This document provides an introduction to biostatistics. It defines biostatistics as the application of statistical tools and concepts to data from biological sciences and medicine. The two main branches of statistics are described as descriptive statistics, which involves organizing and summarizing sample data, and inferential statistics, which involves generalizing from samples to populations. Several key statistical concepts are also defined, including populations, samples, variables, data types, levels of measurement, and common sampling methods. The objectives are to demonstrate knowledge of these fundamental statistical terms and concepts.

• It is a specific branch of mathematics that deals with analysis of data collected on various population groups
• Statistics involves mathematical abilities more than addition, subtraction, division and multiplication which are repeated many times in a logical fashion.
• for fuller details of statistical tests may refer to Chandha (1992); Vincent (1995); Hopkin et al. (1996); Sincrich et al. (2002); Triola (2002)
• Understanding of basic statistics is indispensable for dealing with the process of evaluation of test and measurement.
• The statistical concepts facilities proper and effective interpretation of test scores or measurements taken by the coach or a physical educator
• While a computer assists the teacher or the coach in saving the huge time needed for enormous calculations, but the meaning of results is made clear only through the understanding of relevant statistical test concepts.
• Tests act as seed to measurements, the statistical tests act as seed to the construction of all other types of tests and are also essential for the testing of validity, reliability and objectivity of all tests.
The information which we can deduce from test and measurement is based on our statistical ability. It is the statistical tools which enable us to do the following important functions:
1. Organize and tabulate date (presentation of facts in a definite form)
2. Analysis data
3. Synthesize data (classification / combination of facts)
4. Compare groups of data
5. Simplification of unwieldy and complex data
6. Proper interpretation of a data
7. testing of hypotheses
8. understand the relationship and association between different parameters, make predications and take decisions.
9. Construction of physical, psychomotor and written tests
10. Evaluation of individual measurements
11. selection of sportsperson
12. Monitoring of training and teaching effects and testing the need for individualization of training and teaching.
13. Meaning: The word “statistics” is a plural form of ‘statistic’. The term statistic is uncommon to that an extent that many of the students of statistics may be unaware of its singular form. The word statistics has been taken from German word ‘statistik’ meaning a political state. Since, facts and figures were required in olden days mainly by kings for their administration. Therefore, in the beginning. It was also known as the ‘Science of Kings’ (Chadha, 1992). Subsequently, its scope has greatly widened and statistics now refers to a huge body of methods, symbols and formulae dealing with phenomena that can be described numerically providing quantitative arrays of information
14. Statistic is numerical value which characterizes a group of scores. For example the average height characterizes the entire sample whose all subjects’ heights have been measured to calculate the average height. A number of such characterizing values refer to the plural form of above mentioned statistic and thus, give rise to the more commonly used

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

2 Case Reports of Gastric Ultrasound
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

3. Objectives of the chapter
Demonstrate knowledge of statistical terms.
Differentiate between the two branches of
statistics.
Identify types of data.
Identify the measurement level for each
variable.
Identify the basic sampling techniques.

4. * Biostatistics:
4
The tools of statistics are employed in many
fields:
business, education, psychology, agriculture,
economics, … etc.
When the data analyzed are derived from the
biological science and medicine,
we use the term biostatistics to distinguish this
particular application of statistical tools and
concepts.
5. Definition of Statistics?
Statistics is the science of conducting studies
to collect, organize, summarize, analyze, and
draw conclusions from data.
Statistics The science of collecting, describing,
and interpreting data.
Statistics is the study of how to collect,
organize, analyze, and interpret numerical
information from data.
Bio-statistics is the branch of applied statistics
that applies statistical methods to biological
science and medicine.
5
6. Types of Statistics
The two areas of Statistics are: Descriptive
statistics and Inferential statistic.
Descriptive statistics involves methods of
collection, organizing, picturing, and
summarizing information from samples or
populations.
Inferential statistics consists of generalizing
from samples to populations, performing
estimations and hypothesis tests, determining
relationships among variables, and making
predictions.
6
7. In descriptive statistics the statistician tries to
describe a situation. Consider the national
census conducted by the Somaliland
government every 10 years. Results of this
census give you the average age, income, and
other characteristics of the Somaliland
population.
The area of inferential statistics called
hypothesis testing is a decision-making
process for evaluating claims about a
population, based on information obtained
7
8. Reasons to study Statistics
Statistics is an important tool for Planning, research, decision
making and problem solving.
In diverse areas such as business, financial management, education
policy, we use statistical analysis to make decisions.
It is a tool for scientific description and inference.
It helps to know how to properly present information.
It helps to recognize problems with published information.
It helps to know how to draw appropriate conclusions from data.
It helps to improve processes.
To obtain reliable forecasts.
8
9. A population consists of all subjects (human
or otherwise) that are being studied.
Most of the time, due to the expense, time,
size of population, etc. it is not possible to use
the entire population for a statistical study;
therefore, researchers use samples.
A sample is a group of subjects selected from
a population.
An individual is a person or object that is a
member of the population being studied.
9
11. Sampling
Sampling is the process of selecting
observations (a sample) to provide an
adequate description and inferences of the
population.
Sample
It is a unit that is selected from population
Represents the whole population
Purpose to draw the inference
Why Sample?
Sampling Frame Listing of population from
which a sample is chosen
11
15. Statistical Sampling: Items of the sample are chosen based on
known or calculable probabilities.
Simple Random Sampling : Every possible sample of a given
size has an equal chance of being selected. Selection may be
with replacement or without replacement.
Stratified Random Sampling : Divide population into
subgroups called strata according to some common
characteristic and select a simple random sample from each
subgroup and then combine samples from subgroups into
one.
Systematic Random Sampling : Decide on sample size :n.
Divide frame of N individuals into groups of k individuals
k=N/n. Randomly select one individual from the 1st group.
Select every kth individual thereafter.
Cluster Sampling : Divide populations into several “clusters”
16. Non Probability sampling
Convenience Sampling
Quota Sampling
Judgmental Sampling (Purposive
Sampling)
Snowball sampling
16
17. Non Probability sampling
Convenience Sampling
Convenience sampling involves choosing
respondents at the convenience of the
researcher
Judgmental Sampling (Purposive Sampling
Researcher employs his or her own "expert”
judgment about.
Quota Sampling
The population is first segmented into mutually
exclusive sub-groups, just as in stratified
17
18. Non Probability sampling
Snowball sampling
The research starts with a key person and
introduce the next one to become a chain
18
19. Variables and Types of Data
To gain knowledge about seemingly
haphazard situations, statisticians collect
information for variables, which describe the
situation.
A variable In statistics, variables are
measurable characteristics of things (persons,
objects, places, etc) that vary within a group of
such things
Data is a collection of facts or measurements
attributed to an entity.
Examples are a list of percentage scores of
19
21. 21
Quantitative Variables
Definition
A variable that can be measured numerically is called a
quantitative variable. The data collected on a
quantitative variable are called quantitative data.
Qualitative or Categorical Variables
Definition
A variable that cannot assume a numerical value but
can be classified into two or more nonnumeric
categories is called a qualitative or categorical
variable. The data collected on such a variable are
called qualitative data.
22. 22
Quantitative Variables cont.
Definition
A variable whose values are countable is called a
discrete variable. In other words, a discrete
variable can assume only certain values with no
intermediate values.
Definition
A variable that can assume any numerical
value over a certain interval or intervals is
called a continuous variable.
23. Source of Data
JWP 2007 23
Routinely Kept Records: Day to day records or data kept by
institutions
Census: A count or measure of the entire population
Survey: A count or measure of part of the population.
Experiment: Apply treatment to a part of the group
External Sources: Data Exist in form published Report
24. Level (Scale) of Measurement
The appropriateness of the data analysis
depends on the level of measurement of the
data gathered. Four common levels of data
measurement follow.
1. Nominal
2. Ordinal
3. Interval
4. Ratio
The nominal level of measurement classifies
data into mutually exclusive (non-overlapping)
categories in which no order or ranking can be
24
25. The ordinal level of measurement classifies
data into categories that can be ranked;
however, precise differences between the
ranks do not exist.
25
26. The interval level of measurement ranks data,
and precise differences between units of
measure do exist; however, there is no
meaningful zero.
26
27. The ratio level of measurement possesses all
the characteristics of interval measurement,
and there exists a true zero. In addition, true
ratios exist when the same variable is
measured on two different members of the
population.
27
