Tip: Highlight text to annotate itX
Hello everyone. Welcome to the Lab 2 helper video.
Let's get started. I already logged into the virtual client through
Virtual Owl. You can see that this window I'm manipulating is the Virtual Owl window.
It's different than the desktop on my computer. So I am going to go ahead, go over here, and
start-up our statistics program. As you can see, I'm again adjusting this so
you can tell which one is my desktop versus which one is the remote host desktop.
So, I'm going to click "More Files" and then I'm going to find the folder in which I have
the data. Now, I don't see it because it is looking
for the wrong file-type. So what I need to do is go down here and change the file-type.
Click that. Click "Open" and give it a second. On this menu, you just need to click "Okay."
You don't need to change anything. As we can see here, this is some sample data
that I have that is similar to what you will be using in the lab. It's not the same, but
it is similar. It's important to have the assignment sheet
and the directions open while you work on this file, so make sure you have those open.
What I'm going to do is review what I am being asked to do and review the directions.
One of the first things to do is code your data. The first step in coding the data is
to go to the Variable View. In the Variable View, we are going to replace the name of
the variables with something that is easier for organizational purposes.
Make sure you be conscious about what is and is not allowed in the naming.
Now that I have done that, all of my variables are named more appropriately.
The next step in coding the data is to transform the words into numbers. Note the "cheat sheet"
that you have in your directions. Fortunately, there is an easy way to do this.
Highlight any column. Then, go up to the Edit menu. Select "Replace" and then, enter the
thing that you wish to replace. This example is for the word "Female." I know
by my coding sheet that all of the words "Female" need to be replaced with the number 1. So
I put "1" and then click "Replace All." And SPSS does the rest.
See how all of the words "Female" have been changed into 1's.
I can do this for any word that I need to do for the assignment.
Here I am changing the word "Male" to "2." And it is just that easy.
Now that I coded the data in the way I wanted to, I need to make sure that two other things
are changed correctly. I need to make sure that the Type and the Measurement Type of
my variables have been change appropriately. Here I am starting to change some thing from
Nominal to Ordinal and from String to Numeric. We way you do this is literally just click
on the measure or if it is the other one (Type), click next to it on the ellipse box.
As you can see, the data has not changed because I did it in the correct order, which is that
I have to code it first and then, change the measurement type.
Now I am checking the directions to make sure that everything has been done so far, before
it is time to run some descriptive statistics. To run the descriptive statistics, you go
to "Descriptive Statistics," "Descriptive,"and then select whatever variables you wish to
run them on. I am checking to see what I am going to need
for this particular assignment. Now, I select the variable and I move it over.
I can also click the options submenu and add anything else that I might want or anything
else I'm asked for on the worksheet. After I select what I want, I'm going to click
"Continue" and "Okay." In the new Output window, descriptive statistics
that I have just run will be present. I can use this information to then fill-in the worksheet
in the questions I have been asked. The next thing I have to do is run a Frequency.
To run a Frequency, I go back to my data, which is not in the Output window. After checking
exactly what variables I am going to need a frequency for, I go up to "Analyze," "Descriptive
Statistics," "Frequencies." And then I select whatever it is that I would
like, move it over, and then click the "Statistics" submenu.
Again, I can add all sorts of things. For this particular assignment, I don't need anything
extra, so click "Continue" and then, "Okay." And here I am at the Output window again with
all the necessary information to be able to fill-in for the assignment.
The other thing that is important for Virtual Owl is to make sure that you've saved your
worksheet on your actual desktop and not the remote host's desktop.
You can do this by when you click "Save," scroll up in the menu and you'll be able to
see your hard-drive versus the other hard-drives. If all else fails, you can always email it
to yourself or upload it straight from the web-browser used on Virtual Owl.
