Question

In this assignment, you will be required to use the Heart Rate Dataset to complete the following:

Identify the variables in the dataset

Classify each variable as qualitative or quantitative discrete or quantitative continuous

Specify the possible values of each variable

Give a brief written description of what each variable tells us about the data provided.

Steps

Open the Heart Rate Dataset in Excel

There are 3 columns of data. Each column represents a different variable. What are the 3 variables represented in the dataset?

Identify each of the 3 variables as qualitative, quantitative discrete, or quantitative continuous

Identify the possible values of each of the 3 variables in this dataset.

Briefly describe what information each of the 3 variables tells us about the data

Answer 1

there are 3 variables ,

first column is sex and its value is 0 and 1.This is nominal variable (qualitative variable), and nominal variables are variables that have two or more categories, but which do not have an intrinsic order.

second and third column is heart rate before and after exercise and these are continuous variable (quantitative)  and Continuous variables are numeric variables that have an infinite number of values between any two values.
