Question 1
1.1 Population and Sample
In the study of flight delays, the population would include every flight operated at the
commercial airport during the period being investigated, because the manager would
ideally want information about the complete set of flights. A sample would include
only a smaller group of flights selected from that full population, and the results from
those selected flights would then be used to make reasonable conclusions about
delay patterns at the airport.

1.2 Reasons for Studying a Sample
An airport operations manager may prefer a sample because studying every flight
operated during an entire year would require much more time, staff effort and money
than examining a smaller group of properly selected flights. A sample can also
provide useful information more quickly, which allows the manager to identify
operational problems and make decisions without waiting until data from every single
flight have been collected and checked.
1.3 Classification of Aviation Operations Variables
1.3.1 Type of Aircraft
The type of aircraft used for a scheduled flight is a categorical variable because
categories such as narrow body and wide body describe different aircraft groups
rather than numerical quantities that can be added or averaged.
1.3.2 Number of Flights Experiencing Departure Delays
The number of flights that experience departure delays during a twenty four hour
period is a numerical variable because it is recorded as a count and meaningful
arithmetic calculations can be performed with the values.
