Common Statistical Functions
   MAX
    – returns maximum of a range of cell values
   MIN
    –   returns minimum of a range of cell values.
   AVERAGE
    –   returns average or mean of cell values.
Statistical Functions
   MEDIAN
    – Returns middle value of an ordered array.
    – Unaffected by the outliers, thus most
      appropriate measure of central tendency
      when outliers are present in the data
   MODE
    – Returns the most frequently occurring, or
      repetitive, value in an array or range of
      data.
    – Not affected by outliers

Statistical Functions - Excel Hints
   The arguments should be numbers, names, arrays,
    or references that contain numbers.
   If an array or reference argument contains text,
    logical values, or empty cells, those values are
    ignored; however, cells with the value zero are
    included.
   If the data set contains no duplicate data points,
    MODE returns the #N/A error value.
   If there is an even number of numbers in the set, then
    MEDIAN calculates the average of the two numbers
    in the middle.

Compounding calculations in Excel




 FV function is used for the calculation of Compounding
                   problems in Excel
Formula




          - Obtained from Excel help
Arguments
   FV (rate, nper, pmt, pv, type)
    – Rate is the interest rate per period.
    – Nper is the total number of payment periods in an annuity.
    – Pmt is the payment made each period; it cannot change
      over the life of the annuity. Typically, pmt contains principal
      and interest but no other fees or taxes. If pmt is omitted, you
      must include the pv argument.
    – Pv is the present value, or the lump-sum amount that a
      series of future payments is worth right now. If pv is omitted,
      it is assumed to be 0 (zero), and you must include the pmt
      argument.
    – Type is the number 0 or 1 and indicates when payments are
      due. If type is omitted, it is assumed to be 0.

         FV function Arguments criteria
           Make sure that you are consistent about the
            units you use for specifying rate and nper.
             –    If you make monthly payments on a four-year loan at 12 percent
                 annual interest, use 12%/12 for rate and 4*12 for nper. If you make
                 annual payments on the same loan, use 12% for rate and 4 for
                 nper.

         cash you pay out, such as deposits to
          savings, is represented by negative numbers
         cash you receive, such as dividend checks, is
          represented by positive numbers.
                                                                   - Obtained from Excel help

Dollar Cost Averaging (DCA) -
definition
   An investment strategy designed to reduce volatility in which
    securities, typically mutual funds, are purchased in fixed dollar
    amounts at regular intervals, regardless of what direction the
    market is moving. Thus, as prices of securities rise, fewer units
    are bought, and as prices fall, more units are bought.

     As mentioned in your practical web page go to your
    favorite search engine and find out more about dollar
                    cost averaging (DCA)
DCA – Simple e.g.

   A person has invested 100 dollar/month
    in stock market by dollar cost averaging.
    The share price values of the stocks he bought for 6 months are given as
                               Month    Price per
                                         Share
                                 1           $8.20
                                 2           $8.25
                                 3           $8.30
                                 4           $8.35
                                 5           $8.40
                                 6           $8.45


   What is the value of his total investment after 6 months ?
