Normal distribution, the most common distribution function for independent, randomly generated variables. Its familiar bell-shaped curve is ubiquitous in statistical reports, from survey analysis and quality control to resource allocation. Learn more abo
The normal curve is bell-shaped with a point of inflection at {eq}\mu \pm \sigma {/eq}. The point of inflection is where the curve changes its concavity, and the point of inflection is equidistant from the mean. Graph of normal distributionNormal...
A normal distribution is the bell-shaped frequency distribution curve of a continuous random variable. Visit BYJU’S to learn its formula, curve, table, standard deviation with solved examples.

Example: Using the empirical rule in a normal distributionYou collect SAT scores from students in a new test preparation course. The data follows a normal distribution with a mean score (M) of 1150 and a standard deviation (SD) of 150. Following the empirical rule: Around 68% of scores ar...
Example #1 – Finding Cumulative Normal Distribution Probability Suppose you are a working professional, and it takes an average of 40 minutes to reach the office. With the standard deviation of 10 minutes (10 minutes late or 10 minutes early) and the assumption that the time it takes you to...

Normal distribution tables are used in securities trading to help identify uptrends or downtrends, support or resistance levels, and other technical indicators. Normal Distribution Example Consider the following 2 datasets: Dataset 1 = {10, 10, 10, 10, 10, 10, 10, 10, 10, 10} Dataset 2...
Example of a Normal Distribution Many naturally occurring phenomena appear to be normally distributed. For example, the average height of a human is roughly 175 cm (5' 9"), counting both males and females. As the chart below shows, most people conform to that average. Taller and shorter peo...
