Question
In this assignment, you will be required to use the Heart Rate Dataset to complete the following:
Identify the types of data represented by variables
The range or types of values for each variable
Give a brief written description of the variables, and how they are used in the data set.
Steps:
Open the Heart Rate Dataset in Excel
Identify each of the variables contained in the dataset by type
Identify the type of data each variable represents (e.g., qualitative or quantitative) and the possible values for each
Briefly describe how the variable is used in the dataset, (e.g., to identify a class, or to give a specific numeric value for an individual).

1) DataBase contain three variables
X1: Gender,
X2: Heart rates before exersize,
X3: Heart Rates after exersize
2) The first variable is Gender and is Nominal variable(Qualitative) can take only two values as
M=0 and F=1
Another two variables are quantitative variables measured as counts of heart beats in one minues
3) The summery of each variable is
and there are 108 males and 92 females
