in this video we will introduce you to SPSS we will introduce you to the
interface the user interface and we will discuss some toolbars and drop down
menus and how commands are organized and then some hands-on training with SPSS
when you launch SPSS it opens up with two simultaneous windows the first one
for now you can just simply click on close and look at the more important
window which is lying just behind it essentially this user interface of this
particular window is the data editor window where you can see the data would
be in rows and columns rows representing to each respondent and the columns are
dedicated to variables and at the same time you see toolbars through which you
can run the analysis but the real essence of the program is hidden
behind these drop-down menus everything to do with data is under data
transformation of data into transform statistical analysis under analyze and
graphing and charting into graphs when we open a dataset this window will be
filled with data where rows will represent each observation and the
variables will be in columns now let's open a dataset to see how it looks like
again we are referring to the same data set from University of Texas when the
data set is displayed in the data editor window you would notice that the
variables are in columns and you can see the column names each row represents a
particular course in the data set so this Row two would represent one course
taught by a visible minority professor whose 36 years old she's female and the
beauty score is point two nine she receives the teaching evaluation of
point three seven and so on and so forth the other very interesting part of SPSS
is its ability to help you understand how your data is organized you can look
at the variable view by clicking on variables view and the variable view you
see each variable listed in a separate their type is it a string or a character
variable or numeric variable the display characteristics if the variable
has a label if it's a categorical variable it if it has n values if they
were missing information in it and at the same time some others SPSS specific
definition or types of variables and if you're familiar with data mining you
would notice that it defines a variable role as either input or target now you
see the syntax window every time you ran run a command in SPSS by executing that
command it runs a syntax which you can paste in the syntax window and this is
the best way to keep track of what of your work and it offers you the ability
to reproduce your analysis by just highlighting the the code and pressing
the Run button your output is sorted in and placed and organized in the output
window all graphical and tabular data or output is carefully organized you have a
legend here and all the output in detail here
now let's launch SPSS and get some hands-on training we will open the
teachings rating data by clicking on this icon on the user on the toolbar
click teaching gradings and then click open the data set is displayed in the
data editor and the variable view is available with this toggle here as you
can see the variable view and the data view at the same time you can
you will notice that SPSS opens the output window that becomes the home for
all the analysis that you will do that will be stored in the output window
let's say we would like to compute the descriptive statistics for some of the
variables which are continuous variables so we click on analyze descriptive
statistics and then click on descriptive and then select age a teaching
evaluation score and then click from option C we have the means
and deviation minimum and maximum selected to continue and say okay as
soon as we say okay the output is presented here the minimum age is 29 the
maximum age is 73 and the average age is 48 point three seven with the standard
deviation at nine point eight another way of doing the same is to use the
syntax we click on this icon to get the last dialog box we use and instead of
clicking on OK I would click on paste to paste the syntax in the syntax window
you could see that this is the command that SPSS actually executed another way
of getting the same output is to highlight this command and say run and
it will run the selection and you can see the same output is reproduced this
time by clicking on the syntax let us conclude this video by generating a
histogram differentiated by gender we click on graphs we click on chart
builder we click on histogram click on this or drag it here it says the
distribution variable which is teaching evaluation we put it here and it's split
variable let's say gender just drag it here and now we have the option of
clicking on OK or paste we just say ok and your histogram is ready and this
displays the histogram for all the distribution of teaching evaluation
scores for males separate from females
