Links for classification for the lab assignment

Dear Students
Here are some links for checking on classification data for your your lab assignment:

Integrated Taxonomic Information System
Global Biodiversity Information Facility
Encyclopedia of Life
Species 2000

Lecture No 1 Handouts

Introduction to the course: The mathematics of data arrangement, analysis and interpretation. Experimental planning and designing is also an important part.

Course policies: as in course outline

Importance of biostatistics: This is important in data analysis and more importantly in designing the experiments. Experimental designing is one of the most critical steps in research. At this stage, the knowledge of statistics is very important. Statistics is required to validate the results and interpret from result. Also, making impressive and useful presentations in the for of tables and charts is also an important subject of biostatistics.

Details of contents was discussed too.

Remember! Handouts are not an alternative to your class notes.

Activate you accounts @fccollege.edu.pk

All students must activate their fccollege.edu.pk email accounts immediately. You can do this by seeing Mr. Ghaus Mohammad in room 205. These will be required for forgotten password issues related to your Student Web Account and is your authentic email to contact administration or faculty at Forman. 
When faculty/administration send an email at your address you are supposed to be able to access it.Therefore activate now. This will serve as an alternate to SMS!

Lecture 4 handouts (types of variables)

Biol 205 Biostatistics

Lecture 04

A Variable

A variable is a characteristic of an individual which take different values at different situations, e.g. age, height, weight, smoking habit etc.

Types of Variables

Variables / data of a planned experimental study may be classified into 2 main categories:

1. Qualitative / Categorical

Population is classified into various categories and data is recorded in the form of “counts”, this is called qualitative data / variables. For example gender (male, female), eye color, hair color, complexion of skin etc.

These variables are measured as discrete / discontinuous numbers (no decimal places, and cannot be divided into fractions). For example number of rats in an experiment.

2. Quantitative / Numerical

When we make observations numerically and the variable to be measured is numerical value then this is called qualitative data / variable. For example blood glucose level, height etc.

These variables are measured as continuous numbers that is capable of taking every possible value between two given numbers is termed as continuous. For example, age, weight (52.5 kg).

Variables are also classified based upon their relationship with each other

Dependent and Independent Variables

A dependent variable is also called a response variable, i.e. its value depends upon value of some other variable.

An independent variable is sometimes called a predictor variable, it is usually set or changed by the experimenter.

For example, prevalence of a disease in different age groups; in this study age is independent variable and prevalence of disease is dependent variable.

Project in Biostatistics

Dear Students

Your project in BIOL 205 - Biostatistics is due on February 02, 2012. This project accounts for 10 marks and 5% towards your final grade.

There are two topics, which are below:

1. Search any three research articles on "significance of experimental design in biotechnology, biology or environmental science". Read these articles and after making an idea or concept write down an article on the topic above.
2. Think of a research question of your interest / choice. Develop a research hypothesis and design an experiment to test it. Then create a supposed data and analyze it by hypothesis testing techniques and make a report.

Good luck.

Quiz 2

Dear Students

Your quiz 2 will be held on tomorrow, January 17, 2012. Topic include introduction to experimental design and between group and within group experimental designs. Timings and location are 8:00 am and S-433.
