Dot Plots, Histograms, and Box Plots
Aligned to 6.SP.B.4 — Common Core State Standards for Mathematics.
What this lesson teaches
Each plot shows numerical data on a number line differently: a dot plot marks each value, a histogram groups values into equal bars, and a box plot shows the median and quartiles. Pick the one that fits your data.
Worked example
For pet counts 1, 1, 2, 2, 2, 3, a dot plot puts two dots above 1, three dots above 2, and one dot above 3 — you can see 2 is the most common.
Practice questions
- Make a dot plot for the data 3, 3, 4, 5, 5, 5.
- You have ages grouped as 10–14, 15–19, 20–24. Which plot fits best?
- Explain what the middle box in a box plot represents.

Diagramas de Puntos, Histogramas y de Caja
Cada diagrama muestra datos numéricos en una recta de forma distinta: el diagrama de puntos marca cada valor, el histograma agrupa valores en barras iguales, y el diagrama de caja muestra la mediana y los cuartiles. Elige el que se ajuste a tus datos.
Ejemplo: Para el número de mascotas 1, 1, 2, 2, 2, 3, un diagrama de puntos pone dos puntos sobre el 1, tres sobre el 2 y uno sobre el 3: se ve que 2 es lo más común.
