00:00:00,840 --> 00:00:04,560
Hi everyone, and welcome to
the second module of EPI-2.

2
00:00:04,560 --> 00:00:05,910
What you'll see in this module

3
00:00:05,910 --> 00:00:09,240
is going to be typical
of the next few modules.

4
00:00:09,240 --> 00:00:10,770
We'll review some content

5
00:00:10,770 --> 00:00:12,510
that you've already learned previously,

6
00:00:12,510 --> 00:00:14,700
and then we'll build on this content

7
00:00:14,700 --> 00:00:16,950
with more advanced material.

8
00:00:16,950 --> 00:00:20,100
In this module, you're going
to see EPI study designs

9
00:00:20,100 --> 00:00:22,140
and then build on what
you've learned before

10
00:00:22,140 --> 00:00:24,930
with some more advanced EPI study designs,

11
00:00:24,930 --> 00:00:27,870
and we'll look at how we
can alter our study designs

12
00:00:27,870 --> 00:00:30,480
to decrease potential confounding.

13
00:00:30,480 --> 00:00:34,770
My message for you this week
is don't wait to get started.

14
00:00:34,770 --> 00:00:36,900
You have a chapter to
read in your textbook,

15
00:00:36,900 --> 00:00:40,320
and you'll see that your textbook
chapters are pretty long.

16
00:00:40,320 --> 00:00:42,840
I also want to make a
note about your textbook

17
00:00:42,840 --> 00:00:44,580
before we go forward.

18
00:00:44,580 --> 00:00:45,960
I'll be honest with you guys,

19
00:00:45,960 --> 00:00:50,130
it's pretty dry compared to the
Gordis Epidemiology textbook

20
00:00:50,130 --> 00:00:52,080
that we've used for EPI-1.

21
00:00:52,080 --> 00:00:56,340
It is however, the best and
only intermediate EPI-2 textbook

22
00:00:56,340 --> 00:00:57,750
that's on the market,

23
00:00:57,750 --> 00:01:00,510
so I do really apologize for the dryness,

24
00:01:00,510 --> 00:01:04,920
but please do try to get as
much out of it as you can.

25
00:01:04,920 --> 00:01:06,900
Because our textbook is so dry,

26
00:01:06,900 --> 00:01:09,930
I have purposefully included a lot of text

27
00:01:09,930 --> 00:01:12,240
in the lectures for this module.

28
00:01:12,240 --> 00:01:14,070
Work through the lecture content

29
00:01:14,070 --> 00:01:18,870
before attempting to work
through the textbook chapters.

30
00:01:18,870 --> 00:01:20,550
The other thing that you have this week

31
00:01:20,550 --> 00:01:23,670
is your first SPSS lab assignment.

32
00:01:23,670 --> 00:01:27,510
And this also isn't short, so
please do get started early.

33
00:01:27,510 --> 00:01:29,970
You'll see that there's
some additional information

34
00:01:29,970 --> 00:01:32,670
about SPSS, some videos to watch,

35
00:01:32,670 --> 00:01:35,160
and some additional
support should you need it

36
00:01:35,160 --> 00:01:37,500
for the SPSS assignment.

37
00:01:37,500 --> 00:01:41,100
The resources on the SPSS page
are designed for everyone,

38
00:01:41,100 --> 00:01:44,040
regardless of your background with SPSS.

39
00:01:44,040 --> 00:01:46,350
Take some time to look
through the resources,

40
00:01:46,350 --> 00:01:51,090
watch the videos, and follow
along in your own SPSS software

41
00:01:51,090 --> 00:01:54,420
to make sure you feel comfortable
with what is presented.

42
00:01:54,420 --> 00:01:56,550
Learning or advancing your knowledge

43
00:01:56,550 --> 00:01:59,580
of a statistical software is really hard.

44
00:01:59,580 --> 00:02:02,790
Here are two things that I found helpful.

45
00:02:02,790 --> 00:02:05,220
The first is don't be
afraid to play around

46
00:02:05,220 --> 00:02:08,640
with the software, don't be
afraid to click on things,

47
00:02:08,640 --> 00:02:12,480
try things out and see if you
can start to figure it out,

48
00:02:12,480 --> 00:02:16,500
what SPSS is doing behind the scenes.

49
00:02:16,500 --> 00:02:19,740
The second thing that I found
useful is working with others,

50
00:02:19,740 --> 00:02:22,890
so I encourage you to work
with each other on these labs

51
00:02:22,890 --> 00:02:24,630
using Yellowdig as a forum

52
00:02:24,630 --> 00:02:27,540
so that you can get the most out of SPSS.

53
00:02:27,540 --> 00:02:30,720
Feel free to post
screenshots of your outputs.

54
00:02:30,720 --> 00:02:32,820
Ask if others are getting similar results

55
00:02:32,820 --> 00:02:36,360
or verify that your understanding
of something makes sense.

56
00:02:36,360 --> 00:02:38,400
You can really learn a lot from each other

57
00:02:38,400 --> 00:02:40,500
and this discussion and collaboration

58
00:02:40,500 --> 00:02:43,440
is going to be really good
for your long-term retention

59
00:02:43,440 --> 00:02:45,690
of the material and learning.

60
00:02:45,690 --> 00:02:48,540
This mimics the real
world of asking colleagues

61
00:02:48,540 --> 00:02:51,210
or the internet for help when you run into

62
00:02:51,210 --> 00:02:53,190
an analytic challenge.

63
00:02:53,190 --> 00:02:54,600
If you have any questions,

64
00:02:54,600 --> 00:02:56,850
please don't hesitate to get in touch

65
00:02:56,850 --> 00:02:59,493
and I'll see you in the
next module, take care.
