Reason and Interpretation

Ticket ID.

Categorical

It is a categorical variable as Ticket IDs are just labels which are

qualitative in nature, and we cannot

perform any meaningful mathematical

operations on it.

Nominal

It has a nominal scale of measurement

because there is no order/rank involved

Neither Discrete nor Continuous

Because it is a categorical variable

Bar Chart

Ticket_ID is categorical variable whose count can be suitably represented through Bar Chart 

Age

Numerical

It is a numerical variable because it

has numeric properties, and we can

perform arithmetic operations

performed on it.

Ratio

It has a ratio scale of measurement because it has numeric properties and

satisfies the absolute zero property.

Also, we can perform addition,

subtraction, multiplication and division

on the variable. Suppose we can say Age of A is twice age of B.

Discrete

Because age can't be a decimal value

Histogram

A histogram is an

appropriate representation

of the distribution of

large data. 

Ticket Price

Numerical

It is a numerical variable because it

has numeric properties, and we can

perform arithmetic operations

performed on it.

Ratio

It has a ratio scale of measurement because it has numeric properties and

satisfies the absolute zero property.

Also, we can perform addition,

subtraction, multiplication and division

on the variable because ticket price.

Continous

Because it can take any values in the interval [10 to 25]

Histogram

A histogram is an

appropriate representation

of the distribution of

continuous data. Therefore,

we can plot a histogram for

Prices” by making

bins.

Movie Genre

Categorical

It is a categorical variable as Movie Genres are just labels which are

qualitative in nature, and we cannot

perform any meaningful mathematical

operations on it.

Nominal

It has a nominal scale of measurement

because there is no order/rank involved

Neither Discrete nor Continuous . 

Because it is a categorical variable

Bar Chart or Pie Chart

As Movie Genre is a categorical variable Bar chart can be used to give count of each genre. 2) Pie Chart can give share of each genre

Seat_Type

Categorical

It is a categorical variable as Seat_Types are just labels which are

qualitative in nature, and we cannot

perform any meaningful mathematical

operations on it.

Ordinal

It has an ordinal scale of measurement as "seat type" consists of levels which can be ordered as Standard<Premium<VIP 

Neither Discrete nor Continuous . 

Because it is a categorical variable

Bar Chart or Pie Chart or Pareto Chart

Seat Type is a categorical variable with

ordinal scale of

measurement. We can plot

the bar chart to represent

the count of the categories by

preserving the order of the

data.

Number_of_Person 

Numerical

It is a numerical variable because it

has numeric properties, and we can

perform arithmetic operations

performed on it.

Ratio

It has a ratio scale of measurement because it has numeric properties and

satisfies the absolute zero property.

Also, we can perform addition,

subtraction, multiplication and division

on the variable. 

Discrete

Because age can't be a decimal value

Histogram

A histogram is an

appropriate representation

of the distribution of large data.

Purchase_Again.

Categorical

It is a categorical variable as Yes or No are just choices in form of labels which are

qualitative in nature, and we cannot

perform any meaningful mathematical

operations on it.

Nominal

It has a nominal scale of measurement

because there is no order/rank involved

Neither Discrete nor Continuous . 

Because it is a categorical variable

Bar Chart or Pie Chart

(i) We can plot a bar chart to

find the count of “No”

and “Yes” in the Purchase Again

category as the bar chart is

a good representative when

we are interested in finding

the “count” of the categories.

(ii) We can plot a pie chart if

we are interested in

comparing the share of

“No”  and

“Yes” preferences.
