REGRESSION PROJECT WORKSHEET:

  1. Did the student show the material learned in this course can be useful in a topic that is relevant to the individual students?
(explain in one sentence how your data is either interesting to you personally OR related to you major of study)
EX: I am a Bio major and I am interested in dolphin populations
  1. Is it cited if the source of the data is from the library or internet versus data that is collected in an experiment?
(Explain how you collected the data OR Give internet address here.
EX: data from www.mccc.edu/~porterr
  1. Did the student identify the variables and which would be considered independent and dependant? Is the data given?
Label the x and y variables. Give Nine Data points here.
X:
Y:
  1. Is the data plotted in an appropriate window? Are regressions graphed with data plots?
Label x and y axis, show what you get after zoomstat. Put all the regressions on the same graph.
  1. Did the student identify the best regression. What makes the regression the best?
LinReg: a=_____ b=______r2=______(good?)_____
Make sense? Why?______(Best?)______
QuadReg: a=_____ b=______c=______r2=______(good?)_____
Make sense? Why?______(Best?)______
CubicReg: a=_____ b=______c=_____ d=______r2=______(good?)_____
Make sense? Why?______(Best?)______
QuartReg: a=_____ b=______c=_____ d=______e=_____ r2=______(good?)_____
Make sense? Why?______(Best?)______
ExpReg: a=_____ b=______r2=______(good?)_____
Make sense? Why?______(Best?)______
LnReg: a=_____ b=______r2=______(good?)_____
Make sense? Why?______(Best?)______
sinReg: a=_____ b=______c=_____ d=______r2=______(good?)_____
Make sense? Why?______(Best?)______
(mark the two that are the best)
  1. Did the student evaluate (predict) and solve for a value of one of the polynomial regressions.
Which two regressions did you pick? ______and______
What value are you plugging in for x______
What y-values did you get?______and ______
What y value are you predicting?______(y2=value use intersection)
What x-values did you get?______and ______
  1. What is the end behavior for the polynomials?
Which regressions did you pick? ______
What is the left end behavior?______Right end?______
  1. Did the student find the zero for the cubic regression?
Did the student find the extrema (vertex at x=-b/(2a))for the quadratic regression?
  1. Did the student find the exponential regression’s rate of growth or decay. (Find ln(b) and write as percent)
Which is it? Growth(b is positive) or Decay(b is negative)
  1. Where is the asymptote for the exponential regression? (calculator uses only y=0, but you may want another)
What is the end behavior for the exponential?
What is the left end behavior?______Right end?______
  1. Did the student discuss the asymptote, domain, and range for LNREG?

Asypmtote:______
Domain:______
Rnage:______
  1. Did the student find the period, Amplitude, and phase shift for the sine regression?
Sin reg a=_____ b =_____ c=_____ d=_____
Amplitude: (|a|)______
Period: (2pi/b)______
Phase Shift (-c/b)______
Raised:( d)______
  1. Did the student find all the solutions to a regression value just above or below the extrema?
Value desired: (y2=)______Period:______
2 distinct solutions: (intersection method) s1:______s2: ______
All solutions ______(add n*period to s1)
______(add n*period to s2)
  1. For the best regression, Where the regions of increasing and decreasing identified?
List Maximums:______
List Minimums:______
Increasing(between min and max):______
Decresing (between Max and min ):______
  1. Were two reviews written for classmates? Were two reviews of this project done by classmates? (just list their names)
Who is reviewing you?______and ______
