The midrange is the sum of the minimum and maximum data value divided by $2$.
The mode of $n$ numbers is the number or numbers that appear(s) most frequently. If all items appear the same number of times, then there is no mode.
The median of $n$ numbers is the middle number of the numbers when they are in order (and the mean of the middle $2$ numbers if $n$ is even).
The mean of $n$ numbers is the sum of the numbers divided by $n$.
Here we have $16$ items (obtained by summing the numbers in the right column), thus the mean will be the mean of the $8$th and $9$th item, which according to the table is: $(13+13)/2=13$.
Here the midrange: $\frac{10+15}{2}=12.5$, the mode: $13$ and the mean: $\frac{1\cdot10+2\cdot11+4\cdot12+5\cdot13+2\cdot14+2\cdot15}{16}\approx12.69$.
