-**BEFORE GOING FURTHER: ​ You will need an introduction to the Poisson probability distribution function Po$(\Lambda)$. ​ NOTE:  To avoid confusion with the symbol $\lambda$ used later in this lab manual for the "​absorption coefficient",​ we use upper-case $\Lambda$ for the mean of the Poisson distribution. ​ The videos, mentioned next use lower-case $\lambda$ for this mean.  Please try to avoid the possible confusion. ​ We use  +**BEFORE GOING FURTHER: ​ You will need an introduction to the Poisson probability distribution function Po$(\Lambda)$. ​ NOTE:  To avoid confusion with the symbol $\lambda$ used later in this lab manual for the "​absorption coefficient",​ we use upper-case $\Lambda$ for the mean of the Poisson distribution. ​ The videos, mentioned next use lower-case $\lambda$ for this mean.  Please try to avoid the possible confusion. ​ We use upper-case $\Lambda$ for the mean.**

The easiest way to do this is to watch a series of two //YouTube// videos called //​Statistics:​ Poisson Distribution - Introduction.// ​ In these videos the distribution is symbolized by Po$(\Lambda)$. The easiest way to do this is to watch a series of two //YouTube// videos called //​Statistics:​ Poisson Distribution - Introduction.// ​ In these videos the distribution is symbolized by Po$(\Lambda)$.
