variables?
Response Variables, Explanatory Variables, Independent
Variables, Dependent Variables, Scatterplot, Overall
Pattern, Deviations, Form, Direction, Strength, Clusters,
Positively Associated, Negatively Associated, Linear
Relationships, Correlation, Least-Squares Regression,
Regression Line, Slope of LSRL, Intercept of LSRL,
Coefficient of Determination, Residual, Roundoff Error,
Residual Plot, Influential Observations
The weight of soap depends on the number of days it had
been used. Thus dependent variable(y) is weight of the soap
and independent variable is the number of days (x). The
computation from minitab is as follows:
Predictor Coef SE Coef
T
P
Constant 123.141 1.382 89.09 0.000
Day
-5.5748 0.1068 -52.19 0.000
S = 2.94921 R-Sq = 99.5% R-Sq(adj) = 99.5%

Identify the slope, y-intercept, the values of s and r2.
Write out the least squares regression line.
We will continue with intepreting computer regression
outputs and continue where we left off from previous day.
Clear up any misconceptions students may have. What are
they still struggling with?

Work Session
Students will work on 3.2 Least squares regression quiz
independently. They will have 20-30 minutes to complete
this quiz. When students are finished, they will be given
the study guide for their test on Tuesday and will need to
start working on it. They will be provided time tomorrow to
finish it and ask any questions.
Clear up any misconceptions students may have. What are
they still struggling with?

Students are to get out their calculator cheat sheet, and
their interpreting in context cheat sheet.
Students will work on their review either collaboratively or
individually.
Discuss any misconceptions they may still have.
