KWIKSTAT is a scientific statistical analysis system complete with      
graphics.  You can import ASCII files, dBase III files or build your own
databases.  KWIKSTAT is menu-driven, with six separate modules:         
~ DATA    -- Create a database, enter and edit data.                    
~ REPORTS -- Export data to another program; display the structure of a 
selected database and access DOS without exiting.                       
~ STAT1   -- Descriptive statistics and graphical representations such  
as histograms, scatterplots and box plots.                              
~ STAT2   -- Explore comparative statistics with t-tests on paired or   
matched data and one way analysis of variance (ANOVA).                  
~ STAT3   -- Perform simple linear and multiple regression analyses.    
~ STAT4   -- Deal with various methods to analyze categorical data, as  
opposed to measured data.

        A hard disk is recommended for using KWIKSTAT, although individual
        programs can be run from a floppy disk. The procedure described
        here loads this KWIKSTAT supplemental program on the hard disk
        drive C:, in a subdirectory named C:\KWIKSTAT.

        Place the KWIKSTAT SIMULATIONS DISK in drive A:. Make disk A: the
        default drive, by entering the command:


        (or you can use B: if your disk drive does not fit disk A:) Next,
        enter the command:


        (There is a space after the command KSLOAD). If your Kwikstat
        programs are on another disk drive or directory, change the command
        to reflect its location. You need to have version 2.10 or higher of
        Kwikstat, with EXE files dated 10-1-90 or later for the menu to
        work properly. Install the Kwikstat basic modules BEFORE installing
        any supplemental program.

        Place the KWIKSTAT SIMULATIONS disk in drive A: and the disk where
        you want it to reside in drive B:, and enter the command:

        A>KSLOAD B:\

        The B: disk must have the files BRT70EFR.EXE, KSMENU.INI and
        KWIKSTAT.HLP on the disk.  Also, make sure the disk has enough
        space for the copy to take place (about 80K).


        From the hard disk prompt "C", get into the KWIKSTAT directory
        using the command:

        C>CD \KWIKSTAT

        To begin KWIKSTAT, enter the command:


        The SUPPLEMENTAL program will appear on the Kwikstat menu. If it
        does not, please check to see that you have performed the
        installation properly.


        If it exists, print the file LATENEWS.DOC to get the latest
        information on Kwikstat. It may include information on new features
        or changes not included in this manual. Please check the main
        Kwikstat manual for information on monitor and path setup
        procedures and error codes.


        The Kwikstat Data Generation and simulation module is used to
        generate sample datasets for Kwikstat and to display simulation of
        some common statistical concepts. The screen for this module is
        illustrated below:<$&menu[v]>


        This option allows you to create Kwikstat (dBASE) data sets from a
        Normal, Uniform or Exponential distribution. You will be asked to
        specify the number of variables (columns in the database) to
        generate. Then for each variable, you must specify if it is to be
        from a Normal, Uniform or Exponential distribution.

          Kwikstat Simultations Module

        If the data is to be from a Normal Distribution, you must specify
        the mean and standard deviation of the variable. If the data is
        from a uniform distribution, you will be asked to specify the
        minimum and maximum of the distribution. You can examine the
        generated data sets in the Kwikstat Descriptive statistics module.
        See also option E to display a list of the dataset..


        The 95% Confidence Interval simulation shows visually the meaning
        of a 95% confidence interval. That is, if you take 100 samples from
        a population and calculate a 95% C.I. for each sample, you would
        expect about 95 of the 100 C.I. ranges to include the actual mean
        of the population.

        In this simulation, 100 samples of size 30 are drawn from a
        normally distributed distribution and a 95% C.I. is calculated for
        each sample. The true mean of the population is plotted
        horizontally on the screen. Each C.I. is plotted vertically on the
        screen so you can visually see if the range of the C.I. covers the
        true population mean. All 100 C.I.'s are plotted and a summary of
        how many covered the mean is displayed on the screen. To see what
        is meant by "about 95" will cover the mean, repeat this simulation
        several times. You will see that the number covering the mean will
        range from the 80s to 100, but will average about 95 over a period
        of trials.


        The Central Limit Theorem states that if samples of size n are
        taken from a population with an arbitrary distribution, the
        distribution of the means of the samples approaches normality as
        the size of the (n) sample increases. NOTE:If you are using a PC
        with an 8088 chip and no math co-processor, the generation of the
        Normal population will take as much as 2 to 3 minutes.

        In this demonstration, a population of 500 points is generated from
        either a Normal, Uniform or Exponential distribution. Then, 100
        samples of sizes 2, 3, 5, 10 and 30 are taken from the population.
        A histogram of the original population is displayed on the left
        side of the computer screen and a histogram of the sample is
        displayed on the right side of the screen. As each sample is
        displayed, you can see how the larger sample size makes the right
        side histogram approach a bell-shape. Also, as the sample size
        increases, the spread of the histogram gets smaller (the standard

        When you flip a fair coin, you would expect to get about the same
        number of heads and tails over a long period of time. This
        simulation automates 100 coin tosses and graphs the results. You
        should repeat this simulation a number of times to see how the
        graph varies for different series of flips.


        This option allows you to display the contents of a database to the
        screen. This is the sample as the "Kwiklook" option in the DATA
        module. Its purpose here is to allow you to example databases that
        you have created in this module without having to go to another
