Spss and software Application

⚫STATISTICS derived from the
New Latin statisticum collegium ("council of state") Italian word
statista ("statesman" or "politician").
⚫It was introduced into English in 1791 by Sir John Sinclair when he
published the first of 21 volumes titled Statistical Account of Scotland.

the quantiles of the normal distribution.
SEQUENCE
Produces a plot of one or more variables by order
in the file, suitable for examining time-series data.

TIME SERIES: AUTOCORRELATIONS
• Calculates and plots the autocorrelation function (ACF) and
partial autocorrelation function of one or more series to any
specified number of lags, displaying the Box-Ljung statistic at each
lag to test the overall hypothesis that the ACF is zero at alllags.

TIME SERIES: CROSS-CORRELATIONS
Calculates and plots the cross-correlation
function of two or more series for positive,
negative, and zero lags.

TIME SERIES: SPECTRAL
• Calculates and plots univariate or bivariate periodograms and
spectral density functions, which express variation in a time series as
the sum of a series of sinusoidal components. It can optionally save
various components ofthe frequency analysis as new series.

Advantages
 SPSS offers a user friendliness that most
packages are only now catching up to.
 It is popular, and though that is certainly not
a reason for choosing a statistical package,
many data sets are easily loaded into it and
other programs can easily import SPSS files.

Disadvantages
 For academic use SPSS lags notably behind SAS, R
and even perhaps others that are on the more
mathematical rather than statistical side for modern
data analysis.
 Its menu offerings are typically the most basic of an
analysis and sometimes lacking even then, and it
makes doing an inappropriate analysis very easy.
 It is expensive, sometimes ridiculously so, and even
when you do buy you're really only leasing, and its
license is definitely not user friendly.
 There are often compatibility issues with prior

3. YYYY/MM/DD ---2018/03/12

Numeric type of variable
6
and Date
• We use it for variables {other than ID ,Text
variables} which we insert our data using NUMBER .
• Eg 1 = Yes (for “Yes” response we insert “1”)
2 = No (For “No” type response we insert “2”)

Create numeric type of variable using two ways
7
1. Using “FIELD PICK LIST” MENU from epi data window
 From “Field pick list menu” click on “Numeric” then decide the number of
digits before and after decimal points.
Eg. If we want no digits after decimal points we make digits after decimal
points as= “0”

CON’T…
8
And we make before decimal points based on our interest,
(that is based on our sample size).
For example----- if our sample size is 100, we make it 3. i.e field
length is 3 (# # #), for 50 sample, we make it as “2”, i.e the field
length is 2 (# #).

Second method to define Numeric type of variables
9
2. Using short cuts
Click shift+# on your computer
E.g for 200 we type as (shift 3x i.e ###)

After finish “QES”file “align fields”
0
• To make our data entry form more attractive need to align
fields
• Select “EDIT” Menu from epi-data, click “Align fields”
N.B. first click on the variable with long variable label.

Step 2. CREATE “REC” FILE
1
First save our “QES file” on the folder we create before and
label it.
Second click “Make data file” at epi-data menu, then select “Make
data file”

Step 3. Create “CHECK FILE”
In this part we Set rules and commands for our data
1. Define range and legal values for continuous type
of variables (e.g. age, income…). message.
14

CHECK…CON’T…
3
2. Set “MUST ENTER & REPEAT” commands
We will not pass any fields without entering data if we set “Must
enter commands”
193

CHECK…CON’T…
4
3. “SHOW” & “TYPE COMMENT” COMMANDS
This commands help us during data entry by showing us list of
responses to chose among the lists and type entered response for
each respondents.
194

CHECK…CON’T…
4. Define variable labels for “categorical type of variables” (1=male,
2= Female). N.B. IF the categorical variable is made of two words it
must put under double quotation.
e.g. marital status---1. “never married”--- Two words

Cont’d…
• 5. Set “SKIP” Commands (IF the answer for question “A” is “No” then
skip question number “B” and go to question number “C”).
Select the question where this commands setted, then Click on
“edit” in check file, then click enter and type the followings :-
AFTER ENTRY
•IF A <> 1
THEN
GOTO C
• ENDIF

Step 4. EXPORT “EPI-DATA” FILE TO SPSS
7
 Open your epi-data file, select “Export data” from epi-data window, select
SPSS, click ok
 Second select and open spss data file from folder where your epidata qes ,rec
and check files found together under the same folder.
 Third from opened spss window click on “RUN” and select “run all”
 Fourth save the new exported spss data.

What is Endnote?
Create and manages reference lists.
Enables searching of reference "libraries" by author, keyword, date,
etc.
In Word documents, automatically formats the references in APA
format for you.
Many online databases allow references to be sent directly into
Endnote.
Can also store and organise images, graphs, tables, etc.

Entering References:
Three ways:
(a) Manually type them in.
(b) Save files from online search facilities.
(c) Search online databases through Endnote and retrieve
the references directly to your Endnote library

Manually Entering References (1)
(a) To start a
new Endnote
library,
click on "file",
then "new"
(b) This box
appears -
enter a
filename for
your new
library

Your new
reference library
(empty at the
moment...)

To enter a
reference, go
to "New
Reference"

Enter details of the
reference in the
relevant "fields"
(Optional how
many you use).
Select which
type of
reference you
want (journal,
book, comic,
etc.)

Click on "Close
Reference" to finish
entering this
particular reference.
Click on "New
Reference" to add
another reference.

A completed reference library:

Searching a reference library:

Information about References:
Each Reference:
Stores all the information needed to cite it in a reference list
(e.g. in a lab report or essay).
Within a library, each reference has a unique record number
which cannot be changed.
The fields (author, year etc) can be modified, deleted or new
ones added.
There are many reference types (book, journal article, newpaper
article, chart, equation, etc...)

Downloading references from the Web of Knowledge:
1. Go to library website and select "online resources":

2. Scroll down to "Web of Knowledge":

3. Click on "Web of Knowledge":

5. Tick the references you want to retain.

6. Click on "Save to Endnote...".

References are exported to your chosen Endnote library:
NB: shows only the new references (click on "Show all
references" to see earlier entries).

Downloading citations from ScienceDirect:
1. Go to library website, click on ScienceDirect:

2. Perform your search, then click on "export citations":

3. Pick "citations only" or "citations and abstracts":

5. Entries are added to the chosen Endnote library (this
time, with abstracts as well):

Endnote adds an extra menu within Microsoft Word:

Referencing conventions:
In essays and lab-reports, all cited work must be properly
referenced, by a reference in the text (author surname and date of
publication), and an entry in a reference list that contains complete
details of each reference:
In the text: "Field and Hole (2003) give lots of useful advice". Or
"Learning statistics has been shown to be easier than people think
(Field and Hole, 2003)".
In the reference list: Field, A. and Hole, G. (2003). How to design and
report experiments. London: Sage.
Problem is that the conventions for this differ slightly between
journals (although most use "A.P.A. format").

Start Word and open the document you are writing.
To cite a source, position the cursor where you want the reference to
appear, then click on "Insert Selected Citation":
Inserting references in the text:

Endnote
(a) adds the reference in the text;
(b) adds the full reference to a reference list at the end of the
document
- correctly-formated and in alphabetical order!
This is a load of rubbish I'm writing in order to show you how to use "Endnote"
(Duck and Mouse 2007). Here's some more tosh that I've just typed (Sooty and
Sweep 2007), and yet more (Lala, Tinky-winky et al. 2007).
Duck, D. and M. Mouse (2007). "Our living hell: life as prisoners in Disneyland."
Animal Behaviour 29(5): 179-199.
Lala, Tinky-winky, et al. (2007). "Effects of the media on body-image in telly-
tubbies." Journal of banal research 99: 201-203.
Sooty and Sweep (2007). Hands up: we don't have a leg to stand on. Congleton,
Garbage Books Inc.

Formatting the Bibliography:
You can format the references in different styles by choosing
‘Format Bibliography’ from the Endnote menu.
Use "APA 5th" as your output style

More Information, and how to get Endnote:
Endnote is installed on all campus PC's.
For your own computer, you need to purchase a copy.
