Describe the Longitudal, Cross-sectional sequence design used in Lifespan development research.

Longitudinal studies assess changes over an extended period of time by looking at the same groups of subjects for months or even years. Looking at academic and social development, we may choose a small sample from each of the low- and high-income areas and assess them on various measures every six months for a period of ten years. The results of longitudinal studies can provide valuable qualitative and quantitative data regarding the differences in development between various groups. (Heffner)
A cross-sectional study involves looking at people who differ on one key characteristic (such as age) at one specific point in time. The data is collected at the same time from people who are similar on other characteristics but different on a key factor of interest such as age, income levels and geographic locations (Cherry, 2016)
What are the advantages and disadvantages to Longitudinal and cross-sectional research? For Longitudinal the advantages would be that you are able to collect individual differences, and to determine patterns and detect any developmental changes. The disadvantages would be that amount of time it takes, and that you need a large sample group. During the research you are using a group of people from various sample groups over a period of time. For example would be you start with the age group 20, and every ten years you study them to see the changes they have…
