NAME:  Hat measurements, including hat size
TYPE:  Observational
SIZE:  26 observations, 6 variables

DESCRIPTIVE ABSTRACT:
 
The dataset contains hat size as well as circumference, length of major axis 
and length of minor axis of the inner hat band for 26 hats. The manufacturer 
and the country of manufacture are also included.

SOURCE:

Katherine Brady and Kari Cornelius, Carleton College ('96) students, gathered 
the observations from hats at a store at the Mall of America in Bloomington, 
Minnesota.

VARIABLE DESCRIPTIONS:

Variables 
1         Hat size
2         Circumference (inches)
3         Length of major axis (inches)
4         Length of minor axis (inches)
5         Where made? Italy = 1, U.S.A. = 2
6         Manufacturer? Beaver = 1, Borsalino = 2, Dobbs = 3, Stetson = 4

please answer the follow question

How many variables are there, and how are they defifined?

• Which variables are quantitative and which are categorical?

• What are the units of measurement for each quantitative variable?

• What questions do you plan to investigate in your project? These may be questions that were of interest

to the researchers who collected data, or they may be questions that you thought of yourself. Make sure to

include questions that you can hope to answer using methods from this course.

How many variables are there, and how are they defifined?
There are 6 variables
They are defined as
1         Hat size
2         Circumference (inches)
3         Length of major axis (inches)
4         Length of minor axis (inches)
5         Where made? Italy = 1, U.S.A. = 2
6         Manufacturer? Beaver = 1, Borsalino = 2, Dobbs = 3, Stetson = 4

• Which variables are quantitative and which are categorical?
These 4 are quantitative: -
1         Hat size
2         Circumference (inches)
3         Length of major axis (inches)
4         Length of minor axis (inches)

these are categorical: -
5 Where made? Italy = 1, U.S.A. = 2
6 Manufacturer? Beaver = 1, Borsalino = 2, Dobbs = 3, Stetson = 4

• What are the units of measurement for each quantitative variable?
units for all variable are in inches

• What questions do you plan to investigate in your project?

If there is a linear pattern between hat size versus circumference

There can be many questions you can frame

Create a class called Vehicle that includes four instance variables: name, type, tank size and average petrol consumption. Provide 2 constructors, the first takes name and type as parameter, the second takes four parameters for the four instance variables. (2 pt) Provide also a method called distancePerTank that calculate the average distance that a vehicle can travel if the tank is full (multiplies the tank size by the average petrol consumption), then returns the value. (2 pt) Provide a...
