However, this does not take into consideration the variation in scores amongst the 50 students (in other words, the standard deviation). After all, if the standard deviation is 15, then there is a reasonable amount of variation amongst the scores when compared with the mean.
Quick Answer. Macrominerals are inorganic nutrients that the human body requires in large quantities because they carry out several critical bodily functions. The most important macrominerals include potassium, calcium, magnesium, sodium, chloride, sulfur and phosphorus.
1. Macro-minerals. They are present in relatively large amounts in the body and are required in fairly large amounts in the diet âmore than 100 milligrams daily. Calcium is the most common and abundant mineral that accounts for approximately 2% of an adult body. An adult of 75 kg contains about 1,5 kg of calcium. Over 99% is found primarily in bones and teeth. Major minerals are calcium, phosphorus, potassium, sodium, chlorine, magnesium and sulfur. 2. Micro minerals or trace minerals. Trace minerals are required by the body in amounts of less than 100 mg/day. Iodine, for instance, accounts for only 0,00003 % of our body, which equals 0,0225 milligram.
