A cross-sectional study involves looking at people who differ on one key characteristic at one specific point in time. The data is collected at the same time from people who are similar in other characteristics but different in a key factor of interest such as age, income levels, or geographic location. Participants are usually separated into groups known as cohorts. For example, researchers might create cohorts of participants who are in their 20s, 30s, and 40s.
How and When Cross-Sectional Studies Are Used
This type of study uses different groups of people who differ in the variable of interest but who share other characteristics such as socioeconomic status, educational background, and ethnicity. Cross-sectional studies are often used in developmental psychology, but this method is also utilized in many other areas including social science and education.
