1. Understand the Question

compare

After ordering the scores on the number line, how do you find the median, and how is it different from the mean you calculated?

Your job: Answer the question. Use math evidence. Explain how the evidence proves your answer.Responde la pregunta. Usa evidencia matemática. Explica cómo la evidencia demuestra tu respuesta.

2. Plan Your Math Words

Check at least two words you will use.

Mean — The average. Add all the numbers, then divide by how many there are.Media — El promedio. Suma todos los números y divide entre cuántos hay. Median — The middle number when you put them in order.Mediana — El número del medio cuando los pones en orden. Mode — The number that shows up most often.Moda — El número que aparece más veces. Outlier — A number that is much bigger or smaller than the rest.Valor atípico — Un número mucho mayor o menor que los demás. Data distribution — How the data looks: where it sits and how spread out it is.Distribución de datos — Cómo se ven los datos: dónde están y qué tan separados están.

Say it first: Say your idea to a partner or quietly to yourself before you write.Di tu idea a un compañero o en voz baja antes de escribir.

To find the median, I first ___ the scores, then pick the ___.Para hallar la mediana, primero ___ los puntajes y luego elijo el ___.

3. Build Your Explanation

Model the parts: This model shows the parts of an explanation. It does not answer your writing question.

Claim: Mean, median, and mode each describe the center of the data in a different way.

Evidence: Students distinguish the three measures and justify a choice, noting the mode (38) is the most repeated and the mean/median sit near the center.

Reasoning: This evidence connects the definition of mean to the mathematical claim.
