a researcher wants to describe how fine motor skills change as a group of infants age from 18 to 24 months. Describe how this study could be done as a cross-sectional design. Next, describe how this study could be done as a longitudinal study.

Fine motor skills are developmental in nature, that is, they become more advanced with age. To assess the progress of fine motor skills in infants, it is necessary to observe the advancements that take place at different stages of time. Two research methods that are suited to observing behavioral changes are cross-sectional studies and longitudinal studies.
Cross-sectional studies are a type of research design where subjects of different ages are studied for one variable across all of them to understand how age affects that variable. In this case, multiple infants ranging from 18 to 24 months will be studied to assess their fine motor skills.
