    SYLABUS EXTRACT:

    Understand, use and adapt altered measures of axial addiction (mean, median, mode) and aberration (range, interquartile range, accepted deviation), e.g. in comparing and allegory sets of data;

    Calculation of the beggarly and accepted aberration of a set of data (including aggregate data) either from the data itself or from accustomed n totals such as ?x and ?x2 , or ?(x?a) and ?(x?a)2 .

    To be written

    SYLABUS EXTRACT:

    (a) assemble a anticipation administration table apropos to a accustomed bearings involving a detached accidental capricious X, and account the expectation, about-face and accepted aberration of X (the notations E(X ) for apprehension (also referred to as accepted amount or mean) and Var(X ) for variance, are included);

    (b) use formulae for probabilities for the binomial and geometric distributions, and archetypal accustomed situations by one of these, as adapted (the notations B(n, p) and Geo( p) are included);

    (c) use tables of accumulative binomial probabilities (or agnate calculator functions);

    (d) use formulae for the apprehension and about-face of the binomial distribution, and for the apprehension of the geometric distribution.
