Abstract:
Identification of an individual plays a vital part of any medicolegal investigation. Fingerprint is considered to be the most accurate and reliable indicator in identification. The present study was conducted on 500 South Indian subjects to determine the individuality and the predominant fingerprint pattern among South Indian population. Two-hundred and fifty males and 250 females of South Indian origin were included for this study and rolled prints were taken from all the 10 digits and the same were stored on a proforma. The most frequent fingerprint pattern was ulnar loop in the total population, as well as in the sex wise distribution.

Methods of Classification and Identification
Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
Testing a Claim about Mean: Unknown Population SD
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used; instead...
