Additional work to the analysis of Airmiles pie chart

From what it’s evident on the page 64, top diagram about the products that my respondents spend their airmiles on, there were 43% of the respondents, who said that they don’t use airmiles.

This could have been due to the fact, that they might not be flying enough in order to get the sufficient. However, I have worked out the mean frequency distribution for the length of flights and how often/frequently they fly, provided below. The data provided below suggests, that they have been travelling enough, in order to obtain airmiles, but the fact that they don’t use airmiles can due to several reasons:

• 43% of my respondents simply don’t use airmiles, because they don’t want to, it’s too complicated, or that they don’t want to waste time on this or maybe don’t have enough time to go through the process of registration, in order to be eligible, or do not have enough time to collect enough tickets in order to apply for airmiles, because they don’t save their boarding passes or tickets.
• Alternatively, this could also be caused due to poor information and the fact that some of my respondents didn’t know that airmiles system exists.
• The airmiles system or its interface might be too complicated for some people to understand and be less convenient to use, which might also discourage these people to use airmiles.

Mean Frequency Distribution for the type/length of my respondents' flights
	№ of hours	Mid-point	Frequency	Frequency*mid-point
a) Long-haul flights	8 to 24
b) Medium-haul flights	3 to 7
c) Short-haul flights	0 to 1	0.5		0.5
Total:		21.5		164.5
(frequency*mid-point)/frequency= 164.5/25= 6.58
6.58 hours- is an estimted length of the flight that most of my respondents use

Mean Frequency Distribution for how often my respondents fly
	№ of times	Mid-point	Frequency	Frequency*mid-point
a) 1-2 times a year	1 to 2	1.5
b) 3-5 times a year	3 to 5
c) Other	5 to 12	8.5		93.5
Total:				129.5
(frequency*mid-point)/frequency= 129.5/25= 5.18
approx.= 5 times a year is an estimated number of times when my respondents fly per year

Mean Frequency Distribution for the 'other' types of flights that my respondents choose
out of 44% of those who chose 'other'
	№ of times	Mid-point	Frequency	Frequency*mid-point
a) 6-8 times	6 to 8
c) 10-12 times	10 to 12
f) 16- 20 times	16 to 20
Total:
(frequency*mid-point)/frequency= 97/10= 9.7
approx.= 9.7 times a year is an estimated number of times when the respondents who
chose 'other' flyper year
