The normal distribution curve describes the types of curves theory. The designated representative of the series, whether it is the mean, median and mode are equal. The nature of the distribution normal curve that themselves are a bell curve inverted (Ball Shaped), by linking the frequency of detection of Quetelet and Galton in the 19th century by studying the characteristics of the frequency of the data set size. Large (Infinite Population) In fact, the data collection. Collected from a sample (Finite Sample) will be seen that the retention of samples is sometimes resemble a normal distribution curve. If the available storage size 
frequency characteristics that are indicative of the normal curve of notification. If the report is a graph. To see the distribution of information. The formula mathematicians German Carl Gauss has made the conversion to make it easier to replace the following equation can be seen as a major logarithmic and the Z2 with the raw scores from the data set distribution curve normally. will Raw scores were converted to z scores, it will be the standard. It can be seen that there are many scholars who have translated the formula C (Z- Scores) in the area under the normal distribution.
