Answer & Explanation :-
Research Design is the overall strategical blueprint layout of research; denoting about collection, measurement, analysis of data
- Data variables are independent & dependent variables.
- Dependent variable is the variable being effected by other variables. In this case, it is 'Hyperactivity in children'
- Independent variable(s) are the causal variables which effect the dependent variable. In this case, it is 'New Drug'
- Data is collected through sampling method. Sample of children will be selected from entire population of children.
- Data is analysed on the basis of relationship between variables, through hypothesis testing
- Null Hypothesis [H0] : New drug has no impact on children hyperactivity
- Alternate Hypothesis [H1] : New drug decreases children hyperactivity
