A statistic (singular) or sample statistic is any quantity computed from values in a sample that is used for a statistical purpose. Statistical purposes include estimating a population parameter, describing a sample, or evaluating a hypothesis. The average (aka mean) of sample values is a statistic.

Statistics is the study and manipulation of data, including ways to gather, review, analyze, and draw conclusions from data. The two major areas of statistics are descriptive and inferential statistics. Statistics can be used to make better-informed business and investing decisions.

A statistic is a number that represents a property of the sample. For example, if we consider one math class to be a sample of the population of all math classes, then the average number of points earned by students in that one math class at the end of the term is an example of a statistic.

Statistical knowledge helps you use the proper methods to collect the data, employ the correct analyses, and effectively present the results. Statistics is a crucial process behind how we make discoveries in science, make decisions based on data, and make predictions.

Characteristics of Statistics Statistics are numerically expressed. It has an aggregate of facts. Data are collected in systematic order. It should be comparable to each other. Data are collected for a planned purpose.

Statistics are used behind all the medical study. Statistic help doctors keep track of where the baby should be in his/her mental development. Physician’s also use statistics to examine the effectiveness of treatments. Statistics are very important for observation, analysis and mathematical prediction models.

The mean is often used in research, academics and in sports. When you watch a baseball game and you see the player’s batting average, that number represents the total number of hits divided by the number of times at bat. In other words, that number is the mean.

Statistics help in providing data as well as tools to analyze the data. Some powerful techniques are index numbers, time series analysis, and also forecasting. These are immensely useful in the analysis of data in economic planning. Further, statistical techniques help in framing planning models too.

Statistics is mostly used by doctors to explain risk to patients, accessing evidence summaries, interpreting screening test results and reading research publications [3] . …

By identifying statistical trends and trails, health care providers can monitor local conditions and compare them to state, national, and international trends. Health statistics provide empirical data to assist in the allocation of public and private funds and help to determine how research efforts should be focused.

The use of statistics thus allows a clinical researcher to draw reasonably accurate inferences, despite the uncertainty inherent in the biological systems. The need for statistics in medicine extends beyond research – into daily clinical practice.

Statistics refers to numerical facts. As a branch of knowledge it refers to collection, presentation analysis and interpretation of data. Statistics is very important in education as it helps in collecting, presenting analysis and interpreting data. It also helps in drawing general conclusion.

The main sources of health statistics are surveys, administrative and medical records, claims data, vital records, surveillance, disease registries, and peer-reviewed literature.

Mortality statistics are the rates at which a specific population group die of certain diseases and conditions….Mortality and Morbidity Statistics

Health information is readily available from reputable sources such as: health brochures in your local hospital, doctor’s office or community health centre. telephone helplines such as NURSE-ON-CALL or Directline. your doctor or pharmacist.

Health statistics include both empirical data and estimates related to health, such as mortality, morbidity, risk factors, health service coverage, and health systems. The production and dissemination of health statistics is a core WHO activity mandated to WHO by its Member States in its Constitution.

Accurate, comprehensive, high-quality data and statistics are not only central elements of evidence-based public health policy. By raising health awareness among the general public, they can also help achieve better social and health outcomes and reduce health inequalities.

Other areas of continuing statistical contribution include survey planning and analytic methodology, data-collection systems, detection algorithms and scan statistics to document health trends and identify emerging health issues, and model development to project disease incidence and injury or numbers of cases …

Statistics knowledge is essential for reading and understanding public health research. Review of a random sample of publications from top tier general public health journals showed descriptive statistics and tabular results were reported in more than 95% of the articles.

(1) Statistics helps in providing a better understanding and accurate description of nature’s phenomena. (2) Statistics helps in the proper and efficient planning of a statistical inquiry in any field of study. (3) Statistics helps in collecting appropriate quantitative data.

Doctors were chosen as the first source of information by 87.6% (283/323) of the participants, and they were completely trusted by most of the population (326/411, 79.3%). The second most commonly used source was pharmacists (112/194, 57.7%), and they were partially trusted by 41.4% (159/384) of the participants.
