Investigating variation involves examining the differences and changes within and between groups, such as species or individuals, to understand the underlying causes and mechanisms. This can involve collecting data, analyzing patterns, and drawing conclusions about the factors influencing variation, including genetic, environmental, and social influences. Investigating variation involves exploring the differences and similarities within and between groups, populations, or datasets. It's a crucial aspect of research, helping to understand patterns, relationships, and potential causes of change. Here's a more detailed look at what investigating variation entails.
