Difference between sample and sampling frame?
A sample is a smaller group selected from a larger population. It may be to costly and time consuming to carry out the study on the whole population so the researchers choose a sample and often generalise results.A sample frame is the list of people from which a sample for the study are selected. It is only carried out on the target population that the researcher is interested in studying. For example finding data on just school children would not involve the the whole population only children in schools.
Longitudinal study versus cross-sectional study?
A longitudinal study and a cross-sectional study are methods of collecting scientific data. A longitudinal study is the method that gathers data on a subject for a particular period of time and the subject's response to particular variables. A cross-sectional study is where more than one subject is used for the collection of data at different points in time in response to particular variables. These types of studies are sometimes used to determine correlation.

Strengths and weaknesses of snapshot study?
Strengths: Snapshot studies provide a quick, cost-effective way to collect data on a specific topic at a specific point in time, offering a snapshot of a situation. They can be useful for identifying trends or patterns and can be completed relatively quickly. Weaknesses: They may not capture changes that occur over time, lack the ability to establish causation, and may not provide a comprehensive understanding of the topic being studied due to their brief and limited nature. Additionally, they may be subject to bias or inaccuracies if not conducted carefully.
