Describe the range of data and how it helps you understand the data set.
How many pets does each student have?
0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 2, 3, 3, 3, 3, 4, 4
The range is 4-0=4
I am not sure of how can range help you understand the data set?
Students have between zero and four pets each.
Hello Ms. Sue. Okay. That does make sense I did not think about it that way.
Thank you for your help
You're welcome.
The range of data represents the difference between the highest and lowest values in a data set. In this case, the range is 4 (4-0), as you correctly calculated.
The range can help you understand the data set by providing insights into the spread or variability of the data. In this example, knowing that the range is 4 means that the number of pets owned by students varies from 0 to 4. This information gives you an idea of the distribution of pet ownership within the group of students.
If the range were smaller, such as 1 or 2, it would suggest that there is less variability in the number of pets owned. On the other hand, a larger range might indicate a wider range of pet ownership.
By considering the range, you can gather some preliminary understanding of how the data is distributed and assess the diversity or uniformity within the data set. However, it's important to keep in mind that the range alone may not provide a complete picture of the data, so exploring other descriptive statistics or data visualization methods can help further analyze and understand the data.
