One-year-old Jude Immanuel Bijoy was among five children shifted from the cardiothoracic intensive care unit (ICU) of MIOT Hospital in Chennai Thursday when the hospital realised it could not manage critically ill patients as flood water had knocked out power and oxygen supply for 48 hours.
Now we have to be very careful. There are two standard deviations listed on the calculator. The symbol Sx stands for sample standard deviation and the symbol stands for population standard deviation. If we assume this was sample data, then our final answer would be.
For example, in the population {4, 8}, the mean is 6 and the deviations from mean are {-2, 2}. Those deviations squared are {4, 4} the average of which (the variance) is 4. Therefore, the standard deviation is 2. In this case 100% of the values in the population are at one standard deviation of the mean. The standard deviation is the most common measure of statistical dispersion, measuring how widely spread the values in a data set are. If the data points are close to the mean, then the standard deviation is small.
