Overview of Statistics

Statistics is crucial for planning studies, experiments, and interpreting data.
Involves organizing, summarizing, presenting, analyzing data, and drawing valid conclusions.

Application in Biostatistics

Biostatistics applies statistical tools specifically to biological sciences and medicine.
Important in a variety of fields: business, education, psychology, agriculture, and economics.

Data Definition and Collection

Data consists of collected observations, including measurements or survey responses.
A single value is termed as a datum; examples include patient weight (e.g., 64 kg) or temperature (e.g., 37 degrees Celsius).

Sources of Data

Routinely Kept Records

First source to explore for data, such as hospital medical and accounting records.
Contains extensive information on patient care and business activities within healthcare facilities.

Surveys

Useful when existing records do not provide necessary data.
Example: A clinic might survey patients to determine their mode of transportation for visits if this information is absent from admission forms.

Experiments

Data may be collected from experiments designed to test specific strategies or hypotheses.
Example: Nurses can evaluate different motivational strategies for patient compliance through controlled experiments to determine effectiveness.
