Based on the table, what is the median Operating Cost per Passenger ($) for the express bus routes operating in the Urban Core zone?

The median Operating Cost per Passenger for the Urban Core routes is $3.55.

Filtering the table for 'Urban Core' yields 6 routes. Sorting their Operating Cost per Passenger in ascending order gives:

2.50,

2.90,

3.40,

3.70,

4.10, and

4.80. Because there is an even number of items (6), the median is the arithmetic average of the middle two values (

3.40 and

3.70), which equals $3.55.

Filter the table data for routes located in the 'Urban Core' Zone Type.

Identified 6 Urban Core routes: Route U1 (

3.40), Route U2 (

2.90), Route U3 (

4.10), Route U4 (

3.70), Route U5 (

2.50), and Route U6 (

4.80).

The question specifies finding descriptive statistics exclusively for the Urban Core zone routes.

Order the Operating Cost per Passenger values of the filtered Urban Core routes from least to greatest.

Sorted list of costs:

2.50,

2.90,

3.40,

3.70,

4.10,

4.80.

Finding a median requires ascending or descending order of values.

Calculate the median for the even dataset size (

N = 6

The two central values are the 3rd (

3.40) and 4th (

3.70) elements. Median =

\frac{\$3.40 + \$3.70}{2} = \$3.55

When a dataset contains an even number of elements, the median is the arithmetic mean of the two middle elements.
