/high-school/tgiwc0zyrns093shobtu6dh4ywtnbi39qj.png)
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
![\text{Median}=((n)/(2)^(th)+((n)/(2)+1)^(th))/(2)\\\\\text{Median}=((6)/(2)^(th)+((6)/(2)+1)^(th))/(2)\\\\=(3^(th)+4^(th))/(2)\\\\=(192+194)/(2)\\\\=193](https://img.qammunity.org/2022/formulas/mathematics/high-school/azp874s6nndu212gwrwyne5gqbgo63lfx3.png)
Hence, this is the required solution
