1. In probability theory, a log-normal (or lognormal) distribution is a continuous probability distribution of a random variable whose logarithm is normally distributed.
2. Move the vertical line to the left or right to display the point (x/Pr(x)) data in the upper left of the graph.
3. Thus, if the random variable Y is log-normally distributed, then ln(X) has a normal distribution.
4. For Data Entry the Laplace Distribution app utilizes three Sliders.
5. The Lognormal PDF graph displays (x/Pr(x)) data pairs.
6. The First Slider enters the Random Variable (x).
7. The Second Slider enters the Standard Deviation (σ) value.
8. The Third Slider enters the Standard Mean (μ) value.
9. Upon touching the graph a vertical line appears.
10. Likewise, if Y has a normal distribution, then X = exp(Y) has a log-normal distribution.
11. The vertical y-axis plots a range of Pr(x) values.
12. Liked Lognormal Distribution? here are 5 Education apps like Bell Curves - graphing calculator for the normal distribution function; Probability-Distributions; Chi-Square Distribution; F-Distribution Function; Cauchy Distribution Function;
