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.

INSTALLING KWIKSTAT SUPPLEMENT ON YOUR HARD DISK
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:
C>A:
(or you can use B: if your disk drive does not fit disk A:) Next,
enter the command:
A>KSLOAD C:\KWIKSTAT\
(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.

FLOPPY DRIVE INSTALLATION
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).
INSTRUCTIONS FOR OPERATION
From the hard disk prompt "C", get into the KWIKSTAT directory
using the command:
C>CD \KWIKSTAT
To begin KWIKSTAT, enter the command:
C>KS
The SUPPLEMENTAL program will appear on the Kwikstat menu. If it
does not, please check to see that you have performed the
installation properly.
LATENEWS
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.
DATA GENERATION AND SIMULATION
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]>
A)GENERATE DATA SETS
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.

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..
B)95% CONFIDENCE INTERVAL SIMULATION
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.
C)DEMONSTRATE CENTRAL LIMIT THEOREM
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
deviation).
The demonstration will automatically cycle through the 5 sizes of
samples. To cancel the demonstration, press the Esc key. This will

cause the demonstration to stop once the current sample has been
displayed.
D)FLIP A COIN DEMONSTRATION
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.
E)LIST VALUES FROM A DATABASE TO THE SCREEN
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
module.
