Statistics is the mathematical science pertaining to the collection, analysis, interpretation, and presentation of data. It is used across many fields to analyze past data and make predictions. Some key terms in statistics include the mean, which is the average value found by dividing the sum of all data points by the total number of data points. The mode is the data point that occurs most frequently. The median divides the data into two equal parts and represents the middle value. Statistics helps us make comparisons and informed decisions in areas like business, agriculture, education, medicine, sports, and more.

BiostatisticsDr. Senthilvel Vasudevan - Biostatistics refers to applying statistical methods to biological and medical problems. It is also called biometrics, which means biological measurement or measurement of life.
- There are two main types of statistics: descriptive statistics which organizes and summarizes data, and inferential statistics which allows conclusions to be made from the sample data.
- Data can be qualitative like gender or eye color, or quantitative which has numerical values like age, height, weight. Quantitative data can further be interval/ratio or discrete/continuous.
- Common measures of central tendency include the mean, median and mode. Measures of variability include range, standard deviation, variance and coefficient of variation.
- Correlation describes the relationship between two variables

Statistics
StatisticsVjvaniShree statistics, the science of collecting, analyzing, presenting, and interpreting data.
Data are the facts and figures that are collected, analyzed, and summarized for presentation and interpretation. Data may be classified as either quantitative or qualitative. Quantitative data measure either how much or how many of something, and qualitative data provide labels, or names, for categories of like items. For example, suppose that a particular study is interested in characteristics such as age, gender, marital status, and annual income for a sample of 100 individuals. These characteristics would be called the variables of the study, and data values for each of the variables would be associated with each individual.
Methods of probability were developed initially for the analysis of gambling games. Probability plays a key role in statistical inference; it is used to provide measures of the quality and precision of the inferences. Many of the methods of statistical inference are described in this article. Some of these methods are used primarily for single-variable studies, while others, such as regression and correlation analysis, are used to make inferences about relationships among two or more variables.

Discrete mathematics for real world applications
Discrete mathematics for real world applicationsMuntasirMuhit Discrete mathematics is used in many areas of the real world. It is used by Google Maps to determine fastest driving routes and times using simpler algorithms for small maps and more complex techniques for large maps. Computer graphics, web searching, digital image processing, and speech recognition all use linear algebra to transform and manipulate objects, return multilingual search results, merge images and apply filters, and recognize speech. Scheduling problems involving assigning shifts, routes, rooms, or meetings use graph coloring or combinatorial optimization from discrete mathematics. Encoding data for barcodes, RFID tags, and other formats uses discrete mathematical techniques to store information efficiently and reduce errors. Cell phone networks assign frequencies so phones do not interfere using concepts from graph theory and discrete optimization.

ABSTRACT: I give an introductory discussion of two key philosophical controversies in statistics in relation to today’s "replication crisis" in science: the role of probability, and the nature of evidence, in error-prone inference. I begin with a simple principle: We don’t have evidence for a claim C if little, if anything, has been done that would have found C false (or specifically flawed), even if it is. Along the way, I’ll sprinkle in some autobiographical reflections.

Statistics in real life
- 1. WHAT IS STATISTICS? •“The word ‘statistics’ and ‘statistical’ are derived from the Latin word status, means political state •“ It is a mathematical science pertaining to the collection, analysis, interpretation or explanation, and presentation of data. Also with prediction and forecasting based on data.
- 2. INDEX •What is Statistics? • Statistics in daily life • Mean • Mode • Median • Conclusion
- 4. Statistics in real life • INDUSTRIES AND BUSINESS Report of early sales & comparison others. It shows where the factory or its sales lack and where they are good .
- 5. Statistics in real life • AGRICULTURE What amount of crops are grown this year in comparison to previous year or in comparison to required amount of crop for the country Quality and size of grains grown due to use of different fertilizer.
- 6. Statistics in real life •EDUCATION Money spend on girls education in comparison to boys education? Increase in no. of girl students who seated in who Seated for different exams?
- 7. Statistics in real life •ECOLOGICAL STUDIES Comparison of increasing impact of pollution on global warming? Increasing effect of nuclear reactors on environment?
- 8. Statistics in real life • FORESTERY How much growth has been occurred in area under forest or how much forest has been depleted in last 5 years? How much different species of flora and fauna have increased or decreased in last 5 years?
- 9. Statistics in real life •MEDICAL STUDIES No. of new diseases grown in last 10 year. Increase in no. of patients for a particular disease. SPORTS Used to compare run rates of to different teams. Used to compare to different Players result for last 10 years.
- 10. Statistics in real life • Use of Graphs Nowadays graphs are used almost everywhere. In Stock Market, graphs are used to determine the profit margins of Stock.There is always a graph showing how prices have changed over time , unemployment figures , inflation , exchange rates , NASA space stories , global warming statistics , mortgage lending figures , house price comparisons ,inflation , budget forecasts. taxation or pension forecasts , Food prices , and how they have changed over time etc.
- 11. MEAN •The mean is used as one of the properties of statistics. It is defined as the average of all the clarifications. •The mean of a number of observations is the sum of the values of all the observations divided by the total number of observations. It is denoted by the symbol x , read as ‘x bar’.
- 12. MODE •The mode is that value of the observation which occurs most frequently, i.e., an observation with the maximum frequency is called the mode. •The no. of games succeeded by any team of players.The frequency of the need of infants. Used to find the number of the mode is also seen in calculation of the wages, in the patients going to the hospitals, the mode of travel etc.
- 13. MEDIAN •The median is that value of the given number of observations, which divides it into exactly two parts. • It is used to measure the distribution of the earnings Used to find the players height e.g. football players.To find the middle age from the class students. Also used to find the poverty line.
- 14. CONCLUSION • Statistics and probability are important for making decisions in life. • Statistics should be taught to all students in primary and secondary school. • Statistics is not mathematics.The methods sometimes uses mathematics, but the basic ideas do not require advanced math. •We need to focus on concepts and importance of statistics.
