Handouts of Lecture 4 (Types of Variables)

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.

Fall 2011 Class: Welcome to the Course & Course Outline

Welcome to the course. This course is designed to give you an overview of statistical techniques for data acquisition and analysis using both manual methods and software. Statistics is the mathematics used for data analysis which one of the most important field because if you are conducting a research, your results will never be valid without applying appropriate statistics. Biostatistics is statistics applied in the biological research including biotechnology.
Good Luck.
