Question

Design an experiment to determine whether a new drug that is supposed to reduce hyperactivity in children actually does. Your essay should include and identification and description of all the components of your experimental design, including sampling, independent and dependent variables, controls, and the method that you would employ to evaluate the outcome.

Answer 1

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
