Morphological method and Metric methods.
The morphological methods use the descriptive traits of the bone and metric methods look at the quantitive elements o of the bone such as the measurements. (Lesciotto and Doershuk, 208) Metric methods uses a wide variety of bones which can be used 34 bones located in the skull and 43 postcranial. Anthologists can use a computer programme known as FORDISC. Which is used to identify ancestry, sex and stature of skeletal remains. An advantage of this is that the programme can identify more than one more than one piece of biological profile. A disadvantage of this is that the accuracy of FORDISC ranges between 52.2% and 77.8%. (Guyomarch and Bruzek, 20) The advantages of using metric methods is that The disadvantages of the metric method is that the method is dependent on size and shapes of the bones. The size and the shapes of the bones can be various between different populations. Siep and Henneberg (205) believed that the skeletal size differs considerably across pop
ulations and the use of inappropriate discriminate functions can result in misinterpretations of sex Morphological methods are methods which use the look of the bones to identify the sex of skeletal remains. This is the most common way which anthropologists use to identify the sex of the remains.
The Advantages of using morphological methods is that methods such as Klales revised method on the Phlenice method can be modified and applied to juveniles to estimate the sex following the onset of puberty. (Klales and Burns, 207) The disadvantages of using morphological methods on the pelvis to identify the sex of the skeletal remains is that Bruzek and Murail (2006) state that &the level of reliability needs to be higher in the legal context then those presented in current sexing methods (85%) A minimum threshold of 95% is required&morphological sexual differences on the skeleton is not enough to elaborate a method of sexing. No single trait of the human skeleton enables a reliable sex determination. (pp 225).
