How does standard deviation of 0 affect statistical significance?
Standard deviation of 0 can only be attained if all observations are identical. That is, the variable in question has just one possible value so statistical considerations are irrelevant.
What can affect the results of saliva sample testing?
Smoking, eating, drinking, and brushing the teeth can affect test results, as can the way in which the person puts saliva on the slide.
What is the similarities between correlation analysis and regression analysis?
Correlation analysis seeks to establish whether or not two variables are correlated. That is to say, whether an increase in one is accompanied by either an increase (or decrease) in the other most of the time. It is a measure of the degree to which they change together. Regression analysis goes further and seeks to measure the extent of the change. Using statistical techniques, a regression line is fitted to the observations and this line is the best measure of how changes in one variable affect the other variable. Although the first of these variables is frequently called an independent or even explanatory variable, and the second is called a dependent variable, the existence of regression does not imply a causal relationship.

How does sample size affect validity of results in a research?
A large sample reduces the variability of the estimate. The extent to which variability is reduced depends on the quality of the sample, what variable is being estimated and the underlying distribution for that variable.
What will affect the sample size calculation for a clinical trial?
A cost-benefit analysis. In particular, the cost of the experiment, the consequences of getting the wrong result, the rarity (or otherwise) of the condition that you want to study, the variability of that condition in the population.
Do results affect causes?
