If you think the question has more than one answer write MANY

a statistical question involves a population of individuals or group of objects

6th graders, dogs, pizza

a statistical question focuses on a specific detail of that population or group

height, weight, price

You expect the question would have multiple answers (variability)

How many inches tall are sixth grade students at Sennett?

Elsa 60 inches

Jane 62 inches

Annie 59 inches

Alex 66 inches

cats

Which specific detail of that population or group would you like to focus on?

number of offspring

You expect the question would have multiple answers (variability)

yes, because I have heard of

cats having different amounts of

WHat is Statistics?

CRITERIA FOR A STATISTICAL QUESTION

Turn and Talk:•Why would we ask a question about a population of individuals or objects that (most likely) has more than one answer?

Turn and Talk: Work with A partner

to determine the following

Turn and Talk: What does "distinguish" mean?

To distinguish between a statistical question and a non-statistical question you would ask: Does the question meet the criteria we discussed?

To distinguish between a statistical question and a non-statistical question you would ask: Does the question meet the criteria we discussed?
