Hello, all kaskuser. Good day!

Due to my thesis research, I am still considering variable X and Y (research problem).
There must be two X variables and 1 Y variable.

Example : THE EFFECTIVENESS OF MIND MAPPING AND PRACTICE IN IMPROVING STUDENT’S DESCRIPTIVE WRITING PERFORMANCE

Variable X1 : mind mapping
Variable X2 : practice
Variable Y : students' descriptive writing performance

I want to do a simple research that only needs questionnaire as the instrument.

Do you have any suggestions for me?
Thank you.
