THIS COURSE: Algebra I
    is
  about             the study of the rules of operations and relations, and the constructions and concepts arising
                    from them, including terms, polynomials, equations and algebraic structures




 1.   How are algebraic expressions and equations used to solve real world problems?
 2.   What is the relationship between a line and its graph, slope, intercepts, and table of values?
 3.   How is a function, in all its forms, used to investigate relationships between quantitative data?
 4.   How is a linear system used to solve real world problems?
 5.   What are the different ways to simplify a polynomial expression?
 6.   What is the most effective way to solve a given quadratic equation?
 7.   How is a line or curve of best fit used to make predictions about a set of data?
 8.   How are measures of deviation and z-scores used to describe and analyze a set a data?

 A z-score (standard score) is a
  measure of position derived from
  the mean and standard deviation of
  data.

   A z-score derived from a particular
    data value tells how many standard
    deviations that data value is above
    or below the mean of the data set. It
    is positive if the data value lies
    above the mean and negative if the
    data value lies below the mean.
