We fabricated a proportional counter of gas-flow type for educational use. The structure of the counter is different from general structure, and can be used like a commercially produced GM counter. Saran Wrap (poly vinylidene chloride - [CH_2CCl_2]_n-) was used as the entrance window of the radiation. And the instantaneous adhesive was also used to make up the counter in several hours. Many measurements were carried out in order to confirm the performance of the counter. Time series measurement data of the natural radiation were arranged, and the possibility as a teaching material of Poisson distribution and Gaussian distribution was examined. These data will be applied to lectures of studying test of rejection of observation in statistics. All students will feel statistics as a real consideration of natural phenomenon by means of using practical data.
