This topic continues from the computer problem. I realize if the Window operation systems are less support, the switching OS is sound good. Now I use Mac X OS. It’s going to be O.K. The problem is fixed. It is no class today but keeps working all the time. I read the validity and reliability of statistic method. The major topic is the convergent and discriminant validity that measure correlation relativity between a couple variables. The square of coefficient in convergent validity is between zeros to one that reverse in percentage to explain how many dependent variable can explain dependent variable.
