00:00:16.020 --> 00:00:16.760 align:middle line:90%
Hello.

00:00:16.760 --> 00:00:19.380 align:middle line:84%
In this short video, I'm going
to demonstrate how you can

00:00:19.380 --> 00:00:23.039 align:middle line:90%
run alpha reliability in SPSS.

00:00:23.039 --> 00:00:24.330 align:middle line:90%
Let's go ahead and get started.

00:00:24.330 --> 00:00:28.350 align:middle line:84%
In front of you, I have
the full textbook data set.

00:00:28.350 --> 00:00:31.080 align:middle line:84%
You'll notice this because it
has all the individual items

00:00:31.080 --> 00:00:31.920 align:middle line:90%
listed here.

00:00:31.920 --> 00:00:35.280 align:middle line:84%
For our purposes, we're
going to go ahead and run

00:00:35.280 --> 00:00:39.000 align:middle line:84%
the alpha reliability for
the prca24, the Personal

00:00:39.000 --> 00:00:41.982 align:middle line:84%
Report of Communication
Apprehension 24.

00:00:41.982 --> 00:00:43.690 align:middle line:84%
So let's go ahead and
see how this works.

00:00:43.690 --> 00:00:45.630 align:middle line:84%
First, I'm going to
go up here to Analyze.

00:00:45.630 --> 00:00:48.080 align:middle line:84%
I am going to drop
down here to Scale,

00:00:48.080 --> 00:00:51.750 align:middle line:84%
and then I'm going to click
over to Reliability analysis.

00:00:51.750 --> 00:00:53.700 align:middle line:84%
Once that pop-up
menu happens I need

00:00:53.700 --> 00:00:56.070 align:middle line:84%
to find the first item,
which in this case

00:00:56.070 --> 00:00:58.380 align:middle line:84%
is listed as communication
apprehension.

00:00:58.380 --> 00:01:01.350 align:middle line:84%
I can make this a little bit
larger so you can see why.

00:01:01.350 --> 00:01:03.460 align:middle line:84%
You'll notice I have the
title there, the item,

00:01:03.460 --> 00:01:05.700 align:middle line:90%
but it also says prca1.

00:01:05.700 --> 00:01:08.160 align:middle line:84%
That lets me know that
was the first item.

00:01:08.160 --> 00:01:11.980 align:middle line:84%
And then I can scroll all the
way down until I see prca24.

00:01:11.980 --> 00:01:14.640 align:middle line:84%
If I hit Shift on
my keyboard, I'll

00:01:14.640 --> 00:01:17.100 align:middle line:84%
be able to select
all of them at once.

00:01:17.100 --> 00:01:19.200 align:middle line:84%
And then I can just
click this arrow,

00:01:19.200 --> 00:01:21.210 align:middle line:84%
and it'll send all of
those items over here

00:01:21.210 --> 00:01:22.870 align:middle line:90%
to the Items box.

00:01:22.870 --> 00:01:26.250 align:middle line:84%
Now, I could have just as
easily clicked the first one

00:01:26.250 --> 00:01:27.580 align:middle line:90%
and then click the button.

00:01:27.580 --> 00:01:31.260 align:middle line:84%
Or I could have double-clicked
each individual item,

00:01:31.260 --> 00:01:33.336 align:middle line:84%
and that would have
done the same thing.

00:01:33.336 --> 00:01:34.710 align:middle line:84%
So again, there
are multiple ways

00:01:34.710 --> 00:01:37.274 align:middle line:84%
that you can send this
over to the Items box.

00:01:37.274 --> 00:01:39.690 align:middle line:84%
But this time I'm going to go
ahead and hit the first one,

00:01:39.690 --> 00:01:41.550 align:middle line:84%
hit the last one,
and click Shift.

00:01:41.550 --> 00:01:45.540 align:middle line:84%
And then all 24 items are
going to be right over here

00:01:45.540 --> 00:01:47.070 align:middle line:90%
in the Items box.

00:01:47.070 --> 00:01:50.160 align:middle line:84%
Now, for our purposes, when
it comes to the prca24,

00:01:50.160 --> 00:01:52.770 align:middle line:84%
you'll notice that the
alpha reliability is already

00:01:52.770 --> 00:01:53.770 align:middle line:90%
selected.

00:01:53.770 --> 00:01:57.960 align:middle line:84%
So all I have to do at
this point is click OK.

00:01:57.960 --> 00:01:59.350 align:middle line:90%
And there we have it.

00:01:59.350 --> 00:02:04.860 align:middle line:84%
Alpha reliability of 0.939,
and of course, 24 items.

00:02:04.860 --> 00:02:09.360 align:middle line:84%
And that is how you can run
alpha reliability in SPSS.

00:02:09.360 --> 00:02:11.742 align:middle line:84%
