Question

Find the mean of the range and the mode of the given data.
$4,6,11,17,18,3,11,21,5,11$.

Answer 1

Given data $4,6,11,17,18,3,11,21,5,11$

No of observations $\left(n\right)=10$

Here highest value $=18$

lower value $=3$

$\therefore$ Range = Highest value - lower value

$=18-3$

$=15$

mode means which is most frequently occurred in above data observe that '11' is most frequently occurred

$\therefore$ mode $=11$

$mean=\frac{sumofobservations}{no11ofobservation}$

$=\frac{4+6+11+17+18+3+11+21+5+11}{10}$

$mean=\frac{107}{10}=10.7$
