Biostatistics Basics

Which field of study is concerned with the collection, organization, summarization, and analysis of data?

What do statisticians try to do with the results of their analysis?

Which book is mentioned as a reference for basic concepts and methodology in the health sciences?

In which field are the tools of statistics employed when the analyzed data are derived from biological science?

What is the main focus of biostatistics?

True or false: Tables are the simplest way to summarize data?

True or false: Charts and graphs are visual representations of data?

True or false: A title for a graphic should express who, what, when, and where?

True or false: The table shows the percent contribution of reported malaria cases by year in Kenya between 2000 and 2007?

True or false: The total number of malaria cases in 2004 was 7,545,541?

Data Presentation in Research

Effective data presentation enhances clarity, conciseness, and actionability.
Attractive presentations engage audiences and improve retention of information.

Tables vs. Graphs

Tables summarize data in absolute numbers or percentages, providing straightforward comparisons.
Charts and graphs offer visual representations of data, helping to convey patterns and trends effectively.

Key Considerations for Graphs

Each graphic must have a clear title indicating the subject matter.
All components within the graphic should be labeled for easy interpretation.
Source of the data, along with the date, should be included to establish credibility.
Provide the number of observations (n=xx) for context.
Footnotes can be added for additional information as needed.

Example of Data Representation

A table illustrates the relative frequency of reported malaria cases in Kenya from 2000 to 2007.
Data includes:
- Yearly number of malaria cases, providing a count and relative frequency percentage.
- For instance, in 2004 there were 7,545,541 cases which contributed 15% to the total.

Title Selection Guidelines

A title should encapsulate five W's: Who, What, When, Where, enhancing understanding of the dataset at a glance.
