$\begin{array}{|l|l|l|l|l|l|l|l|l|l|l|l|}\text { Years } & \text { Jan } & \text { Feb } & \text { Mar } & \text { Apr } & \text { May } &\text {jun }&\text {july }&\text {aug }&\text {sep }&\text { oct}&\text {nov }&\text { dec}&\\\hline \text { Year 1}& 4.22 & 5.32 & 5.21 & 5.12 & 4.92 & 4.49 & 4.55 & 4.49 & 4.44 & 4.39 & 4.37&4 .35 \\\text { Year 2}&4.31 & 5.44 & 5.34 & 5.24 & 4.98 & 4.59 & 4.68 & 4.65 & 4.61 & 4.68 & 4.74&4 .79 \\\text { Year 3}&4.38 & 5.51 & 5.41 & 5.36 & 4.98 & 4.63 & 4.71 & 4.78 & 4.82 & 4.88 & 4.85&4 .89 \\\text { Year 4}&4.45 & 5.59 & 5.5 & 5.41 & 5.01 & 4.72 & 4.78 & 4.79 & 4.82 & 4.92 & 5.06 & 5.11 \\\text { Year 5}&4.51 & 5.65 & 5.62 & 5.49 & 5.12 & 4.8 & 4.88 & 4.82 & 4.95 & 5.12 & 5.22&5 .44 \\\hline\end{array}$
a. Use Excel to create sparklines for the average monthly vehicle distance travelled each year.
b. Which year has decreasing trend of the average distance travelled? Which year has increasing
trend of the average distance travelled?
c. Use Excel to create a heat map for the average distance travelled by vehicles. Do you find the
heat map or the sparklines to be better at communicating the trend of the average vehicle distance
travelled over different years? Why?
