Hello the new programmer

 1. Control is very important.  2. Independent variables are the things we change and have levels. E.g. the ages of participants 3. Dependant variable are measures being observed, tested, and/or collected. E.g. rating scale 4. constants are things that cannot practically change. E.g. speed of lights 5. Covariates are a factor you cannot control but need to account for. E.g. intervention depression but people have different level of depression.  6. Control group is a group that are shield from exposure to variable.  7. Within and Between subject Factors. Sex factor would be between factors.  8. Random.org to generate pseudo numbers. 9. Order Effects: The context Effects, practice effects, pattern recognition, fatigue effects. 10. Dealing with Context and Practice  is Trying.  11. Dealing with Practice is counterbalancing in factorial design.  12. Systematic counterbalance concerns ensuing equal distribution of condition orders. 

 CLR (Common Language Run-Time) is an application sitting in the computer memory. Its main functionality is translating Intermediate Language (IL) code to Native Code. Let's say you compile a program on Windows machine, and then try to run it on Linux, it won't work. C# uses CLR program to translate the IL Code to Native code which is called Just-in-time Compilation (JIT). Therefore, if you write C# code in a different application, you don't have to worry about compiling the code into Native code of different machines as long as you have CLR that can run your application.  Namespace is a container for related classes. Assembly (DLL or EXE) is a container for Namespace.
