(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 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 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: 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. 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?)_______ (mark the two that are the best)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 ___________________ What is the end behavior for the polynomials? Which regressions did you pick? ___________________ What is the left end behavior?________________________ Right end?___________________ 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? Did the student find the exponential regressions rate of growth or decay. (Find ln(b) and write as percent) Which is it? Growth(b is positive) or Decay(b is negative) 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?___________________ Did the student discuss the asymptote, domain, and range for LNREG? Asypmtote:_______________________ Domain:____________________________ Rnage:____________________________ 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)_____________________________  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) 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 ):_____________________________________________ Were two reviews written for classmates? Were two reviews of this project done by classmates? (just list their names) Who is reviewing you?____________________________ and ________________________ Notes for review 1: Notes for review2: 16. Was a presentation done? _____Was the presentation persuasive and interesting?17. Was the project handed in on time? Due date is the date of the presentations.
