Answer 1

Answer:

Step-by-step explanation:

Mean, Median,mode

   $\boxed{Mean = \dfrac{Sum \ of \ all \ data}{number \ of data}}$

              $\sf = \dfrac{234 + 247 + 236+212+248+243+176+195}{8}\\\\= \dfrac{1791}{8}\\\\= 223.875$

Median:

Arrange the numbers in ascending order.

  176 , 195 , 212 , 234 , 236 , 243 , 247, 248  

Number of data is even. So, median will be the average of 234 and 236

Median = average of the middle two terms.

            $\sf = \dfrac{234+236}{2}\\\\ =\dfrac{470}{2}\\\\= 235$

Mode is the data which is occurring more number of times.

Range = maximum - minimum

           = 248 - 176

            = 72
