Normal Bell Curve Percentages. Normal distribution or Gaussian distribution named after Carl Friedrich Gauss is one of the most important probability distributions of a continuous random variable. Between 0 and Z option 0 to Z less than Z option Up to Z greater than Z option Z onwards It only display values to 001. The IQ bell curve helps categorize where people fall along the scale of intelligence and does so in a neatly compartmentalized way. The empirical rule allows researchers to calculate the probability of randomly obtaining a score from a normal distribution.
683 of the population is contained within 1 standard deviation from the mean. 95 of the population will lie within 2. 68 of data falls within the first standard deviation from the mean.

The distribution is centered around the number seven and the probability decreases as you move away from the center. 683 of the population is contained within 1 standard deviation from the mean. The empirical rule allows researchers to calculate the probability of randomly obtaining a score from a normal distribution.
