An hypothetical data for the number of pets 20 sixth graders have has been given and the box plot that displays the data set is in the image below.
<h3>What is a Statistical Question?</h3>A statistical question can be defined as a question that can be answered by collecting a variety of numerical answers that vary. Examples of statistical questions include:
- What are the age of students in my class?
- What are the heights of students in a class?
A statistical question you can ask at least 20 different people can be: "How many pets do you have?"
Below is the hypothetical questions that can be assumed you'd get from two people:
0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 4, 5, 5
Description of the people you asked can be: 20 sixth graders in your school.
How you gathered your data can be: Asking them to fill a questionnaire or by interview.
The numerical data from least to the greatest, hypothetically would be:
0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 4, 5, 5
The five-number summary for the hypothetical data would be:
Minimum: 0 (least data point)
Quartile Q1: 1 (middle of the first half of the data distribution)
Median: 1.5 (center of the data)
Quartile Q3: 2.75 (middle of the second half of the data distribution)
Maximum: 5 (greatest data value).
Using the five-number summary generated, the box plot that displays the data set is shown in the image attached below.
