REFERENCE CARD

1.- Introduction

Graphs and statistics (SDG) is a powerful software and easy to use.

Through menu you can create and edit variables, manage files, describe

variables in statistical form, perform simple and multiple regression,

analysis of variance for experimental designs, two-dimensional and

three-dimensional graph equations, build scatter diagrams and

histograms. It may also generate random variables, transform variables,

variables to convert various formats to interact with various programs,

create pie charts, bar, etc.

All results are easy to interpret and the user requires only minimal

knowledge of statistics.

SDG consists of several modular programs that interact with each other

through interactive menus with the user.

All modules are scheduled in TURBO BASIC with some subroutines into

machine code that makes some processes more efficient. All programs are

unprotected and can be listed and or modified.

With SDG you can graph their monthly expenses, statisticians calculate

averages and other complexes, pooling their data in tables and get

immediate histograms, to differentiate between products, predicting its

sales or expenses, graph complex mathematical functions, and so on.

The configuration that requires you to use SDG in a

physical ATARI:

1) A computer ATARI with a minimum of 48 Kb. RAM

2) A floppy drive ATARI

3) A diskette SDG (A and B sides system or two separate floppy disks)

with modular programmes.

4) A blank floppy disk to store files: variables (data), graphics,

tables, etc.

5) A printer EPSON RC-220 or equivalent, optional.

6) An optional printer plotter ATARI 1020 for three-dimensional

graphics.

The configuration that requires you to use SDG in emulation

with Atari800Win Plus:

1) Load Image SDG-side-A.atr in the Disk Drive 1

2) Load Image SDG-Data.atr in Disk Drive 2

3) Reset emulator and disable BASIC. When you start the program, choose

Option 2

How do I load onto your computer SDG ATARI?

1) Turn on the drive 1 (and 2 drive in case of using two Drives)

2) Insert the SDG system disk by side A (or Diskette 1 if the system is

recorded in two separate floppy disks).

3) Turn on your computer pressing OPTION

4) Choose the appropriate option on the screen and follow the

instructions below.

2 .- Variable EDITOR Module

Purpose: To create, modify or add data from a variable. The variables

must be created or modified one by one, and before editing another

variable, the above is recorded on the disk data.

3. Statistics descriptive Module

This module can describe any statistically variable hospitalized with

options from 1 to 6 Editor variables. Handing the following

information:

a) Table of frequencies with

complete

and

absolute

frequency

percentage,

and

accumulated and partial.

b) Histograms of frequency

partial and cumulative.

c) Position parameters:

Arithmetic mean, Geometric

mean, median, mode (one or

more), Percentiles, Minimum

and maximum value.

d) Dispersion parameters:

Variance, Standard deviation,

rank, and coefficient of

variation.

e) Bias Pearson

f) kurtosis percentile

4. Regression Module

The module is loaded from the Main Menu B-side of the disk system.

Insert the disk data and press <return>, you'll see that in diquete

data are recorded by the two variables you: YEARS and PROD. Press "E"

to finish watching the directory and enter as it prompted the dependent

variable and the independent variable PROD YEARS. Then choose the menu

screen the regression model most appropriate, or adjust all models and

then pick the best of them according to the results (Coefficient of

Determination and analysis of variance).

5. Andeva Module (design of experiments)

The module calculates and

constructs the table

Analysis of Variance

(Andeva) to study the

existence of significant

differences between

different treatments. You

have the option of bringing

their design of experiments

to one of the following

models:

a) fixed Treatments with

complete randomization.

This model is used when

the treatments were

randomly assigned to

the

experimental

units.

b) Model full block.

When there is no

uniformity for all

experimental units,

can be separated into

blocks,

each

with

characteristics

uniform. So for

example, a soil

fertility of different

stripes, each of the

strips to form a bloc

passes, and within

each bloc, the

experimental units are

assigned randomly.

c) Random Model with

factorial structure .

When each treatment

consists of the variation

of 2 or more factors, the

design has factorial

structure. By example, if

one takes 2 factors, the

first with two different

levels and the second

with

three

levels,

treatments

will

trained 2 x 3 = 6.

6. Modules for graphics

The graphics are the most

common statistical bar

(simple and grouped) and

circulars

(sectoral

cakes).

Any variable can be created

with SDG graficada with this

module, provided it is

within their capabilities.

The pie charts require a

maximum of one variable,

however, the bar allowed up

to three variables (all with

the same number of data for

each figure represents a

bar). These graphs can be

recorded and printed on paper.

This module also allows the variables are entering through the keyboard

directly without passing through the publisher of variables.

Another interesting option is

to graph functions of three

variables

three-

dimensional shape.

Observations: These graphics

capability are not creción

the author of SDG. The bar

charts and circulars come

from the software

"GRAFIQUELO", and three-

dimensional graphics are

known as "Z_PLOTTER". These

programs have been adapted to

use modular SDG.

7. Printing Module

It serves to recover on the screen and / or any file printer (graphic

or not) product of the process of recording them from any form of SDG.

8. Module for Files Edition

Lets see any floppy directory, rename, delete, protect or unprotect

files. Also used to format disks. In other words, it avoids having to

leave the DOS to conduct these operations.
