Alg1.3 Two-variable Statistics
Lesson 1
- I can calculate missing values in a two-way table.
- I can create a two-way table for categorical data given information in everyday language.
- I can describe what the values in a two-way table mean in everyday language.
Lesson 2
- I can calculate values in a relative frequency table and describe what the values mean in everyday language.
Lesson 3
- I can look for patterns in two-way tables and relative frequency tables to see if there is a possible association between two variables.
Lesson 4
- I can describe the rate of change and $y$-intercept for a linear model in everyday language.
- I can draw a linear model that fits the data well and use the linear model to estimate values I want to find.
Lesson 5
- I can describe the rate of change and $y$-intercept for a linear model in everyday language.
- I can use technology to find the line of best fit.
Lesson 6
- I can plot and calculate residuals for a data set and use the information to judge whether a linear model is a good fit.
Lesson 7
- I can describe the goodness of fit of a linear model using the correlation coefficient.
- I can match the correlation coefficient with a scatter plot and linear model.
Lesson 8
- I can describe the strength of a relationship between two variables.
- I can use technology to find the correlation coefficient and explain what the value tells me about a linear model in everyday language.
Lesson 9
- I can look for connections between two variables to analyze whether or not there is a causal relationship.
Lesson 10
- I can collect data, create a linear model to fit the data, determine if the linear model is a good fit, and use the information from my linear model to answer questions.
