Here is the instruction sheet for instructor: Instruction for instructor to facilitate the data collection.
Microsoft Word 28kB May17 07 The equipment for conducting this activity are a one-foot actual or paper-copy ruler and b Computer station with Internet connection. The best classroom setting is a computer classroom with Internet connection.
Students can also enter their own data using any computer that has Internet connection after class. Prior to conducting this activity, the instructor needs to: During the session of conducting the group activity, Start with the discussion on how to measure hand size and ask students to compare different ways of measuring hand size in terms of a is the measurement measures 'hand size', b is it easy to measure, and c how well can it be measured repeatedly.
Comparing Hand-length from wrist to tip of the middle finger and hand-width from the tip of the thumb and the tip of little finger, when stretching out the handThey both are valid measurements, easy to measure. Hand length is more repeatable.
Ask students to go to the Real-Time Hands-on Activities and direct them to enter the data. Ask student to make an 'educated' guess as to which one 'hand length' or 'hand width' a better predictor and their reasons. Then, make a comparison later after the analysis.
Outlier cases may occur. For example, Based on how hand-length and width are measured in this activity, hand-width is always longer than hand-length. If a case that shows hand width is shorter than hand-length, this provide a discussion on measurement error and the effect of outliers. The hand-size data for the worksheet has a case with hand-width shorter than hand-length.
Students are asked to analyze the data, firtst, without knowing this case, then, investigate the data, and delete this case, re-analyze the data and make a comparison.
The use of this activity beyond introductory level: This activity may be used to introduce models with both qualitative gender and quantitative hand length predictors. This activity may be used to introduce the concept of muliticollinearity by using both hand length and hand width as predictors.LITTLE FINGER AND YOUR PERSONALITY--LOW SET MERCURY FINGER (PALMISTRY)
This activity may be used to introduce variable selection techniques by including gender, hand width, and hand length as predictors. Assessment Students are assessed using Classroom Group activity worksheet: Excel 11kB May15 This activity assesses students' overall knowledge of bivariate relationships.
In this data, there is a case that has measurement error; Hand-width is shorter than Hand-length. This error occurred when the student did not stretch out the hand for taking the hand width. Students are asked to analyze this entire data. Then, they are asked to locate this measurement error case, identify at least two more possible errors that may occur. Delete the case, re-analyze the data and make a comparison.

Stature is considered as one of the parameters for personal identification Krishan and Sharma, ; Anitie, The most important applications of anthropology at field level include biological anthropology, epidemiology, clinical application and in metabolic research Bidmos, ; Bidmos, The hand length could be used to predict body weight status and body surface area independent of the sex of the individual Bidmos, Correlation between hand length and foot length has also been studied and that if the hand length is known, the foot length can be predicted and vice-versa.
Hand length has been shown to be a reliable and precise means in predicting the height of an individual Gauld and Rakhir, ; Ebites et al. In forensic investigations, the dimensions of the hand and foot have been used in the determination of sex, age, stature of an individual.
Stature reconstruction is important as it provides forensic anthropological estimation of the height of a person in the living state which plays a vital role in the identification of individual remains Bhatnagar et al.
Intact long limb bones have been used in the derivation of regression equations for stature assessment in different population groups. Anthropologist observes and compared the relation between body and segments to highlight variations between and within groups.
How well can hand size predict height?
Determination of stature is a major concern in forensic medicine and forensic anthropology Fessler et al. The bone area values at different sites strongly correlates to muscle strength and also correlate to body size; height, weight, lean mass, fat mass and body mass index BMI Fessler et al, It is commonly accepted that standards for skeletal identification vary among different populations and the standard for one population may not be used for another Thakur and Rai, ; Iscan, Establishing personal identification of the victims is often required and the estimation of stature from extremities and their parts plays an important role in identifying the dead in forensic examinations Nath et al.
When the health risk is defined in terms of body size, Western Caucasian standards have, by default become the international standard. Although by far the most long term data available on health risks are from Caucasian subjects, there is mounting evidence that these Western standards may not be applicable to Africans and Asians Krishan and Sharma, The reconstruction of body stature has been a subject of study since the beginning of the nineteenth century in the specialized areas of forensic anthropology which deals with the application of methods and techniques of analysing skeletal remains Trotter and Glesser, ; Iscan, ; Iscan, The aim of the present study was to investigate if height could be predicted using hand length, age and other body measurements in Nigerian School Children of Gbagyi ethic group.
Materials and Methods 2. The sample consists of males and females with each school having males and females with no known physical deformities between the ages of years.
The inclusion criteria include that participants must be boys and girls between the ages of years of age, of Gbagyi tribe from both parents and grandparents within Abuja Area of Nigeria and without any known Physical or Mental deformity.
Methodology The demographic data of the subjects collected include the age in years, name, place of birth, parental and grandparental origin were completed in the questionnaire. Standing height, hand length and weight measurements were done taken. Standing height was measured to the nearest centimetres cm using a Stadiometer with subject standing erect on a horizontal resting plane bare footed having the palms of the hands turned inward and the finger pointing downwards and the height was then converted to the nearest meters m.
The height was measured from the sole of the feet to the vertex of the head as recommended by International Biological Program Mauthausem and Gusen, ; WHO, The body weights of the subjects were taken using the mechanical weighing balance to the nearest kg according to the standard procedures Yyagi et al. Body Mass Index BMI is a number calculated from a child's weight and height, and is a reliable indicator of body fatness for most children and teens.
The hand length was measured with a calibrated non stretch tape from distal crease to the tip of the middle finger in extension as described by Amirsheybani et al. The measurements and readings from each subject were taken twice and recorded and if the two measurements and readings for each parameter agreed within 0. When the two initial measures did not satisfy the 0. Differences were declared significant when P — value is less than 0.
To investigate the utility of hand length, weight, age and BMI in height estimation, linear and multiple linear regression analysis were used.
The mean value for height in female Children was 1. Anthropometric measurements in male and female children of Gbagyi tribe of Abuja Table 2. Anthropometric parameters used according to age groups in male of Gbagyi tribe of Abuja The results in Table 3 show the mean and standard deviation of height, weight, hand length and BMI of each age group in both males and females.
Anthropometric parameters used according to age groups in female of Gbagyi tribe of Abuja The result in Table 4 shows the correlation matrix of the anthropometric parameters studied. The table shows the standard error of estimate SEE not more than 0.
Multiple linear Regression of height m from the dimensions used in male and female children of Gbagyi tribe of Abuja 4. Discussion The result of the present study showed that the dimension of hand length, age, weight and body mass index can successfully be used for the estimation of height. The parameters showed a significant correlation with height in both male and female Nigerian school children of Gbagyi tribe of Abuja-Nigeria Hence these can be used by law enforcement agents and forensic scientists to identify fragmentary and dismembered human remains in Nigerian school children of Gbagyi descent of Abuja.
Since it has been established that long bones are the most appropriate specimen for height evaluation and estimation Iscan, ; Jasuga et al. It has been shown in this study that there was a significant correlation between height and hand length and with age, weight and BMI in male and female of Nigerian school children of Gbagyi tribe of Abuja. The use of anthropometric methods is available in case of athletes in which the bone area values at different sites of the body are strongly related to muscle strength and parameters related to body size such as height, weight, lean mass, fat mass and body mass index according to Ruff, and Jasuga et al.

Thus morphometric estimation of body mass from skeletal size appears to work reasonably well in both normal and highly athletic modern humans Ruff, ; Jasuga et al.
The present study shows that the weight could be correlated with height and with BMI in Nigerian school children of Gbagyi Abuja. This shows that the higher the height, the lower the BMI and the higher the athletic performance according to Ruff, ; and Munzo et al.
Estimation of height using various physical measurements has been attempted by many researchers but the one variable that proves to be consistently reliable in the estimation of height is the hand length Shintaku and Funiyay, ; Kanchan et al. The result from the present study show that hand length can be used to predict height, together with age, weight and BMI. The present study shows the parameters used to determine height can also be used to determine hand length because there was 2-tailed significant correlation between hand length and age, weight, height and BMI in both male and female Nigerian school children of Gbagyi tribe of Abuja.
Analysis of genetically disparate population reveals a clear pattern of sexual dimorphism, with women consistently having smaller hand proportionate to stature than men Saxena, ; Lundy and Feldsman, Therefore while varying in degree across populations in general; women have proportionately shorter hands than men but results from the present study show that males have shorter hand length than females which disagrees with the established pattern of men having longer hand length than women according to Quamra et al.
This could be as a result of the study being carried out with underage children of ages between years Nigerian children of Gbagyi tribe of Abuja. Scientifically it is known that a female child grows faster than a male child which indicates that a female child have longer hand length than the male children. The present study tried to create specific regression equations which could help in prediction of heights of Nigerian school children of Gbagyi tribe of Abuja.
The equation for estimating height from hand length measurement of school children of Gbagyi tribe of Abuja Nigeria differs from those presented by Bhartnagar et al. This could be due to the differences in the average values of parameters studied. The differences could also be due to the different methods and parameters used in the present study. In conclusion, the results from the present study indicated that hand length is a proxy indicator for height when it is difficult or not possible to measure height directly, and also other variables such as age, weight and BMI stand as indicator for predicting height among Gbagyi school children of Abuja in Nigeria.
