Statistical Questions Flashcards

Study Notes

Statistical Questions

A statistical question anticipates varied responses, such as "How tall are your classmates?"
Non-statistical questions yield a single answer, like "How tall is Jane?"
Yes/no questions do not qualify as statistical questions.

Non-statistical Questions

Defined as questions that can be answered definitively with one response.
Examples include "What is your favorite color?" and "How many books did you read today?"

Identifying Statistical Questions

Assess whether a question has the potential for diverse answers or if it can be definitively answered.

Examples of Statistical vs. Non-statistical Questions

"How many days are in April?" is non-statistical; it has a singular answer.
"How old is my dog?" is also non-statistical with only one answer.
"How old are the dogs that live on your street?" qualifies as statistical as it requires data collection and offers various answers.
"How many pets do students at your school have?" is statistical due to the expected variability in responses.
"What is the favorite food of students at Berea Middle?" is statistical for similar reasons.
"Do you like watermelon?" is non-statistical, providing just one answer.
"What was the temperature at noon today at City Hall?" is non-statistical, with a single definitive response.

Data Collection

Data collection involves gathering information through methods like surveys, interviews, or research.
