I'm going to start off with an easy one.

Here's the definition.....
Deviation of results or inferences from the truth, or processes leading to such systematic deviation. Any trend in the collection, analysis, interpretation, publication, or review of data that can lead to conclusions that are systematically different from the truth.

What am I :?: Give 3 'types' of it while you're at it, too.
(Remember to hide your answers)

Okay, so...
--[b][u]Bias[/u][/b]--
Three types of bias are [u]selection bias[/u], which is the selection of subjects into your sample or their allocation to treatment group that produces a sample that is not representative of the population; [u]measurement bias[/u], which is when the measurement of outcomes is inaccurate, possibly because of inaccuracy in the measurement instrument or bias in the expectations of study participants, careers, or researchers; and [u]analysis bias[/u], which is when not all participants remain in the group to which they were allocated and complete the follow up.
Hopefully that's the right way to hide the answer. If not, I apologize. :)

So, do I ask a question now..?

Yup, that's the right answer and the correct way to hide it. :)

Your turn to ask a question now, too.

Alright, here's another relatively simple one.

What is an epidemic curve (i.e. say what the horizontal and vertical axis's represent)? Also, what are the different shapes of the curve and what do they signify?

The x-axis represents the amount of time.
The y-axis represents the number of cases.

Point Source signifies an outbreak usually relating to a common cause and happen in a brief amount of time, where it rapidly increases then declines slower.
Continuous Common Source signifies that the common source had an extended duration of exposure time.
Propagated (Progressive Source) signifies that the infection for the first outbreak is the source of infection to the next outbreak that is a source for later outbreaks.

Well, I feel a little impatient (since my answer is not replied to) and so I will continue the question marathon from here.

I will go with a vocabulary question:

What is the definition of a pathogen?

An agent that causes disease, including bacteria, fungi, parasites, viruses etc.
Yes, this marathon is so slow, barely anyone posts on it. WHERE ARE ALL THE DISEASE DETECTIVES?????
