2. the mathematical science dealing with the collection, analysis, and interpretation of numerical data using the theory of probability, especially with methods for drawing inferences about characteristics of a population from examination of a random sample.

statistics,

n the branch of mathematics that gathers, arranges, condenses, coordinates, and mathematically manipulates obtained facts so that the numerical relationships between those facts may be seen clearly and freed from anomalies resulting from chance factors.

statistics, descriptive,

n.pl the statistics used to describe only the observed group or sample from which they were derived; summary statistics such as percent, averages, and measures of variability that are computed on a particular group of individuals.

statistics, inference,

n.pl the inferences made regarding characteristics or general principles about an unseen population based on the characteristics of the observed sample. Statistical findings from a sample are generalized to pertain to the entire population. The process of drawing inferences, making predictions, and testing significance are examples of inferential statistics.

statistics, nonparametric,

n.pl the sta-tistical methods used when the statistician cannot assume that the variable being studied is normally distributed in a population. Also called
distribution-free statistics.

Statistics 1. A collection of datapoints or numerical values that can be categorized and subject to analysis; statistics are the raw material on which conclusions about cause-and-effect relationships are based 2. The field that formally studies cause-and-effect relationships; the systematic collection, classification, and mathematical compilation of data vis-á-vis amount, range, frequency, or prevalence; those methods for planning experiments, obtaining data, and organizing, summarizing, presenting, analyzing, interpreting, and drawing conclusions.

Patient discussion about statistics.

Q. Do you know if Propecia can truly stop hair loss and even grow back hair. do you have any statistics about it? do you know if there are any side effects to this medication?

A. it does work but there is some side affects, as in E.D. while you are on the med.

Q. what is the statistic of smoking people , let say , people who smoked for almost 30 years , to get a lung cancer or any other diseases related to smoking ? will they be in a risk group ? what are the variable of thing like that ?

A. although it is REALLY proven that smoking is correlated with higher incidence of lung cancer (and other diseases), but there are also a lot of smokers who are "healthy" where they don't have any complain or any manifested diseases.

Compared to nonsmokers, men who smoke are about 23 times more likely to develop lung cancer and women who smoke are about 13 times more likely. Smoking causes about 90% of lung cancer deaths in men and almost 80% in women.

But I still remember clearly when I was in medical school, that my professor told me 90% cause of lung cancer is smoking, BUT 90% smokers all around this world don't have lung cancer, hehehe.. ironic, isn't it?

Q. What is the rate of alcoholism in the USA compared to the rest of the world? What is the rate of alcoholism in the USA compared to other countries in the world. I don't mean amount of alcohol consumed, but alcohol addiction/dependency. Links to your sources would be appreciated. Cheers! (pun intended)

A. here is a link to a CDC table about drinking hobbits of Americans:

here is an article about it, and it gives good links also:
