The student will apply the data cycle (formulate questions; collect or acquire data; organize and represent data; and analyze data and communicate results) with a focus on representing bivariate data in scatterplots and determining the curve of best fit using linear, quadratic, exponential, or a combination of these functions.
A2.ST.2a
Formulate investigative questions that require the collection or acquisition of bivariate data and investigate questions using a data cycle.
A2.ST.2b
Collect or acquire bivariate data through research, or using surveys, observations, scientific experiments, polls, or questionnaires.
A2.ST.2c
Represent bivariate data with a scatterplot using technology.
A2.ST.2e
Determine the equation(s) of the function(s) that best models the relationship between two variables using technology. Curves of best fit may include a combination of linear, quadratic, or exponential (piecewise-defined) functions.
A2.ST.2f
Use the correlation coefficient to designate the goodness of fit of a linear function using technology.
A2.ST.2g
Make predictions, decisions, and critical judgments using data, scatterplots, or the equation(s) of the mathematical model.
A2.ST.2h
Evaluate the reasonableness of a mathematical model of a contextual situation.
