The mean is the average. To find that you add them all up and divide the number you get by the number of numbers in the set. So in this case,
3+4+8=15
$\frac{15}{3}=5$
So the mean is 5.
The median is the middle number in a set. So you have to arrange them into numerical order.
3, 8, 4 becomes 3, 4, 8. The middle number is 4, so the median is 4.
Summary:
Mean- 5
Median -4

Explanation:
given observations are 3,8,4
MEAN:
$\stackrel{―}{x}=\frac{3+8+4}{3}=\frac{15}{3}=5$
$\therefore$ mean = 5
MEDIAN:
first we have to arrange the terms in ascending order
3,4, 8
if there are n terms then median is
${\left(\frac{n}{2}\right)}^{th}$ term if n=even, ${\left[\frac{n+1}{2}\right]}^{th}$ term if n=odd
here $n=3⇒$ odd
$\therefore$ median = 4
