Transcript Recognize statistical questions.

Learning Objective
We will recognize1 statistical questions.
CFU
What are we going to do?
What does recognize mean?
Recognize means __________.
Activate Prior Knowledge
Determine the difference between the two question types.
Type A
Type B
“How many hours a week
does Jose spend on math
homework?”
“How many hours a week do
my classmates spend on
math homework?”
“What is the distance from
my house to school?”
“How far do my classmates
travel from home to school?”
“How much does my
backpack weigh?”
“How much does each
student’s backpack weigh
at my school?”
Make Connection
Students, some questions only
have one answer and others
have multiple answers.
Questions that have multiple
answers are good for exploring
real-life problems. Now, we will
recognize statistical questions.

CCSS 6th Grade Statistics and Probability 1.0
Recognize a statistical question as one that anticipates variability
in the data related to the question and accounts for it in the
answers. For example, “How old am I?” is not a statistical question,
but “How old are the students in my school?” is a statistical
question because one anticipates variability in students’ ages.
Lesson to be used by EDI-trained teachers only.
Concept Development
A statistical question expects variability2 in the data3 collected.
• A statistical question is a question that can be investigated4 by collecting a set of data.
Statistical Question
Javier spent 6 hours on math homework last week.
He wants to investigate how much time the students
in his classroom spend doing math homework.
Data Set
“How many hours a week do my
classmates spend on math homework?”
The statistical question can be answered by collecting data on
how many hours students spend on math homework in a week.
Variability in the data collected can be expected because
some students may finish homework faster than others.

on the number of computers her
classmates have at home.
2. Karl is interested in studying the
exercise habits of people in his city.
Statistical Question:
“How many computers do my
classmates have at home?”
