明することを可能にしたポアソン分布説明教具。 A Poisson distribution data sheet consisting of one or more transparent disks of one or more types,
One or more types of data sampling chips each having a constant area ratio with respect to the Poisson distribution data sheet and which are transparent disks, and a step is provided from the opaque peripheral parts 3B and 3C where the transparent circular smooth part 3A is in contact with 3A. It consists of a Poisson base with a low structure, and under an overhead projector, these Poisson distribution data sheets, data sampling chips, and Poisson bases are combined as necessary, operated, projected, and delivered to many students. A Poisson distribution explanation tool that allows you to efficiently explain Poisson distribution at once.
