statistics

 [stah-tis´tiks]
1. a collection of numerical data.
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.
vital statistics data, usually collected by governmental bodies, detailing the rates of birth, death, disease, marriage, and divorce in a population.

sta·tis·tics

(stă-tis'tiks),
1. A collection of numeric values, items of information, or other facts that are numerically grouped into definite classes and subject to analysis, particularly analysis of the probability that the resulting empiric findings are due to chance.
2. The science and art of collecting, summarizing, and analyzing data that are subject to random variation.

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. See Actuarial statistics, Coefficient of variation, Cusum statistics, Descriptive statistics, Health statistics, Mean, Standard deviation, t test.

Q. What are the known statistics of Autism: Here is a question which needs a very detailed reply please. What are the known statistics of Autism: incidence, cost and ratio?

A. for more statistical information here are 2 sites:

and here is the CDC site link:

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 number of women having breast cancer or under the threat of having breast cancer? where would i find a good , and reliable info about the disease ?

A. it is said that today 1 out of any 8 women will have breast cancer. there are also men who has breast cancer but the numbers are considerably lower.
about a good source of info- the site that doctoradhi gave you is pretty good, and you can use also the national medical library link:
http://www.nlm.nih.gov/medlineplus/breastcancer.html#cat22

good luck!
