Scouting Report
You've just been hired as the data analyst for a youth basketball league. The head coach hands you a list of questions the staff wants to investigate about their players. Some questions will give you interesting data with variety, while others have just one fixed answer. Your job: figure out which questions are worth investigating with data.
Concept Launch
💡 What makes a question a statistical question?
A statistical question is one you answer by collecting data, and the answers are different for different people or cases. A non-statistical question has just one fixed answer.
If you expect the answers to vary, it is a statistical question.

VOCABULARY
⏱ ~8 min
| Term / Término | Meaning / Significado | Example / Ejemplo | Visual |
|---|---|---|---|
| Statistical Question Pregunta estadística |
A question where the answers will be different for different people. Una pregunta cuyas respuestas serán distintas para distintas personas. |
"How tall are the players on the team?" → answers vary: 60 in, 63 in, 58 in, 65 in | |
| Data Datos |
Facts and numbers you collect, like answers to a survey. Datos y números que recoges, como respuestas a una encuesta. |
Player heights: 60 in, 63 in, 58 in, 65 in — four different measurements | |
| Variability Variabilidad |
How spread out the numbers are. Qué tan separados están los números. |
Scores 10, 12, 11 are close together (low variability); scores 2, 15, 30 are far apart (high variability) | |
| Survey Encuesta |
Collecting facts by asking people questions. Recoger datos haciendo preguntas a las personas. |
Asking 50 students 'What is your favorite sport?' and recording the answers | |
| Data distribution Distribución de datos |
How the data looks: where it sits and how spread out it is. Cómo se ven los datos: dónde están y qué tan separados están. |
If most scores cluster in the middle with fewer at the edges, the distribution is symmetric |
Which Word Fits?
A question that expects a variety of answers and is answered by collecting data is a ___.

The coach asks, "How tall is our point guard?" and "How tall is each player on the roster?" Which one is a statistical question, and why?
👂 Listen For
Students identify "How tall is each player?" as statistical because heights vary, while "How tall is our point guard?" has one fixed answer.
Extend: Take a non-statistical question and reword it so it becomes statistical. Explain exactly what you changed to create variability.

While sorting the questions, what clue tells you instantly that a question will need DATA from many players to answer?
👂 Listen For
A strong answer notes words like "each" or "per player" signal variability, so you must collect data from many cases rather than look up one fact.
Extend: Is it possible for a question with a numerical answer to still be NOT statistical? Justify with an example from the basketball league.

Real-World Connection
🌍 Math in the Wild
The school newspaper wants to write a story about the girls' soccer team. A reporter suggests asking: "How many goals has the team scored total?" The editor says they should ask: "How many goals did each player score this season?"
✍️ Connection Reasoning
Which question is statistical? Why would the editor's question give the newspaper more interesting data?
The reporter's question is ___ because ___. The editor's question is ___ because ___. The editor's question is better for a story because ___.
Turn & Talk — Connect
The newspaper editor prefers "How many goals did each player score?" over "How many goals did the team score total?" Which gives more interesting data for a story?
👂 Listen For
Students explain the per-player question is statistical and shows variability (who scored most/least), while the total is one fixed number that hides individual differences.
Extend: Critique the reporter's plan: when might a single total actually be the RIGHT thing to report instead of per-player data? Defend your view.

🎯 Listen For · Common Errors
• Students identify "How tall is each player?" as statistical because heights vary, while "How tall is our point guard?" has one fixed answer.
• A strong answer notes words like "each" or "per player" signal variability, so you must collect data from many cases rather than look up one fact.
• Students explain the per-player question is statistical and shows variability (who scored most/least), while the total is one fixed number that hides individual differences.
• Students pose a question whose answers vary across classmates and name the variability they expect (e.g., different bedtimes, different shoe sizes).
Common mistake: A common mistake in Statistical Questions and Data is skipping the key idea: "If you expect the answers to vary, it is a statistical question." — always check your work against this rule before you submit.
Answer Key (Teacher Appendix)
Hide this slide during presentation or move to the end of your copy.
✓ Practice 1: Because the answers will vary from athlete to athlete — A statistical question anticipates variability. Different athletes sleep different amounts, so the data collected will vary.
✓ Practice 2: How tall are the students in my class? — A statistical question anticipates variability — students' heights differ, so the data will vary.
✓ Practice 3: How many siblings does each student in the class have? — Number of siblings varies from student to student, so the collected data will vary — that makes it statistical. The others each have one fixed answer.
✓ Practice 4: How many points did each player score this season? — "How many points did each player score?" is statistical because different players will have different scores — there is variability in the data.
✓ Exit ticket: B) How many hours does each student exercise per week? — "How many hours does each student exercise per week?" is statistical because different students exercise different amounts — the data has variability.
