## 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

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.

## 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. numerical facts pertaining to a particular subject or body of objects.

2. the science dealing with the collection, tabulation and analysis of numerical facts.

**inferential statistics**

conclusions, usually quantitative, drawn from an analysis of data.

**salvage statistics**

statistical technique used in an attempt to derive some useful information from a poorly designed or poorly executed experiment.

**vital statistics**

see vital statistics.

## Patient discussion about statistics

**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!
