- HSS-ID.B.5Summarize categorical data for two categories in two-way frequency tables. Interpret relative frequencies in the context of the data (including joint, marginal, and conditional relative frequencies). Recognize possible associations and trends in the data.
- HSS-ID.B.6Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.*

- HSS-ID.B.6aFit a function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear, quadratic, and exponential models.
- HSS-ID.B.6bInformally assess the fit of a function by plotting and analyzing residuals.
- HSS-ID.B.6cFit a linear function for a scatter plot that suggests a linear association.

Big Idea:Students will analyze the use of function notation when describing what is happening in a function.

Cinderella's Slipper: Scatterplots, Residuals and Goodness of Fit

Algebra I

» Unit:

Our City Statistics: Who We Are and Where We are Going

Big Idea:Students explore the idea of Goodness of Fit for different data sets and learn to fit data that can be modeled with linear associations!

Writing Linear Functions (Day 2 of 2)

Algebra I

» Unit:

Battery Life

Algebra I

» Unit:

Multiple Representations: Situations, Tables, Graphs, and Equations

Big Idea:Will the digital devices run out of charge on the way to school? Students reason and make predictions based on a graph and compare the charge of a cell phone and a video game player.

HSS-ID.B.6a
