Flight tickets

Step-by-step explanation:

Without the cost of flight tickets added to the mix, the average ticket cost is £7.55, and the range of ticket costs is £3.3.

The cost of flight tickets is more than 50 times the previous range above the highest ticket cost otherwise. Hence it can be considered an outlier in the data set.
