Recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number.
Informally assess the degree of visual overlap of two numerical data distributions with similar variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability. For example, the mean height of players on the basketball team is 10 cm greater than the mean height of players on the soccer team, about twice the variability (mean absolute deviation) on either team; on a dot plot, the separation between the two distributions of heights is noticeable.

En cada caso, decide cuál de los dos conjuntos de datos escogerías. Usa la mediana y el rango intercuartil para apoyar tu elección.
Una familia está decidiendo a cuál restaurante ir. Estas son las calificaciones de las inspecciones sanitarias de cada restaurante durante el último año. Teniendo en cuenta las calificaciones de los restaurantes, ¿a cuál restaurante debería ir la familia?
Al final del año pasado, los profesores fueron calificados por sus estudiantes en una escala de 0 a 10. Estas son las calificaciones que recibieron dos profesores. ¿En cuál clase te inscribirías? Explica tu razonamiento.
Profesor A: 9, 8, 10, 10, 7, 1, 8, 1, 2, 8

Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2.
Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.
