Consider an ecological study of the insect populations in a region. Pit traps are set out overnight, and the number of insects in each trap is recorded the next day.

Number of insects found in pit traps.

$\begin{array}{l}
\text { Number }\
\begin{array}{cc}
\text { of insects } & \text { Frequency } \
\hline 0 & 25 \
1 & 20 \
2 & 20 \
3 & 25 \
4 & 10 \
5 & 5
\end{array}
\end{array}$
Using the data shown in the table, calculate the mean, median, variance, standard deviation, coefficient of variation, and interquartile range for the data values. Also, what proportion of traps failed to trap any insects?
