Pile sorts could be used to collect data on social relations among people. Some Anthropologists have used pile sorts technique to collect information on a variety of things such as relevant behaviors on a number of diverse cultural patterns (Weller and Romney, 1990). To use the pile sort, the items to be studied are usually presented in cards. Words could be written on cards for those that are literate. Visual stimuli could be presented to non-literate respondents. The cards are shuffled or randomized for the respondents to make their sorting into piles so that similar items are on a pile together.

Because the speed of the earth in its orbit varies throughout the year, solar noon differs from 12:00 standard time by up to 16 minutes. That difference is known as the equation of time. Because it is difficult to establish the time when the shadow is shortest, this method is not as accurate as the next one described below. But, you can use the length of that line to determine the altitude of the sun at noon (Figure 5). Once the altitude is determined, you can calculate the declination of the sun (Figure 6) (which is, declination (δ) = altitude + latitude − 90) and you can develop a table for the annual variation of the declination of the sun.

Km where there is scarcely any settled population at all except at occasional oases; this same scanty population applies to the Namib and the Kalahari deserts and greater parts of the dense tropical rain forests. g. lake Victoria, on the coastlands of East Africa, the Mediterranean coastlands of North-West Africa and in Ethiopia. With the single exception of irrigated Egypt, all these areas have a mean annual rainfall of over 600 mm. Favourable climate, good soil, accessibility and presence of minerals favour high population density in Africa.
