Mean
Add all numbers then divide by total numbers.
Total students = 6
[tex]\operatorname{mean}=\frac{5+8+13+5+3+3}{6}=\frac{37}{6}=6.166[/tex]Round to the nearest tenth = 6.2
Answer: mean = 6.2
Median
List your numbers from smallest to largest and chose the number in the middle.
This is: 3, 3, 5, 5, 8, 13
The middle are 5 and 5, therefore:
[tex]\frac{5+5}{2}=\frac{10}{2}=5[/tex]Answer: median = 5
