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.
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 that represents a situation.
9
I can look for connections between two variables to analyze whether or not there is a causal relationship.
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.
