How do you find the standard deviation from a frequency table? How do you find standard deviation from a frequency table? X is normally distributed with mean, 1000, and standard deviation, 250. What is the probability that X lies between 800 and 1,100?
The meaning of STANDARD DEVIATION is a measure of the dispersion of a frequency distribution that is the square root of the arithmetic mean of the squares of the deviation of each of the class frequencies from the arithmetic mean of the frequency distrib
