Abstract :

The lognormal distribution is one of the important continuous distributions in statistics and due to the fact that it is positively skewed and effect of variety of forces working independently on the variability of lognormal distribution is multiplicative, it has many applications in Biological and Medical Sciences. Many of its descriptive characteristics and its relationships with other distributions have been explored and found to be very useful and interesting. As we know the lognormal distribution is positively skewed and positively skewed distributions are particularly common when mean values are low and variances are large and values cannot be negative, many measurements in Biological and Medical sciences show more or less skewed distribution and due to this fact the lognormal distribution is playing a major role in Biological and Medical sciences as compared to normal distribution. For example, the distribution of incubation period of infectious diseases; distributions of chemicals and organisms in the environment; distributions of sensitivity to fungicides in populations and distribution of population size; the distribution of times to the appearance of lung cancer in cigarette smokers, etc., have been shown to be log-normally distributed. In this paper, an attempt has been made to discuss detailed applications of lognormal distributions in different areas of Biological and Medical Sciences based on the data collected from Eritrea and other countries and it has been observed that lognormal distributions is a better fit.
