Choosing the smallest unit of time likely to show systematic variability will provide the most detailed and precise information about the pattern of the data. If a larger unit of time is chosen, there may be a loss of information and variability within that unit of time may be hidden. Additionally, using the smallest unit of time will allow for comparisons with other studies that have used the same unit of time.
