The independent variable is the variable that is manipulated to observe its effect on the dependent variable. In this case, teaching half of the children yoga on Wednesday is the variable that is being manipulated, making it the independent variable. The dependent variable is the variable that is being observed and measured, which is the children's attitude towards learning. The control group refers to the group that is not being manipulated, and in this case, it is not specified whether there is a control group or not. Posttest refers to the measurement that is taken after the intervention, which is on Friday in this case, while pretest refers to the measurement taken before the intervention, which is on Monday in this case.
