Abstract
Psychologists do more than just wonder about human behavior, they conduct research to understand exactly how people feel, think, and behave the way they do. In the lifespan development, most research is on groups of individuals. These groups can be studied at one point in time, (cross-sectional) or at many different times (longitudinal). The most complicated design is called a sequential design. Good sampling is very difficult to achieve, because most research depends upon people volunteering to be participants. Other variables that might be important in research study could include race, sex, culture, economic status, education, religion, and employment. Understanding how psychologists do research is vital to understanding psychology itself.

In the lifespan development, most research is on groups of individuals. These groups can be studied at one point in time, or at many different times. The main aim of the longitudinal study is to analyze change over time. It is an observational study in where participants are studied repeatedly. True longitudinal study rely on panel data and panel methods where the same individuals are measured on more than one occasion checking the same variables. The other benefit of longitudinal study is that it permits investigators to identify common patterns as well as individual differences in development examine relationships between later events and behaviors. However, the
