character of p value plot(https://goo.gl/fKom4j <-you can copy and use in your lectures)
1000 tirals and 1000 p's distribution.
do you know this plot is from 1981 when I was an elementary student
Everytime you change the yellow cell, you will get new 1000 p's and their plot.
Each test and p are calculated from two groups which have 100 numbers respectively out of a sigle large group.
This plot shows the multiplicty problem
showing if you get multiple p's, type 1 error will increase.
