Story: Statistics
Statistics A branch of mathematics.Deals with collecting, analyzing, and interpreting data.
Statistical Questions
A Statistical Question anticipates a Variety of Answers.
What is the height of each student in the classroom?
For instance:
The question implies:
A variability of data (depending on height of each student)
But also:
Collecting some data
Let's see what is and what is not an statistical question.
Let's see some examples:
Example 2:
What is my height?
Example 1:
How much time did each student spend on their last homework?
It is a statistical question.
It is NOT a statistical question
Moving on to the next topic, let's explore some concepts related to statistical questions.
Data Concepts
Every statistical study involves the following concepts:
data set
variable
population
The WHOLE OBJECTS that can be studied in statistical question
Collection of data obtained with SURVEYS, EXPERIMENTS, OBSERVATIONS
A CHARACTERISTIC of interest in objects.
sample
A SUBSET/PART OF THE POPULATION
Statistical question
Let's see some examples:
In a classroom of 30 students, the Physical Education department conducted a survey in order to know the most popular sport among students. So they asked: "What is your favourite sport?"
The results are as follows:
Identify statistical question, variables, population, data set.
Solution
Practice
1/5
Tell whether the following is a statistical question or not:

2/5
Tell whether the following is a statistical question or not:
How many pets do students in our class have?
3/5
Tell whether the following is a statistical question or not:
What's the average height of 6th grade students in my school?
4/5

MATERIAL
It is highly advised to have:
- Grid paper.
- Pencils of different colors.
- Eraser.
- A rule.
- Geogebra installed on your phone/tablet/computer (or use online version).
Standard 1: Develop an understanding of statistics and determine measures of center and measures of variability. Summarize statistical distributions graphically and numerically. MA.6.DP.1.1 Recognize and formulate a statistical question that would generate numerical data. Standard 3: Apply properties of operations to rewrite numbers in equivalent forms. MA.6.NSO.3.5 Rewrite positive rational numbers in different but equivalent forms including fractions, terminating decimals and percentages. Standard 2: Add, subtract, multiply and divide positive rational numbers. MA.6.NSO.2.1 Multiply and divide positive multi-digit numbers with decimals to the thousandths, including using a standard algorithm with procedural fluency.
