The question about the distance from the school's front door to the flagpole has one fixed, measurable answer that will not vary regardless of who answers it. This makes it non-statistical. The other three questions all anticipate variability: homework hours will differ among students, student heights vary significantly, and lunch spending varies by individual choices and circumstances.

When analyzing survey questions for data collection, you need to distinguish between questions that reveal variable data (information that changes from person to person) versus fixed information (facts that remain constant regardless of who answers).

The correct answer is D because "What is the official start time for first period at our school?" asks for a fixed fact that never changes. Every student would give the exact same answer since there's only one official start time. This provides zero information about student variability or preferences – it's simply asking for a school policy that's already established.

Let's examine why the other options are wrong: Choice A asks about music preferences, which will vary significantly among students – some might prefer pop, others rock, hip-hop, or country. Choice B asks about social media usage time, which will produce a wide range of responses from zero minutes to several hours daily. Choice C asks about desired after-school activities, where students will suggest different sports, clubs, or programs based on their individual interests.

Notice that options A, B, and C all ask "what do you prefer/do/want" while option D asks "what is the official policy." The first type generates diverse responses that help understand the student body, while the second type simply confirms existing information.

Strategy tip: When evaluating survey questions, ask yourself "Could different people reasonably give different answers to this question?" If everyone would give the identical response, it won't provide useful variable data for decision-making.

This question tests the subtle understanding that statistical questions can ask about individuals when the specific individual is unknown or randomly selected, creating uncertainty and anticipated variability in the answer. Even though it asks about "a" student (singular), we don't know which student, so the age could vary. Choice A is clearly statistical (group variability). Choice B is clearly non-statistical (specific person, definite answer). Choice D, while involving statistics, asks for one calculated value rather than anticipating variability in responses.

A statistical question anticipates variability in responses. "How many pets do students in our class have?" expects different answers from different students (some may have 0, 1, 2, or more pets), making it statistical. "How many pets does Sarah have?" has only one specific answer, making it non-statistical. Choice B contains two statistical questions since both anticipate variability. Choice C contains two statistical questions since both height and weight vary among individuals. Choice D contains two non-statistical questions since both have fixed, single answers.

"How many smartphones do people in this city typically own?" is statistical because it anticipates variability - different people will own different numbers of smartphones (0, 1, 2, or more), creating a data set that can be analyzed. The other three questions all have single, factual answers that do not vary: the iPhone release year is 2007, the CEO has one name, and there is one official price for the newest model.

A question is statistical if it is designed to anticipate variability, regardless of whether the actual responses vary. For example, "What is your favorite subject?" is statistical even if all students happened to answer "math." The key is whether variability was expected when the question was written, not whether variability actually occurred in the responses. Choice A incorrectly focuses on the outcome rather than the question's design. Choice B incorrectly assumes multiple respondents make a question statistical. Choice D is irrelevant to determining if a question is statistical.

When you encounter questions about data collection, you need to distinguish between questions that yield a single answer versus those that produce multiple data points that can be analyzed.

Question D asks "What eye colors are represented among students in our class?" This produces a data set because you'd collect individual responses from each student (brown, blue, green, hazel, etc.), creating multiple data points that could be organized, counted, and analyzed in various ways.

Let's examine why the other options produce single values: Option A asks for "the total number of books in our school library" — this yields one specific number, not a collection of data points. Option B seeks "the most common eye color" — while you'd need to collect data to find this answer, the question itself asks for just one result (the mode of the data). Option C asks for "what percentage of our class has brown eyes" — again, this requires data collection but produces a single percentage as the final answer.

The key difference is that option D asks for all the different eye colors present, which means you're looking for the range of values in your data set rather than calculating or identifying one specific result from that data.

Remember this pattern: questions asking "what types," "what kinds," or "what varieties" typically produce data sets, while questions asking for totals, percentages, averages, or "most common" typically produce single calculated values.

This pair demonstrates how wording affects whether a question is statistical. "What was the highest score on yesterday's math test?" asks for one specific value (non-statistical), while "What scores did students earn on yesterday's math test?" anticipates multiple different values showing variability (statistical). Both questions are about the same test, but the wording changes whether variability is expected. The other choices either ask about different topics or contain questions that are both non-statistical.

This question tests recognizing statistical questions as those anticipating variability in data (expect different answers from different subjects), vs non-statistical (single answer, no variability expected). Statistical questions anticipate data will vary (not all same answer), requires collecting multiple data points showing distribution; examples include 'How old are students in my school?' which expects variability (ages differ: some 11, some 12, some 13—data varies across students, statistical) and 'How many pets do students have?' which anticipates varying answers (0,1,2,3,... pets differ by student, statistical), while non-statistical have a single answer with no variability, like 'How old am I?' (one person, one age: 12, no variability—not statistical) or 'What is 5+3?' (one answer: 8, no data collection, not statistical), with variability being key since statistical questions are designed knowing answers will differ, accounting for variation in responses. For example, 'How tall are 6th graders?' is statistical (heights vary: 140 cm, 155 cm, 162 cm, 170 cm for different students, data distribution expected, anticipates variability), while 'How tall is the tallest 6th grader?' is not statistical (asks for one specific value: tallest is a single measurement like 170 cm, no variability—specific answer), and 'What is the average sleep hours?' is not statistical (average is one calculated value, even though based on varied data, the average itself doesn't vary—asking for single number). The rewrite in B is statistical because it expands to multiple students on a typical day, expecting varying practice times, while others remain focused on one instance or a fixed fact, so choice B is correct. A common error is thinking slight changes like adding a time or rounding make it statistical, but they still yield single answers without variability; another mistake is confusing math facts with data collection. To recognize statistical questions: (1) read the question carefully (what is being asked?), (2) consider the subjects (one person? or multiple people/trials?), (3) anticipate the answers (would answers vary? or single answer?), (4) classify (variability expected→statistical, single answer→not statistical). For instance, 'How many books did students read?' is statistical (varies by student: 2,5,8,12 books for different students, distribution expected), while 'How many books did I read?' is not (one person, one answer: 8 books, no variability); the key is variability in data, not just asking about multiple items—'What is the tallest player height?' asks about multiple players but wants one specific answer (tallest), so not statistical, and mistakes include confusing broad scope with variability (broad≠statistical if asking for single value) or thinking group questions are always statistical (specific within group can be single answer) without checking if variability is expected.

When you encounter questions about statistical thinking, focus on whether the question anticipates variability in responses. A statistical question expects different answers from different individuals or observations.

The question "How long does it take students in our school to eat lunch?" is definitely statistical because it asks about individual eating times, which will vary from student to student. Some students might finish their lunch in 10 minutes, others might take 25 minutes, and still others might fall somewhere in between. This variability in eating speeds makes it a statistical question.

The correct answer is B because the student confused two completely different things: the lunch period duration (which is fixed at 30 minutes for everyone) with individual eating time variations (which differ from person to person). Just because the lunch period is always 30 minutes doesn't mean every student uses all 30 minutes to eat.

Answer A is wrong because time-based questions can absolutely be statistical - this question proves it. Answer C is incorrect because not all questions about groups are automatically statistical; for example, "What is the name of our school?" is about a group but expects only one answer. Answer D is completely off-track since statistical questions have nothing to do with having exactly four answer choices.

Study tip: When identifying statistical questions, ask yourself: "Would I expect different answers if I asked this question to multiple people or observed multiple cases?" If yes, it's statistical. Don't get distracted by fixed constraints like schedules or rules.
