Hi everyone, and welcome

2
00:00:02,640 --> 00:00:05,970
to this third module of Epidemiology 2.

3
00:00:05,970 --> 00:00:08,430
This module has two different objectives.

4
00:00:08,430 --> 00:00:11,430
Our first objective is
to review those measures

5
00:00:11,430 --> 00:00:13,080
of disease frequency,

6
00:00:13,080 --> 00:00:16,620
so things like incidents,
prevalence, and odds.

7
00:00:16,620 --> 00:00:19,530
We're also going to
extend our conversation

8
00:00:19,530 --> 00:00:21,330
about incidents to start thinking

9
00:00:21,330 --> 00:00:26,330
about survival analysis or
time until an event occurs.

10
00:00:27,780 --> 00:00:29,520
The other thing that we're going to do

11
00:00:29,520 --> 00:00:33,120
in this module is to review
statistical inference.

12
00:00:33,120 --> 00:00:36,420
This isn't in our book
chapter, but it's a good thing

13
00:00:36,420 --> 00:00:38,490
for us to review before we move forward

14
00:00:38,490 --> 00:00:42,330
and talk about measures of
association in the next module.

15
00:00:42,330 --> 00:00:45,540
Statistical inference
are those biostat tests,

16
00:00:45,540 --> 00:00:48,870
like t-test and chi square and ANOVA

17
00:00:48,870 --> 00:00:52,156
and you are going to see
this in your SPSS lab

18
00:00:52,156 --> 00:00:56,610
and also in some of the
learning materials below.

19
00:00:56,610 --> 00:00:59,220
If you have any questions,
please don't hesitate

20
00:00:59,220 --> 00:01:02,520
to reach out to me via
email or on Yellowdig.

21
00:01:02,520 --> 00:01:04,953
Take care and I'll see
you in the next module.
