1. First Section: Introduction and Background:
1. a)
The transportation is the New South Wales is the leading agency of the New South Wales
transportation cluster. The role is transportation is to establish a more efficient, safer and integrated
transportation system (Amiril et al. 2014). The transportation system majorly keeps people moving
and links the communities of the centers, suburbs, regions and cities. The well-known types of
transportation system of New South Wales are ‘rail’, ‘bus’, ‘light rail’ and ‘ferry’. Public and people
who are equally associated to the transportation system, are equally responsible for planning, policy,
regulation, strategy, allocation of funding and non-service delivery functions.
The transportation system focuses to enhance the ‘customer experience’ and links the
‘public and private operators’ for delivering customer-oriented transport services on their behalf
(Ghaderi et al. 2015). The procurement of transport infrastructure and delivery through ‘project
delivery industry’ are maintained by co-ordination of all people in the New South Wales.
1. b)
The first data set that is provided by my organization is secondary data. The data is collected
by other person and now I am using the data in this statistical documentation. Therefore, the data
set is secondary to me. Although, the data set could be biased and erroneous, I am performing the
analysis with that secondary data with true belief.
The variables that are involved in the data set is qualitative as well as quantitative. The first
variable ‘Mode’ is the indicator of mode of transportation that is nominal (categorical) variable. It
has four levels that are ‘Bus’, ‘Train’, ‘Ferry’ and ‘Light Rail’ (Clark 2013). The second variable ‘Date’
refers the date given in Date/month/year notation. It is another nominal (categorical) data. The
dates are from 8th August, 2016 to 14th August, 2014. ‘Tap’ variable has two levels that are ‘On’ and
‘Off’. It is another nominal (categorical) data. ‘loc’ variable denotes the location of stops in New
South Wales (for bus postcodes and other names of the stations). ‘count’ variable denotes the total
number of tap on and tap off on the certain location and certain date. It is the quantitative variable.
1. c)
I have collected the data set by survey method. The target population was the common
population of New South Wales who travel by transportation services. The data of only gender and
transportation data is collected in this regard. The data set is primary data as I myself have collected
the data set. The variables of the new collected data set are qualitative in nature. However, the
number of samples of the data set is not adequately large. Also, the primary data set has only two
variables; hence, it is in-sufficient and inadequate.
