00:00:01.740 --> 00:00:03.870
<v ->Welcome to module two.</v>

2
00:00:03.870 --> 00:00:06.900
This module is typical of the next few modules.

3
00:00:06.900 --> 00:00:10.380
We'll build on material like epi study designs

4
00:00:10.380 --> 00:00:12.690
by incorporating more advanced concepts

5
00:00:12.690 --> 00:00:15.120
than what you learned in Epi 1.

6
00:00:15.120 --> 00:00:17.190
We'll explore methods like matching

7
00:00:17.190 --> 00:00:20.910
and how to control for age as a confounding variable.

8
00:00:20.910 --> 00:00:23.460
Don't wait to get started on this content.

9
00:00:23.460 --> 00:00:26.160
You have your first chapter from the text to read

10
00:00:26.160 --> 00:00:29.640
and you'll realize that those chapters are pretty long.

11
00:00:29.640 --> 00:00:34.470
One comment on the text, it's a pretty dry and dense book.

12
00:00:34.470 --> 00:00:36.630
However, it currently is the best

13
00:00:36.630 --> 00:00:40.380
and only intermediate Epi 2 book on the market.

14
00:00:40.380 --> 00:00:43.320
The public health program feels that the material is solid

15
00:00:43.320 --> 00:00:46.230
and informative and continues to review the market

16
00:00:46.230 --> 00:00:48.063
for a more engaging option.

17
00:00:49.350 --> 00:00:51.810
The lectures are a summary of the book chapters

18
00:00:51.810 --> 00:00:54.330
but don't hit on every detail,

19
00:00:54.330 --> 00:00:55.740
so the readings are important

20
00:00:55.740 --> 00:00:58.650
as a supplemental source of information.

21
00:00:58.650 --> 00:01:01.290
I will say that if you find the information

22
00:01:01.290 --> 00:01:04.530
in the book to be especially dense or confusing,

23
00:01:04.530 --> 00:01:07.620
really do think about it as a supplemental resource rather

24
00:01:07.620 --> 00:01:11.253
than worrying too much about absorbing all of the details.

25
00:01:12.540 --> 00:01:17.040
There is also an SPSS lab associated with this module

26
00:01:17.040 --> 00:01:19.590
which I'd encourage you to get a headstart on.

27
00:01:19.590 --> 00:01:22.680
Within the lab folder there is some supplemental material

28
00:01:22.680 --> 00:01:26.850
if you need any additional SPSS support or a refresher

29
00:01:26.850 --> 00:01:28.470
as you dive in.

30
00:01:28.470 --> 00:01:31.830
I'd encourage you to work together on the labs as well

31
00:01:31.830 --> 00:01:35.640
as to ask lab related questions using the help forum tag

32
00:01:35.640 --> 00:01:37.020
in Yellowdig.

33
00:01:37.020 --> 00:01:39.840
You can feel free to either answer each other's questions

34
00:01:39.840 --> 00:01:42.720
directly in Yellowdig or feel free to tag me

35
00:01:42.720 --> 00:01:45.300
in a post if you'd like me to weigh in.

36
00:01:45.300 --> 00:01:46.650
I'll talk to you next week.
