Chebyshev's theorem is a theorem that allows us to approximately know how much percentage of a data set lies within a certain number of standard deviations of the mean of the data set. The mathematical equation to compute Chebyshev's theorem is shown below. 2 of the data lies within k standard deviations of the mean. As stated, the value of k must be greater than 1. Using this formula and plugging in the value 2, we get a resultant value of 1-1/2 2, which is equal to 75%.
Kidney pain and back pain can be difficult to distinguish, but kidney pain is usually deeper and higher in the and back located under the ribs while the muscle pain with common back injury tends to be lower in the back. Causes of kidney pain are mainly urinary tract infections and kidney stones. If a woman is pregnant and has kidney pain, she should contact her doctor. Symptoms of kidney pain may include fever, painful urination, flank pain, nausea, vomiting. Kidney pain can be on the left, right, or both sides.
1. Kidney Pain. Pain and discomfort on the side of the affected kidney is common with a kidney infection. You may also feel a dull pain in your lower back as well as in the genital area. Obviously, every patient with a kidney infection feels different degrees of pain (in fact, some have zero pain) and different symptoms. However, severe pain is common with a kidney infection with many patients complaining of radiating pain in their sides and backs, just below the ribs where the kidneys sit. Many also complain of pain that moves about, or travels from the lower abdomen into the back, and even in the area of the groin.
