00:00:16.000 --> 00:00:16.900 align:middle line:90%
Hello.

00:00:16.900 --> 00:00:19.060 align:middle line:84%
In this short video, I'm
going to introduce you

00:00:19.060 --> 00:00:22.645 align:middle line:84%
to how to run descriptive
statistics using SPSS.

00:00:22.645 --> 00:00:24.520 align:middle line:84%
Now, the data set that
I have in front of you

00:00:24.520 --> 00:00:28.480 align:middle line:84%
is what is called the
Textbook Dataset Shortened.

00:00:28.480 --> 00:00:30.040 align:middle line:84%
Basically what I
have done is I've

00:00:30.040 --> 00:00:34.215 align:middle line:84%
gone through and gotten rid of
all of the individual items.

00:00:34.215 --> 00:00:36.340 align:middle line:84%
So it's basically, if you
look at the full dataset,

00:00:36.340 --> 00:00:39.970 align:middle line:84%
it's everything that was at the
far right end of the dataset.

00:00:39.970 --> 00:00:42.580 align:middle line:84%
It just makes it a little bit
shorter and a little bit easier

00:00:42.580 --> 00:00:43.820 align:middle line:90%
to work through.

00:00:43.820 --> 00:00:45.250 align:middle line:84%
So what we're going
to do is we're

00:00:45.250 --> 00:00:46.600 align:middle line:84%
going to go ahead and
run some descriptive

00:00:46.600 --> 00:00:48.550 align:middle line:84%
statistics on this
variable right here,

00:00:48.550 --> 00:00:51.880 align:middle line:84%
Big CA, or the complete
composite score

00:00:51.880 --> 00:00:54.410 align:middle line:90%
for communication apprehension.

00:00:54.410 --> 00:00:57.110 align:middle line:84%
So here's how you go ahead and
run descriptive statistics.

00:00:57.110 --> 00:00:59.530 align:middle line:84%
I'm going to come up here
to Analyze, Descriptive

00:00:59.530 --> 00:01:02.050 align:middle line:90%
Statistics, Frequencies.

00:01:02.050 --> 00:01:03.610 align:middle line:84%
Once the pop-up
menu is open, I'm

00:01:03.610 --> 00:01:06.794 align:middle line:84%
going to go ahead and
locate that Big CA.

00:01:06.794 --> 00:01:07.960 align:middle line:90%
So I'm going to scroll down.

00:01:07.960 --> 00:01:10.240 align:middle line:84%
Now I know just because
of when I labeled them,

00:01:10.240 --> 00:01:13.420 align:middle line:84%
I labeled Big CA as
communication apprehension

00:01:13.420 --> 00:01:15.730 align:middle line:90%
total in the Variable View.

00:01:15.730 --> 00:01:17.870 align:middle line:84%
So I can go ahead
and click on that,

00:01:17.870 --> 00:01:20.890 align:middle line:84%
and I'm going to send that
over to the Variables box.

00:01:20.890 --> 00:01:24.032 align:middle line:84%
Then I want to go and click
on the Statistics button.

00:01:24.032 --> 00:01:26.240 align:middle line:84%
And there's a range of
different types of statistics.

00:01:26.240 --> 00:01:29.500 align:middle line:84%
So let's look at a few over here
in Central Tendencies, which is

00:01:29.500 --> 00:01:31.580 align:middle line:90%
this upper right hand corner.

00:01:31.580 --> 00:01:33.580 align:middle line:84%
So I'm going to click
Mean, Median, and Mode.

00:01:33.580 --> 00:01:35.659 align:middle line:84%
Then I'm going to come
down here to Dispersion,

00:01:35.659 --> 00:01:37.700 align:middle line:84%
which is down here in the
lower left hand corner.

00:01:37.700 --> 00:01:40.990 align:middle line:84%
I'm going to click on Standard
Deviation, Range, Minimum,

00:01:40.990 --> 00:01:41.570 align:middle line:90%
and Maximum.

00:01:41.570 --> 00:01:43.570 align:middle line:84%
And then last thing, I'm
going to come over here

00:01:43.570 --> 00:01:44.450 align:middle line:90%
to Distribution.

00:01:44.450 --> 00:01:47.225 align:middle line:84%
I'm going to click on that
Skewness and Kurtosis.

00:01:47.225 --> 00:01:49.630 align:middle line:84%
Then I'm going to
click Continue.

00:01:49.630 --> 00:01:52.390 align:middle line:84%
Now one thing I want you to
be aware of-- at this point,

00:01:52.390 --> 00:01:55.820 align:middle line:84%
the Display Frequencies
Tables box is checked.

00:01:55.820 --> 00:01:57.730 align:middle line:84%
If I keep that
checked, it's going

00:01:57.730 --> 00:02:00.640 align:middle line:84%
to give me a basic
rundown of how many people

00:02:00.640 --> 00:02:02.500 align:middle line:90%
had each individual score.

00:02:02.500 --> 00:02:04.980 align:middle line:84%
For our purposes,
not very useful.

00:02:04.980 --> 00:02:06.730 align:middle line:84%
So I'm going to go
ahead and uncheck that.

00:02:06.730 --> 00:02:08.800 align:middle line:90%
And then I can just click OK.

00:02:08.800 --> 00:02:10.780 align:middle line:84%
Immediately, as you
can see over here,

00:02:10.780 --> 00:02:15.160 align:middle line:84%
the PRCA 24, the communication
apprehension total scores

00:02:15.160 --> 00:02:16.150 align:middle line:90%
are there for us.

00:02:16.150 --> 00:02:23.240 align:middle line:84%
We had a mean of 63.66, a
median of 64, a mode of 67,

00:02:23.240 --> 00:02:26.080 align:middle line:90%
a standard deviation of 17.

00:02:26.080 --> 00:02:27.835 align:middle line:84%
Skewness is, of
course, positive,

00:02:27.835 --> 00:02:29.530 align:middle line:84%
so that's going to
be right skewed.

00:02:29.530 --> 00:02:32.800 align:middle line:84%
The Kurtosis is positive, so
it's going to be more peaked.

00:02:32.800 --> 00:02:36.370 align:middle line:84%
We have a range of 96, so
between the bottom number,

00:02:36.370 --> 00:02:39.700 align:middle line:84%
which is 24 and the
top number of 120.

00:02:39.700 --> 00:02:42.100 align:middle line:90%
That's a total of 96 points.

00:02:42.100 --> 00:02:44.680 align:middle line:84%
And that's how you run
descriptive statistics using

00:02:44.680 --> 00:02:45.580 align:middle line:90%
SPSS.

00:02:45.580 --> 00:02:48.630 align:middle line:90%
