.في كل بحث يوجد عندنا مايسمى بالمتغير وهو اللي نبي نجربه او نقيسه
In each research there is something called variable that's we want to test or measure it
1. Independent variable : variable that is manipulated by the researcher
(or the variable that is thought to affect the outcome/dependent variable)
المتغير الذي يتم التلاعب به من قبل الباحث
Computers and their effects on student's achievement. The Independent variable is # Computers
2. Dependent variable : variable that is measured to assess the effects of the independent variable
المتغير التابع: المتغير الذي يتم قياسه لتقييم الآثار المترتبة على المتغير المستقل
Why we can’t manipulate the variable In a dependent variable. لماذا لا نستطيع التعامل مع المتغير في المتغير التابع.
Because we want to measure the effect of the independent variable.
3. “Operational definition” : procedure for measuring and defining a construct
تعريف التشغيلي": إجراءات لقياس وتحديد البناء
Research Hypothesis# RH: Question is previously answered by different research
سؤال أجيب عليه من قبل في بحوث مختلفة
Research Hypothesis came from# Literature Review.(previous research)
A hypothesis is # a statement that describes or explains a relationship among variables
A hypothesis It is# a prediction that is derived from your research question.
A research question # Rh: is the question that You ask through your research
A research question # Rh: Question is something not answered before.
a prediction is# derived from your research question
don't choose samples cause you like them or they are only around you << that's called bias.التحيز >
