The empirical rule for a normal distribution suggests that 68% of data will fall within the first standard deviation, 95% within the first two standard deviations, and 99.7% will fall within the first three standard deviations of the mean. If I have a data set where all the elements fall within first two standard deviations of the mean, can I consider this data set as a normally distributed one?

    Isn't there a general rule for this scenario? I have a sample of 100 instances in the current problem that I am dealing with.2012-09-12
