Given the information in the document Heart Rate Data, I was able to analyze the data and determine the variables and identify the types.
The three variable groups for this poll or survey are:
The Gender of the subject
- The gender of the subject (male or female)
- Resting Heart Rate
- Heart Rate after exercise
The variable gender is a type of qualitative data because it cannot be measured by numbers. Instead it is a concept that is taken from the subject itself not a number. The numbers on the excel document only distinguish if the subject was male or female not a number being recorded information. The males are represented by 0 and the females are represented by 1. There are 108 males and 92 females. Both these variables put together represent the total amount of people participating in the gathering of information. In total there are 200 people in this poll. This variable was used to identify a class of people, one being male and the other female.
Resting Heart Rate. This variable is a quantitative type of data because it was a measured number that the subjects were tested for. It was taken directly as a measurement and not described as something from the subjects. Unlike the previous variable there is a range for this dataset. There are not one or the other answers as the subjects varied in results. The average resting heart rate for both males and females is 81.0. The numbers ranged from 59.0 to 97.3.
Heart Rate after exercise. Like the heart rate before exercise this again is a quantitative data. The average for both male and females is 90.7. This again is a range of numbers that varies from person to person and was collected data in a measurement form. Both of the heart rate variables provide a specific number that helps represents each individuals heart rate and is used in this dataset. It most likely was the goal to try to determine these numbers. The range for this dataset was 68.2 to 106.7
In the end this data was majority qualitative and can be identified by three different variables with two being qualitative data, before and after exercise heart rate for both males and females.
