To enhance the validity and reliability of the research, it is recommended to change the test variable to examine the effect of different types of childhood vaccines on transmission rates of measles. By considering different types of vaccines, the research question and experiment can be refined to provide a more comprehensive understanding of measles transmission and the effectiveness of various vaccines.
To improve reliability, repeating testing trials should be conducted. By conducting multiple trials, any inconsistencies or outliers can be identified and accounted for, ensuring that the results are more reliable and representative of the true effect of the vaccines on transmission rates.
Addressing limitations is also crucial in improving the validity of the outcome. By modifying the research design to address any limitations, such as controlling for confounding variables or adjusting for biases, the validity of the findings can be enhanced. This may involve refining the experimental procedures, selecting a larger and more diverse sample, or using more robust statistical methods.
Overall, by modifying the research question, experiment, and addressing limitations, the validity and reliability of the study can be significantly improved, providing more accurate and valuable insights into the effect of childhood vaccines on measles transmission rates.
In regard to the modification, it is suggested to change the test variable to enhance all pieces of evidence. To refine research question and experiment, different type of childhood vaccine will be considered the process of creating reliability repeating testing trials or change the test variable of effect of measles on transmission rate will then enhance the validity of the outcome improved upon by modify addressing limitations.
