Why Is The Bell Curve Important? It is important in the field of statistics because they model many real-world data like test results and performance reviews of employees. The bell curve has one mode, and it coincides with the mean and median. … For a bell curve, exactly 95% of the data lies within the
Why Is Normal Distribution Important? The normal distribution is the most important probability distribution in statistics because many continuous data in nature and psychology displays this bell-shaped curve when compiled and graphed. Why normal distribution is so important? It is the most important probability distribution in statistics because it fits many natural phenomena. … For
What Is The Area Under A Graph? The area under a curve between two points is found out by doing a definite integral between the two points. To find the area under the curve y = f(x) between x = a & x = b, integrate y = f(x) between the limits of a and
Where Do Most Scores Fall Along A Normal Curve? Regardless of what a normal distribution looks like or how big or small the standard deviation is, approximately 68 percent of the observations (or 68 percent of the area under the curve) will always fall within two standard deviations (one above and one below) of the
Why Is The Total Area Under The Curve Equal To 1? The total area under the curve for any pdf is always equal to 1 , this is because the value of a random variable has to lie somewhere in the sample space. In other words, the probability that the value of a random variable
