Answer:
Replication
Explanation:
The 3 main principles of experimental deisgn
1. Randomisation
2. Replication
3. Blocking
Replication
This has different definition. It is when a researcher repeats that is replicate research findings through correct use of operational definitions, procedures, etc.
A good research mut be replicated and it must result in the same or similar in terms of findings each time the experiment is performed.
It also implies that the treatment used in an experiment was used more than once in an experiment. It because allows us to estimate the inherent variability in the data. This allows us to know and judge if an observed difference in treatment was as a result that is it could be due to chance variation.
Replication is very important because when we have one experiment or treatments once, we would not know if the observed difference is due to the treatments or just random variability. But replication helps you to know the reason for the observed differences.
Answer: The two possible study design are; "COHORT STUDY" and "CROSS-SECTIONAL STUDY".
Explanation: Cohort study design is an observational study in which people who receives a particular treatment or are under a particular condition, are been observed and studied. This type of research model also allows a researcher to compare people affected by a condition to people unaffected by the same conditions.
The investigator is likely to use the cohort design because it will help in studying the children that are always exposed to smoke, and to observe the affected and unaffected children.
The CROSS-SECTIONAL design is an observational study in which a specific population are studied at a particular time. This type of research allows the researcher to study the difference in that population at a time interval.
This study design is likely to be used by the investigator, because it will help the investigator to determine the amount of secondhand smoke each child inhale at a particular time. It will also help the investigator to know the outcome of each child after 5years
