what is the same recall period??
Answers
Explanation:
The recall period must be carefully defined to include or exclude specific seasons. If you include a deadly season of the year, such as the rainy season when mosquito breeding takes place and malaria transmission is greatest, you will end up with a higher mortality rate. If you wish to compare this rate to prior estimated rates which did not include this season, you may falsely conclude that the risk of death has increased for some other reason when the apparent increase is only due to seasonal variation..
I hope this is help you
Answer:
This means that the longer the recall period, the bigger the sample size (in person-time units) Therefore, the longer the recall period, the more precise will be your estimate of the mortality rate if the same number of households are selected for the survey sample.
