Data: Obtain two sets of 30 numerical data points, about two related things (work hours and salary, medicine dosage, and death rate, number of children and number of TVs, whatever you like; Data: Obtain two sets of 30 numerical data points, about two related things (work hours and salary, medicine dosage, and death rate, number of children and number of TVs, whatever you like.
You may use that data as one of your data sets, and obtain another set that relates to it. Give a link to the source of the data. you may use that data as one of your data sets, and obtain another set that relates to it.
Linear Regression: Perform linear regression on the two data sets. Type, write, or show the entire screen of output. (This involves choosing which data set is the explanatory (x) variable, and which is the response (y) variable; stick with that choice throughout!) Write the equation of the line in slope-intercept form, with the numbers in the right places. Linear Regression: Perform linear regression on the two data sets.

Graph: Make a graph that shows all of the data points and the linear regression line. Give the window used. Graph: Make a graph that shows all of the data points and the linear regression line. Give the window used.
Descriptive sentences: Write sentences giving the number called for and describing:
the slope of the linear regression line means in terms of your two variables, with numbers and units.
the y-intercept of the linear regression line means in terms of your two variables, with numbers and units.
the correlation coefficient and what it means, including if the relationship between your variables is positive or negative, and how strong the relationship is.
the coefficient of determination (r2) and what it means in terms of your two variables.Descriptive sentences: Write sentences giving the number called for and describing:
